I finally got my vortec swapped in, all the same except I got a slightly more aggressive cam (204/214 at 050 with 450/450 lift) and Flowtech headers. I was able to reuse my distributor, it had a melanized cam gear on it from the factory which was awesome, same as the distributor that came stock in the vortec. Still got a bunch of piddly stuff to do, I was able to find a water pump for a TBI truck that had the extra hole on the left side, so I didn’t have to plug that hole up and I don’t need a bypass because of it. I am able to run my heater core hose straight to the water pump because of that. Although I may have 3/4 NPT fittings on my water pump, I will find out when I go buy some to complete that. Just need to get the starter motor back in, finish up the cooling system, get it timed, and get my tune from Harris Tuning, and still waiting on my custom TBI from SPR Performance.
@@19jody72 got it all back together. I forgot that my l31 block had holes tapped for an oil cooler, so I had to put that on a loop. Lost 4 quarts of oil when I started it the first time lol. Truck is running though, but the stock tune does not like that engine at all. Waiting on my tune from Harris Tuning, and I have to put in my new TBI from SPR Performance and my high pressure fuel pump. Got it running last week, but got the timing dialed today. It idles really nice.
@@iDrive4fun93 Thanks man for the update.. "thinking" on going this route.. just a daily driver.. I'm done with drag racing and wasting money on broken parts.. just want a nice daily now
@@19jody72 I will update once I get my tune, and my new tbi and fuel pump on. Right now it idles really nice, and slow acceleration is fine, but give it a little gas and it bogs down and wants to stall out. It feels like a fueling issue, so hopefully the newer tbi with bigger injectors, higher fuel pressure, and the high pressure fuel pump will do the trick.
I did a vortec engine swap on my 95 obs, and I can definitely tell an improvement in torque. It runs decent, but the idle fluctuates, and has a hesitation and bogs on acceleration once it's warmed up. I know it's not a timing issue. I believe I may need to get a chip.
I think it’s a stage 2 chip if I remember right, the truck has a “bigger” than stock tbi cam. (Stock Vortec cam which is .414/.428 lift compared to the tbi’s .395/.408) it also has a carb intake so you could probably push for a stage 3
Years ago I did the same swap on my '93 with a mild Comp hydraulic roller. Mine ran okay but never quite right, I could not figure out if it was the cam(which was supposedly TBI compatible) or the fact that I live in a cold climate above 7000 ft. elevation. Does yours run as smooth as stock? Thanks!
Hi, it kind of does. The issue is when I put this truck together it was hurriedly and I had to use what I had around me. I used a tbi unit from an 87 c10 truck and without the chip the idle was kinda funky, and it would pop and backfire under heavy throttle. I used the jet performance stage 2 chip and it helped significantly. I want to do this swap again on another truck but do it in a better way.
@@_chevy_stepside Thank you, unfortunately Jet doesn't make a chip for the tbi with the 4L60e. I sold my truck and replaced it with a '93 Yukon, leaving the engine stock after the headaches I had with the last truck.
It’s a complete 97 Vortec 350 long block, never did anything internal to the motor at all. I did was swap the intake and the front accessories to the tbi front accessories and a carb intake. It’s stock Vortec stuff
Run one line to the radiator, other one to a port on the intake manifold. I believe the larger one is the one to run to the radiator if I remember right
Hello there, i have an exact same pickup that you imported from califonia 3 years ago. it has been running like clockwork but now started to have problems. it stops all of a sudden and it can be started right after, but now I don't dare to drive any longer. I have changed the ignition module, spark plug, distributor cap, rotor, and fuel filter. can you help me! What is wrong?
I’m doing this right now. Just installed Edelbrock 2716 intake and adapter. Found this video looking for more info on the throttle bracket, glad to see it works. My question is when you removed the EGR from the system does it throw a code? I was going to get a new chip to have it “deleted” from the system so it didn’t but was curious if yours did once it was removed physically from the system.
From what I know if it's ODB1 then there should be zero code or performance change, ODB2 should throw a code but I'm not sure about performance. Someone out there can tune it out if so.
I have a 95 Chevrolet c1500 4.3L vortex. I believe it's already a tbi and gonna swap for a 350 tbi. Shouldn't be to hard. Should bolt right up besides the mounts
So I’m actually going to answer some questions on this truck when I go back to Texas this summer. For a more accurate idea of how to run the heater lines, check out my video “How to Carb Swap an 88-94 Chevy Silverado” and you’ll be able to see the heater lines in the background and how I ran them with the bypass. It’s virtually the same way
@@_chevy_stepside good deal. I’ve watched all these videos a few times over but I will watch it again and pay attention to that. Plus I am subscribed and have notifications on. You got the best videos for this kind of stuff and for vortec swaps.
I appreciate the kind words, I’ll explain it on here, basically I ran my heater lines kinda like this (I’ll do my best to explain this through text) I ran the one on the left side (looking straight at the heater fittings) straight to the radiator like factory, the right side goes up to the front of the engine, into the intake on the passenger side on the front (with a Barb fitting and hose clamp), then the bypass is ran just like in the video. Hope this helps
In the previous video you said you had a Corvette l98 distributor. Did you change it? Because in your description here it says TBI distributor with hardened gear
I did, that distributor went bad like 3 days after filming the first video, so I took the gear off that corvette distributor and transferred it to the tbi distributor. Been running fine since
So I bought a vortec engine pulled from a 1 ton recently, getting it ready to swap into my truck. I am keeping the tbi system, and getting a bored tbi made for me with the cop car injectors. Do you have a part number for the melonized cam gear so I can re-use the distributor?
You could probably get away with it, the donor motor I got didn’t come with a distributor so I used an old L98 TPI corvette one that I had laying around. But it would probably work, I’ve just never used one personally.
I just a '97 vortec into an '89 K1500. It's running rich and sputters a lot. I've chased every vaccume leak, and changed most sensors. Any ideas for me? Also did you have to get the Jet chip programmed? Do you have a link? I'm so frusterated I'm about to slap a carb on it!
I also had the same issue when I did a vortec swap on my 93 obs and the issue was that I had a v6 4.3 before the swap so I put in a 350 ecu computer and it fixed the rich fuel issue
Do you have to change the spark gap? The vortex use like .65 gap but the tbi 350s ignition system used .35 so do you change the gap for the tbi ignition system or leave the plugs gapped at what the engines usually use?
I left it alone. The thing is, the Vortec trucks use a different style ignition system than the tbi (don’t quote me on this but I believe it’s a similar style to the optispark system in the LT1’s). When you swap the tbi back on, you’re basically putting tbi parts on a Vortec engine, I left the plug gap at whatever the Vortec plugs came with and had no issues whatsoever
I put a 5.7 vortec crate motor in my 95 z71 4x4 and went with the original tbi set up and distributor est. Set base timing at 0. Truck starts great but under a load cuts out and pops thru throttle body sometimes dies out. What chip did you install to stop this problem?
Hey bud, looking to swap a vortec long block into my 87 square body R10 (first year of TBI). Did you have any problems with not having the EGR? I was curious if your ECM would be throwing codes for the EGR unless you found some workaround. Thanks
The ecm does occasionally does throw a service engine soon light as you’re driving along but then it goes away as soon as you shut the truck off. Only happens if you drive it like 50 miles or more sometimes.
No sir that’s for a quadrajet intake. The only adapter I could find that looked remotely close was Holley 17-45 which is for a square bore intake flange (which is what I used).
Most of the Vortec motors came with 4 bolt mains. To be honest unless you’re pushing for like 450+ hp it doesn’t matter if it’s a 4 bolt main or not. Some do and some don’t.
Sounded get! Just left another video of yours asking about making a video on the truck running to hear exhaust on it. I think I read it had flow master on it but I didn't recognize the series. Would the 40 or 44 make the sound quite a bit different? I've always liked that lower tone sound that the 40 or 44 type has. I hate how people get in the comments of UA-camrs videos and try to tell them how they did something wrong and how they would of done it. Some things and prices are different sometimes and there is other ways to do stuff but no need to be rude about it. Keep making the great videos and don't let them get to under your skin. I know I would be mad and wouldn't stop thinking and over thinking about it! That's why I wouldn't do good at making videos!
So on the red truck it has true dual Flowmaster FlowFX which are knock off magnaflow mufflers with stock manifolds. My black truck has the Flowmaster 40’s on it. The 40’s are more raspier and make more noise than a 44. I appreciate that man! I try my best and build what I like, not what someone else does.
Sorry for the late reply, been tremendously busy with school. To be honest, I never kept track of fuel economy, on the factory tbi motor this thing struggled to get 10 mpg and the other thing is this is a 33 year old 4x4 truck with heavy all terrain tires, it’s not going to get good fuel economy. I returned it to the customer not long after I finished it so I never had a chance to track fuel economy after the swap. The power is definitely up, by how much I have no idea. But you can definitely feel it. Definitely runs cleaner and smoother than with the wore out tbi engine.
Great video with to the point information. I daily a 94 step side 2wd and love my truck. I’m thinking about doing the swap as well and I’m curious about the gas mileage. Did the vortec swap help? Btw I agree with your stance on the epa and emissions. Fuck em
To be honest with you man, I quit caring about fuel economy. These trucks are 25-30 years old now and you can’t expect great gas mileage from them. My guess is with the exhaust and all being a 4wd it’s probably getting around 12-15 mpg if I had to guess
Definitely. Haven’t dyno’d it yet to prove anything but it used to be this truck couldn’t get out of its own way, now it’ll roast the tires going into 2nd gear. The Vortec motors with the stock fuel injection make 255 hp compared to the tbi engine’s 210. The truck probably makes around 230-240 hp if I had to guess and a hell of a lot of torque. If you upgraded the tbi and threw a bigger chip at it, it would probably make more than that
@@_chevy_stepside using those slightly bigger injectors in a 46mm ported assembly would probably net some gains. Technically the stock TBI unit flows enough to support a little over 300hp, using the cfm calculator. The TBI definitely isnt the weakest part of the engine on the stock swirl port 350s. With the EBL from dynamic efi and a WB02 you could probably tune this around 275hp, a bigger cam and 1.6 rockers could easily put it over/around 300 with the stock tbi.
@@iDrive4fun93 This a customer’s truck who is over 65 years old. She’s not concerned in power so much as she is driveability. We’re probably gonna sell it later on maybe. Don’t know yet
I did the same swap with a carb intake and adapter plate. My truck bogs down and even cuts off some of you get on it from a dead stop. Did you install the jet chip after completing the assembly or before? Just wondering if the chip is the only thing I need. As bad as it runs sometimes I wonder if that will be all it takes to fix it.
I did it after, mine did the same thing but after I put that chip in if you lean into the throttle it goes like hell, if you stomp on it it coughs but then goes, tune could use a little bit or ironing out to be perfect.
@@_chevy_stepside yea but not sure .. so you half to buy carburetor intake that fit a 96-2002? And also adapter plater or not? Cause on the setup I see on amazon there is no need for the adapter plate
I agree with you on the GM TBI Performance Intake. WAY too expensive for too little performance gain. Thanks for the video.

Set the base timing at 0 degrees. Computer automatically advances or retards it at idle and as you rev
