Just send your heads and intake to Lloyd Elliott and get a custom grind cam. Or get some lt4 heads or intake and port those, aftermarket heads aren't really necessary. Oem optispark the only way to go unless you go 24x conversion and run ls coils. Been in the lt1s for 10 years. People just get mad when the their 20 year old water pump starts leaking and their 20 year old optispark goes bad.
Hey I just got a 95 cadillac fleetwood with 320K on it. Before I got it I already knew that I was going to go the ls route or see about rebuilding and upgrading the lt1 motor. With that said I'm leaning towards the lt4 heads w/lt4 intake, upgrade the cam, along with doing the 24x conversion. Would that be a more cost efficient way to go or is there a better way? It's a fleetwood so I'm not looking to out run vettes and z28s, just want some more power to get the boat rolling quicker and surprise a few folks with a mild sleeper fleetwood!
bought a 92 c4 w/lT1. installed trickflow topend kit, new msd opti and waterpump. dougs shortys bigger throttle body and injectors. running 7.90s in the eighth and the AC still works.
@@Prince_.A I think I bought one from summit. I believe if I had it to do over again I would go the route of the remote water pump that mounts on bottom of radiator. I’d like to see how that would work and solve a problem inherent to these opti LT1 motors.
My personal opinion im a fan of that car dont do that build it Sr my older bro had this engine in 97 camaro it was a monster trust what hes saying bro real i watch him every new episode
Hey man seriously no funny shit speaking from personal experience LS swap it. I’ve got a 94 z28 and it was literally nothing but fucking problems. Yeah the guru is fucking awesome but this isn’t a guide to fix your problems it’s a guide to throw your problems away.
Just LS swap it 😂 never heard that before 🙄 seriously though if you want to be like everyone else go ahead and do that. Much easier to work on and with than the LT1 but if you really do the homework and research the LT1 is where it’s at. I have a 1994 trans am lt1 that I’m putting in my lt1 Roadmaster It’s not gonna be cheaper to swap it to LS because you already have the LT1 on hand and all the parts there to make it operate correctly. There are numerous ways to overcome the opti junk some super cheap some not so much IF do the research and legwork 0411 swap is about $150 and the time to repin some plugs or swap to a coil on plug LS type ignition with junkyard parts for $300-400. If you had nothing to start with sure LS swap it but you have a 10.5 .1 compression 4 bolt main aluminum headed badass engine already that with just a cam upgrade and tuned properly will give you plenty of power. And the lt1 looks 10 times better than an ugly ass LS 😂
@@BIGWILL0715excuse me pardon my lack of knowledge but does the 1990 Camaro iroc also use optispark? Asked because I was looking to buy a older Camaro so I'd have a sporty fun car but reliability is mandatory
Oh yeah!!! Good looking My 96 Imp about to be Nasty!!! I’ve only done a Jet performance chip (old), K&N cold air system, and 3.73 gears. I love when it scratch second off that hard shift! Time to get active 💪🏾
Send your heads and intake to Lloyd elliot to get them ported have him also get you a custom grind cam kit, his port work is damn near as good as those afr heads and will make power. Next look up a torqhead or efi live ignition conversion kit, it does away with the opti spark all together and converts it to coil on plug like the LS 24x style. The gen 2 LT1 still is a great engine and can beat alot of LS cars but when the LS came out in 98 everybody moved on and forgot about these engines.
Yeah if you are a lt1 guy you know what’s up. Do you run a coil on plug 24x reluctor wheel setup? I have gathered all my parts for the 4x 0411 pcm now but the more and more research I’ve done I am 95% sure I can get the coil on plug set to work on the lt1 without buying the really expensive torque head or efi kit.
had a '95 chevy caprice with the lt1 as a patrol car in the hood. between the 3 shifts, that car was in a pursuit atleast twice a week in summer. engine never quit. it needed a brake job every couple months tho.
C4 top speed is 168 with LT1 and for a 25 year old car is *phenomenally* quick. I've beaten STis and even an Audi S4 with mine, I would recommend downshifting...lol
Torque head has a conversion kit that deletes the optispark. Or you could go carberated with a points style distbuter. I drive my optispark daily tho and it's fine
Facts. People only rave about the MSD because of brand & the price. When in reality you talk to guys in the forums there's plenty that have had issues. Every opti is hit or miss and people don't realize the best opti is the original GM opti with the yellow cap. There's literally no company that currently makes the Mitsubishi sensor so brand and price doesn't matter it's really all about the warranty lol.
All the issues with the LT1 engine have been figured out I got a 1996 Buick Roadmaster estate wagon collector's edition and I changed out the water pump for a better brand new water pump and Opti-Spark system IT TOLLS 5,000 LB HORSEPOWER 300 REAR WHEEL DRIVE 8 SEATS 8 SEAT BELTS I CAN'T COMPLAIN
You can always throw a liberal and thick layer of di-electric grease over the cap sealing surfaces along the side. That was the suggestion on car forums, and it served me well.

For those wondering the LT1 in the B-bodies are a little bit different than the ones that came in the C4's and F-bodies. The B-body LT1s have two bolt mains and the cam profile isn't as aggressive, they have a different name too but I'll always call them LT1s.
Hmmm that’s not exactly true my guy. The engine is called a lt1 if it’s an LT1 the only one that isn’t is the 4.3 “baby LT1” which looks just like a 5.7 lt1 but is gutless junk and sadly some people think they bought a “LT1” and get ripped off. Anyways the lt1 s in the B body’s and (D body Fleetwood caddy)had iron heads instead of aluminum like f body’s and vett. The camshaft was different to give it more torque for the much heavier cars and they were tuned far less aggressively that’s it. And as far a 4 bolt or 2 bolt officially I think the only lt1 that supposed to have them were the vets but in actuality you have about a 50/50 chance of dropping the oil pan and seeing 4 bolt mains imo based my experience
@@yeahididit9054 4.3l L05 was dropped in 93, B-bodies 94 and up have an LT1. The B-bodies LT1 is a two bolt main with cast iron heads, the vet's and Camaros have 4 bolt mains and aluminum heads. The B-body LT1 has 40 horsepower less than the Corvettes. Not like it matters though, both can handle 500hp.
Everyone shits on the opti. I have a 95 vette with the lt1 as long as you are pay attention to your car do routine checks on the fluids and watching the waterpump, issue is guys don’t care for their cars enough to check it once a week and don’t realize they are loosing coolant on shutdown or even while driving, I just replaced my water pump at the first sign of a leak. No opti issues and about 800 miles past the pump change
At almost 400,000 miles and several water pump failures never had a optispark issue.had it in deep enough water to suck water into the air filter without any issues
I swear the 9C1 Caprice with the LT1 had a different tune from the factory compared to the Impala SS. I used to beat my friends 95 Impala SS every time by 1.5 car lengths with my 95 Caprice 9C1. We both had the LT1 and both had same mods (air intake, headers, and 3.73 gears), yet I always pulled on him for some reason lol.
I built 2 yrs ago that makes 1575 hp I used torque head as a replacement for the opti and holley terminator max built a custom gear ratio 4l80 with a trans brake 410 gears and 35lbs of boost. My advice is have the block machined and put together and splay to a 4bolt main caps this thing is a real monster
I truly believe don't nobody love cars more than you the vast amount of knowledge you have is passion driven in my opinion your one step away from what ever you wanna do in the car industry
You know your stuff it’s entertaining to listen to your advice and I enjoy you covering these nice old motors that have been modified by many people so there’s lots of trial and error to go by.
to be honest, just oversize the stock heads valves and port the heads, and do a distributor delete and run coils. use dome or dual valve relief pistons, and a mildish cam and your good for 350+ HP
Yea this was the answer to those issues back then.. but with the price point it became inferior and made more sense to upgrade to an LS based engine altogether and be happy
@@nitomeanboyGBODY I mean yeah but there are people, like me, who want to make a build more unique and everyone’s done an LS swap from LS swapping older cars to literally throwing an LS in a go kart, smart car, and pretty much anything and everything people got their hands on and it’s just kinda stale, plus you can make the same amount of power with a vortec 350 that you can with a 5.3 or 6.0
THIS WHY EVERYONE I KNEW WHO HAD AT LEAST BOLT ON'S WOULD ALWAYS INSTALL A MSD IGNITION. IT WAS ONE OF THE 1ST THINGS YOU DID IF YOU BOUGHT A Z28 OR TRANSAM. WAS REALLY HAPPY WHEN THE LS1 CAME OUT BC GM FIXED ALOT OF THE DESIGN FLAWS INCLUDING THIS AND THE SIAMESE EXHAUST PORTS ETC.
The only Chevy motor that I left intact. Not the TBI 5.7, or the broken pushrod from a bad roller rocker on the LS1 predecessor, or the recent LT 5.3 DI 5.3. My LT1 went until the body rotted.
Can swap to a LS style ECU and individual coils like a LS. Also, the LT1 heads’ ports and chambers were adopted to later SBC. They are the “vortec” heads (like on the L31) on the later 350s in the trucks.
Alright. You win. I want longform content where you bring us up to your level of understanding, one in depth tutorial after another. I would Super Thanks all on that series.
This guy covers it good !! LT1 was no joke. Member the reason they couldn’t make Crazyhorsepower cars because insurance companies back then wouldn’t cover anything more than like 250 hp without an act of Congress
I been lucky. I'm going on 12+ years of having my 96' Impala SS and she's been bulletproof (with the exception of having my 4L60e rebuilt 3x) and my Opti straight, got the MSD, and I regularly check my waterpump for leaks. I'm thinking about converting it to coil overs.
@@coreysharp9794 B-bodies weight 600lbs more, without having 5 passengers & a huge full trunk. With aggressive driving the 4l60e doesn’t last super long. You may also be lucky with yours.
@@coreysharp9794 Haha. I had two LT1 B-bodies when I was younger & had low mechanical sympathy. Both needed trans rebuilds. The ex-cop car (9c1) was ironically stolen. Recovered wrecked with stereo missing, but nitrous tank intact. They left me with a couple grape blunt wraps & an empty 2-liter of strawberry drank. I now have a ‘96 LT4 Corvette. Much faster than my nitrous’d 9c1, with a bulletproof ZF gearbox.

I literally walked into my friends dad's shop, and I told him I got a 95 firebird, and he instantly walked over to his desk and handed me that MSD ignition and told me buy this off of me you'll thank me later lol
Not sure what F*** most of what you are talking about is or does but you make it sound interesting and entertaining (i am not necessarily a motor head..but love cars..hp power caddilacs to be specific).thus I will continue to watch and learn at opportunity.. (-:..
Currently have a '94 LT1 with 280 original miles. Wire harness, computer, all accessories, still has the belt on it. Its available for purchase. Never even burned the undercoating overspray off the manifolds. Come get it!
Had a bunch of ex-cop cars with these back in early 2000s. Super fun cars. Sideways at every intersection. Beat on them relentlessly. Never an issue besides one of them having the leaking water pump, optispstk issue. Not to hard to fix.
Another thing to add if you’re going to change to the MSD distributor there are two different versions of the opti spark 92 and 93 had its own so you would have to modify things to make it work, 94 to 97 You can use the MSD without modification because what happens is that the water pump will leak onto and or water will seep underneath the distributor cap and have nowhere to go so the moisture stays in there take the cap off drill a hole at the bottom somewhere. Attach a vacuum fitting to the distributor cap and run a hose somewhere else to make a outlet because the movement inside the distributor will allow it to get dried out but you have to have a place for the water to go these engines are awesome, granted they are a bit expensive to modify because they were only out for six years and only were in certain model cars in all honesty, not all LT1’s are the same B and F body were for the most part because of them having 2 bolt main’s the Corvette LT1 was its own because it was the only one with 4bolt main’s from the factory unless the engine was replaced by the dealer because all replacement engines were 4bolt’s, and the corvette had the most horsepower and torque until GM did a one up to that and made the LT4 in 1996
Did a tune up on this motor in a 95 roadmaster sedan... loved that car, the only car i loved more than that was my 76 Fleetwood 60special brougham. Also had that motor in a 91 caprice classic and a 95 caprice classic. Its basically the corvette motor without the chip
Yo I feel this bro I got an all blacked out chevy impala same year and trim all blacked out tinted windows I had the mufflers and resonators deleted and straight piped it. Next I think I need to replace the factory air intake then get an E85 tune. Only thing is these cars weren't Designed to be race cars yes they are fast but I don't think there's actual engine components for it to replace and get more power. But hey I could be wrong I've just been doing small things to her
I had a '93 Formula 6 speed with the LT1. Strong running car for the time. Unfortunately i went through the scenario he mentioned. The water pump went bad, and it took the opti-spark out with it. This was early-mid '00s, and the MSD opti wasn't on the market yet. I had to get one from the dealership and it was like $450 .
the important thing with the optisparks is does it have the Mitsubishi optical sensor . i had a brand new remanufactured ac delco optispark. and it did NOT have the Mitsubishi sensor. so i took apart the old one that did swapped it to the reman one black rtv on all the seal points on the optispark housing. and locktite the 2 super tiny screws on the plastic rotor. should be good for another 20 years and runs like a top
May optispark was tuff to diag too. I had a 94 firebird (pre 98) so old ci.puter kept reading hi resolutions. Car would start, run, stall after about 10 mins. Not start again til next day. Opti spark was the issue.
Optispark and water pump was the first thing I changed in my 95 Fleetwood. I embarrassed a lot of people on 17 inch Daytons and Vogues. lol Never had any mechanical issues

I swear the 9C1 Caprice with the LT1 had a different tune from the factory compared to the Impala SS. I used to beat my friends 95 Impala SS every time by 1.5 car lengths with my 95 Caprice 9C1. We both had the LT1 and both had same mods (air intake, headers, and 3.73 gears), yet I always pulled on him for some reason lol.
I built 2 yrs ago that makes 1575 hp I used torque head as a replacement for the opti and holley terminator max built a custom gear ratio 4l80 with a trans brake 410 gears and 35lbs of boost. My advice is have the block machined and put together and splay to a 4bolt main caps this thing is a real monster
If You carb these engines they become MONSTERS with the right cam heads setup !
Yes I have mines carb in a c1500 .
At almost 5k in upgrades might as well ls swap it 😂
I truly believe don't nobody love cars more than you the vast amount of knowledge you have is passion driven in my opinion your one step away from what ever you wanna do in the car industry
Dab some in weld in the weep hole of the water pump. My opti been dry for years
You only need an aftermarket opti for anything before 96
*95
You know your stuff it’s entertaining to listen to your advice and I enjoy you covering these nice old motors that have been modified by many people so there’s lots of trial and error to go by.
to be honest, just oversize the stock heads valves and port the heads, and do a distributor delete and run coils. use dome or dual valve relief pistons, and a mildish cam and your good for 350+ HP
Yea this was the answer to those issues back then.. but with the price point it became inferior and made more sense to upgrade to an LS based engine altogether and be happy
@@nitomeanboyGBODY I mean yeah but there are people, like me, who want to make a build more unique and everyone’s done an LS swap from LS swapping older cars to literally throwing an LS in a go kart, smart car, and pretty much anything and everything people got their hands on and it’s just kinda stale, plus you can make the same amount of power with a vortec 350 that you can with a 5.3 or 6.0
@@matteblackexterior I respect it
LT1 love!!!
Finally sum lt1 talk!! 💪🚗💨💨😎
THIS WHY EVERYONE I KNEW WHO HAD AT LEAST BOLT ON'S WOULD ALWAYS INSTALL A MSD IGNITION. IT WAS ONE OF THE 1ST THINGS YOU DID IF YOU BOUGHT A Z28 OR TRANSAM. WAS REALLY HAPPY WHEN THE LS1 CAME OUT BC GM FIXED ALOT OF THE DESIGN FLAWS INCLUDING THIS AND THE SIAMESE EXHAUST PORTS ETC.
The only Chevy motor that I left intact. Not the TBI 5.7, or the broken pushrod from a bad roller rocker on the LS1 predecessor, or the recent LT 5.3 DI 5.3. My LT1 went until the body rotted.
I’ve had two LT1’s!! Damn Good Engine!!
Can swap to a LS style ECU and individual coils like a LS.
Also, the LT1 heads’ ports and chambers were adopted to later SBC. They are the “vortec” heads (like on the L31) on the later 350s in the trucks.
Alright. You win. I want longform content where you bring us up to your level of understanding, one in depth tutorial after another. I would Super Thanks all on that series.
Blessing folks with great information 💯
This guy covers it good !! LT1 was no joke. Member the reason they couldn’t make Crazyhorsepower cars because insurance companies back then wouldn’t cover anything more than like 250 hp without an act of Congress
I been lucky. I'm going on 12+ years of having my 96' Impala SS and she's been bulletproof (with the exception of having my 4L60e rebuilt 3x) and my Opti straight, got the MSD, and I regularly check my waterpump for leaks. I'm thinking about converting it to coil overs.
Damn why so many trans issues. Mines got 166k never touched. 93 z28
@@coreysharp9794 B-bodies weight 600lbs more, without having 5 passengers & a huge full trunk. With aggressive driving the 4l60e doesn’t last super long. You may also be lucky with yours.
@@SereneSpeed valid points. I've never seen one without at least 5 people in there with a haze of smoke.
@@coreysharp9794 Haha. I had two LT1 B-bodies when I was younger & had low mechanical sympathy. Both needed trans rebuilds. The ex-cop car (9c1) was ironically stolen. Recovered wrecked with stereo missing, but nitrous tank intact. They left me with a couple grape blunt wraps & an empty 2-liter of strawberry drank. I now have a ‘96 LT4 Corvette. Much faster than my nitrous’d 9c1, with a bulletproof ZF gearbox.
@@SereneSpeed dammmit!!! LT4 is the best motor chevy ever produced to date imo
The under dog! My favorite engine!
😂 you the man! You should be making millions of dollars. 💯 for the "Black Car GURU! make it work got dammit, make it work 😊.
They are good engine I got one in my 86 1500 with carb hei also an it work .
He's actually 100% spot on it's kind of wild that Chevrolet being a pretty damn dependable system with that HEI they had would do something like this they should have just put a crank trigger on it
I have a 94 trans am with long tubes and koni shocks and it’s lowered. I replaced the opti with a Petris opti and 3 hrs in with no issues
I know your talking about making it fast shiit I wanna make it reliable first.... but I'm still grabbing that cam too I mean..... 😏
Damn bro I used to own a 96SS Impala. It definitely had that problem
but one of the real problems is the water pump Drive seal another good thing to do is just run an electric water pump in the stock water pump housing
Opti delete is the best option for this car
Actually Mr. Gruru... there's a LS conversation kit that allows you to have individual coils. Just like on all LS engines.
That optispark was hell 😂
I know 3 ppl that tried the MSD opti. All 3of em had problems. Went back oem
Ive heard pretty mixed reviews of msd too. More bad than good
Dr.opti spark has a Nice setup
i like your knowledge my man. wish i had some of that. some day when i get the time I'm gonna build a chevy V8. don't know what I'll put it in, ill figure that out later
I literally walked into my friends dad's shop, and I told him I got a 95 firebird, and he instantly walked over to his desk and handed me that MSD ignition and told me buy this off of me you'll thank me later lol
As an impala owner, he ain’t lying lol
Not sure what F*** most of what you are talking about is or does but you make it sound interesting and entertaining (i am not necessarily a motor head..but love cars..hp power caddilacs to be specific).thus I will continue to watch and learn at opportunity.. (-:..
Currently have a '94 LT1 with 280 original miles. Wire harness, computer, all accessories, still has the belt on it. Its available for purchase. Never even burned the undercoating overspray off the manifolds. Come get it!
Where are you based out of?
@@marshalldang2605 Seattle area Wa state
Had a bunch of ex-cop cars with these back in early 2000s.
Super fun cars.
Sideways at every intersection.
Beat on them relentlessly.
Never an issue besides one of them having the leaking water pump, optispstk issue.
Not to hard to fix.
It's really a Mitsubishi Electronic Hall-Effect Trigger Ignition
Another thing to add if you’re going to change to the MSD distributor there are two different versions of the opti spark 92 and 93 had its own so you would have to modify things to make it work, 94 to 97 You can use the MSD without modification because what happens is that the water pump will leak onto and or water will seep underneath the distributor cap and have nowhere to go so the moisture stays in there take the cap off drill a hole at the bottom somewhere. Attach a vacuum fitting to the distributor cap and run a hose somewhere else to make a outlet because the movement inside the distributor will allow it to get dried out but you have to have a place for the water to go these engines are awesome, granted they are a bit expensive to modify because they were only out for six years and only were in certain model cars in all honesty, not all LT1’s are the same B and F body were for the most part because of them having 2 bolt main’s the Corvette LT1 was its own because it was the only one with 4bolt main’s from the factory unless the engine was replaced by the dealer because all replacement engines were 4bolt’s, and the corvette had the most horsepower and torque until GM did a one up to that and made the LT4 in 1996
Msd has been top dog of ignition parts and systems FOR EVER
Did a tune up on this motor in a 95 roadmaster sedan... loved that car, the only car i loved more than that was my 76 Fleetwood 60special brougham. Also had that motor in a 91 caprice classic and a 95 caprice classic. Its basically the corvette motor without the chip
I had a 95 trans am pro am 3 . Was a great car all except that optispark .
I have a 94 Z28 with the LT1 T56 combo. Not a bad ride but you were spot on about her problems and flaws . That and the interior was shet.
My favorite of this is the CAMMASTER that Mr Regular reviewed.
Cool videos.....can u do a video on a 2012 chevy impala ltz 3.6 plz thxs
Yo I feel this bro I got an all blacked out chevy impala same year and trim all blacked out tinted windows I had the mufflers and resonators deleted and straight piped it. Next I think I need to replace the factory air intake then get an E85 tune. Only thing is these cars weren't Designed to be race cars yes they are fast but I don't think there's actual engine components for it to replace and get more power. But hey I could be wrong I've just been doing small things to her
Ive had a 94 and 95 caprice and have a 96ss right now never had a problem wit the opti
Thank you bro, taking notes. 💯
For a second I thought it was Mos Def with a southern accent
I have 1 n my 1995 c91 police 🚔 car 🚗 very fast no bullshit
my stock 1996 lt1 never had any issues. granted it only has 13k original miles
All you need is the aftermarket optispark replacement and your good
This man is the Katt Williams of Cars
Thank you guru!!
LT5s r the gem tho especially in da 93”zr1
I had a '93 Formula 6 speed with the LT1. Strong running car for the time. Unfortunately i went through the scenario he mentioned. The water pump went bad, and it took the opti-spark out with it. This was early-mid '00s, and the MSD opti wasn't on the market yet. I had to get one from the dealership and it was like $450 .
the important thing with the optisparks is does it have the Mitsubishi optical sensor . i had a brand new remanufactured ac delco optispark. and it did NOT have the Mitsubishi sensor. so i took apart the old one that did swapped it to the reman one black rtv on all the seal points on the optispark housing. and locktite the 2 super tiny screws on the plastic rotor. should be good for another 20 years and runs like a top
YO , i been for someone too speak on the LT1 , goos job boss !! !! !!
Opisparks also need a passive ventilation setup.
Bro i learned more about cars from u than my dad...dam tbcg is my new og😂🎉💯
Had a 95 caprice, ran pretty good after it was rebuilt. But those exhaust manifolds weee also know to leak towards the back. Stupid ticking 🤣
Might be something to think about for a 1994 to 1996 Impala SS 🤔
Boy I hated changing those distributors.. but long live the baby lt1 (4.3s) and true lt1 🙌🏼🖕🏼
May optispark was tuff to diag too. I had a 94 firebird (pre 98) so old ci.puter kept reading hi resolutions. Car would start, run, stall after about 10 mins. Not start again til next day. Opti spark was the issue.
Sorry about the typo. *computer
Optispark and water pump was the first thing I changed in my 95 Fleetwood. I embarrassed a lot of people on 17 inch Daytons and Vogues. lol Never had any mechanical issues
We need more information on the lt1 sir
