A cross ram intake manifold on a big block Chevy? COOL!!! Normally, I see those types of intakes on those old Chrysler Hemis and Wedges. Looks and sounds DAMN good. Great job, guys.

Awesome!! Havent seen one of those since Pomona swap meet in the 80s. BB Crossrams are super rare Pure eye candy .Ignore the critics they are still playing video games piping in with thier expertise!
Never seen anyone break in a cam this way- starting and stopping several times, I’ve always heard let it run a half hour at 2000 rpm on first start. I like your way better. Seems safer.
make sure the pushrods are spinning first time it starts then run about 22-2500 varying it for 20 min. Starting and stopping is not a good idea at all.
I don't know how I got here. But i enjoy every single scene of this educative video. Yo bro! I need a good fairly used 454 for my Chevy 72 with 350 block.
That is a cross ram intake, it's been a while since we saw that intake but if I remember each carb feeds only 1 bank of cylinders and the carbs are 600 holleys
I'm sorry I told you about the dragster motor!!! This is that 427!! We put a howards cam in there I believe it was like .565 lift on the intake if you want the part number to the cam i can get it though. The heads were a smog head open chamber but we put dome pistons in it and i believe cr was about 10:1
You are correct! This engine went into a 37’ dodge business coupe with a lead foot behind the wheel so I’d assume he is constantly checking to see if it performs well. Thanks for checking it out!
Nice Job Guys 👦 l own one of these Manifolds here in Australia 🇦🇺 Would ❤ 2 put it on a 496 & drop it in a Beismeyer Flat Bottom V-Drive Boat . Do u have any idea how much HP & TQ on race Gas ⛽️ u guys will make out of Ur 427 Chevy . Thx 4 Sharing. Xcellent 🇦🇺
Those are what we like to call budget allumimum heads 🤣 a can of spray paint is much cheaper and looks good. But that is what the owner asked for so thats what he got
From the factory the extreme MOPAER 413 cross ram and race hemi, MOPAR also offered them for the street Hemi, which could have been preinstalled on hemi cars. The Chevy 302 cross ram was also OTC not factory installed.
Couldn't get a Crossram on a bigblock Chevy, but they did use them on a few 302 SBC Z-28 engines. Best bigblock Chevy was a 68-69 L-88 427. It came stock with an 850 Holley doublepumper on a highrise aluminum intake.
Why use vacuum secondarie carbs I would have went mechanical double pumpers twin 750's it looks cool but a single carb 1150 dominator and a dominator intake will make more horse power what do you plan to stick it in a 68-74 X body would be my choice
110 Octane Fuel . Gee guys what sort of HP & TQ Figures are u guys looking at with this 427 bbc . I have one one of these manifolds & have been considering a 496 or a 525 cu inch motor for a Beismeyer Flat Bottom Boat out of California. I reside in Australia. Nice work fellas
I believe the idea was originally implemented in the 60s on a Chrysler engine and then it was remade similar to this one for sbc and bbc by edlebrock. I could be very wrong as well. There is some history to it but no doubt the intake is definitely cool looking! Thanks for the comment!
These are 600cfm carbs but its been so long I have no idea what power valves or jets are in them. Really though, that's all up to what kind of power your making and what your engine is going to like the best
I sure hope you got a roller cam in that motor otherwise you're in deep shit, breaking a motor in at idle with a flat tappet ,I think you know better so it must be a roller cam.
2000rpm is not idle. We stated our break-in process in the video and then carried it out. We’ve Broken in many engines this way with no issue. Thanks for watching!
It looks like the old Edelbrock XC-96 BBC rectangle port cross ram from looking at it . I had one on a 70 LS6 that I put a bigger solid lifter cam that went into my 66 Chevelle SS 396 I had back in the early 80s . I had the Muncie close ratio 4 SPD with the 12 bolt rear positraction with 4:10 gears with ladder bars and it would pull the front wheels off the road with drag slicks on back . I bought the intake from my boss who sold it to me for 50.00 with the carbs and linkage and he used to run it on a modified dirt track stock car with a 427 for some years until rules mandate changed to only run small block engines back then so the engine came out and was sold but he kept the intake and used the money from the old car to build a new car for the upcoming season with a sbc with 180 deg headers that dumped behind the engine . I was at a car show a couple years ago and someone had the same intake with the carbs and linkage and they were asking 1,200 for the whole thing and the carburetors had to be rebuilt he said . I see these on eBay at times and they never go cheap and are fairly rare now so you don't see a lot of them being used much . Most guys drag racing now would rather use the tunnel ram or a big single plane intake because the single plane weighs less and are easier to tune and don't make all that much less HP because single plane high rise intake technology has come a long ways since the early days .
Honestly I forgot the numbers on it but it is an eddlebrock crossram with 4150 flanges. It does look pretty nice it was put into a 1937 Dodge Business Coupe.
Looks like the XC-96 with the rectangle ports from what I can see because I had one years ago on a 66 Chevelle SS 396 with a swapped LS6 454 that had a bigger solid lifter cam with big tube hooker headers on it and some other goodies .
...I had a cross ram on my 1960 VETTE gasser L79 , my high school ride,but still have a 427 like this one , only the manifold is polished and the 600 holleys are chrome.. looks a little goofy all shiny but sounds wicked..
Btw, do you use the intake baffle to keep the hot oil off the intake manifold and the windage tray in the oil pan to prevent the crank from sucking the oil up during high rpm?
Thx for getting back to me. Going 2 go 496 & after market block 4 my application.. Just some advice on CAMSHAFT SPECS. Apparently these manifolds require a few inhouse tricks. I will be running 11.1 comp. And hopefully Holley Snipper Carby's (Electronic). Or equivalent. MSD Ignition. I am looking 4 over 600hp. Going 2 put it in a Beismeyer Long Deck Flat Bottom.
Yeah the guy that we built it for has it in his car right now and it is running pretty good still some tuning yo do of course but other than that its good. We weren't planning on making a video of that car but is that something you would want to see?
Always "quick" response when there's NO torque converter or flywheel, clutch, pressure plate assembly! Or front drive assembly water pump, alternator, power steering, ect!
I'd like to build one for torque. My truck could use something better than the 366 it has. Frankly do not want to put money into the 366 especially if there are better options out there. Would like to see 550-600 ft lbs of torque. No more than 425-450hp
John Lingenfelter built an engine for his C30 Crew Cab strictly for towing. 9 to 1 forged piston 496 with stock but cleaned up port 781 heads, 260 Comp Cam, Performer intake with a 600 Holley and cast exhaust manifolds. Torque was 500 at a very low RPM. Don't recall HP but that was 30 plus years ago on pump gas. I imagine it was around 400. Bet you can most nearly duplicate that today.
@@bladenrexroth2555 Regular block 454 bored .060, .250 extra stroke. There are kits all over the place these days. Even though a tall 454 was made for a few years, it isn't necessary.

Why would you use a smaller package when the bigger one is the same price? If you make 1hp per cubic inch, you will lose about 25hp. In reality a performance engine is 1.3 roughly so a 427: 555hp 454: 590 about 40hp. Just to toss this in stroke the 454.... to a 496: 644
But also gotta remember that you can turn the 427 a little bit higher and it also revs faster and its just something different and pretty cool in my opinion. But it all comes down to the owner thats what he wanted so thats what we built him. We eventually wanna do a bbc stroker in the rear engine dragster.
@@moonshineperformance9135 literally no it doesn't. My 489 will out rev MOST 427s. That is like saying I should build a 327 because it will rev faster than a 350. NO, that is some myth that people use to justify building a 427 even though they had the parts available for a 454.

Hi Guys any idea of ur hp & torque figures. I have one of the beautifull old manifolds. Looking at a 482 or 496. Not sure if u can go bigger on the cubes due to block & head spacing. Happy 2 be corrected. Thx 4 sharing fellas
Well we would guess about 400-450 hp but that is also with a decent sized cam and 10:1 compression. Also this is a 427 so it is able to rev a little bit higher and faster. And I believe a 496 is a.030" over bbc with a stroker crank but with an aftermarket block you can go way bigger. But with a gm block you could take it .060" over but I'm not sure how many cubes that makes it
Hey bro... These manifolds are nice to look at and all but are a motorheads worst pain in the ass.. Any Big name Single plane would easily out perform those ..and leave you smiling when you need to adjust valves or attend to valve cover gasket issues . these are a headache not worth having...But then that's just me . I know a guy who loves the Hurst T handle even though when slamming 3rd it loosened and he punched the steel dash board breaking his hand .. He still loves that handle.. I personally would rather have function which is why I use the white ball.. Another reason We use Roller cams instead of Flat tappet. They flat out suck ...
We have to run them like that on the test stand because they won't clear the plate in the back so its just easier to throw them on upside down, unless it's a small block then we can use the zoomies from the font engine dragster

Yeah really its not a huge problem but they always fall off when you're trying to set the intake on so we just use rtv and it gives it a great seal.
That's why u glue them 1st with silicone in the corners. Otherwise a manifold blowback /misfire can blow silicone out completely

Needs a muffler...and I think those headers are on wrong
It was put into a vehicle with a complete exhaust.
Just kidding,haha. You all do some nice work and your channel just popped up on my recommended so I've been binging your vids, subed too!
We have to run them like that on the test stand because they won't clear the plate in the back so its just easier to throw them on upside down, unless it's a small block then we can use the zoomies from the font engine dragster
Thank you!!

I would bet someone painted the intake to do a port job instead of the blueing compound...Cheaper..........ugh
No he just didn't mask it. He used a gasket to do the port matching work
@@moonshineperformance9135 Are those oval port heads and sq port intake? How would one try and port match
Sweet CrossRam Intake!!!!!!!! Bitch'n!!!!!!
Self taught? Great job
Awesome 😎
Man that thing sounds plumb nasty bad to the bone.
Plentiful dates of population by personality .builders of engine history.
Chrome don't get ya home!
my favorite color is Chromium
Too bad you probably can't build a good tow rig motor with that cross plain intake
Never use chrome, retains too much heat.
NO
Those shorty headers are gonna kill ur horse power.
