i searched and did not find an answer to this

i have yet to choose which of the many wonderful small blocks that gm offers for my v8 swap, but i couldn't help but notice that i have a functioning hood-scoop (for the intercooler) on my turbo'ed '89.

if i run a carburetor on a v8 will i be able to use the existing hood-scoop or will the carb stick up too far?

i would like to use a carb because i am used to tuning the carbs on my racecars. and it would be so much simpler. so if the carb won't clear the hood, it would be a deal-breaker for the carb motor, and would help me in the selection of a motor

thanks ahead of time guys

All of the carb'd V8 swaps I've seen have had a hole cut in the hood (I've only seen 2 or 3 though). maybe you'll be able to get away with it with no air cleaner, but that's just too risky.

It has been done...

although I highly suggest going LS1 or LS2

im sure it can be done with enough ingenuity, but as sunbrn said, an LS-series motor would probably the best route, they are the most documented anyway

A carb'd V8 would be so much cheaper and easier though. Since there's no EFI and alot less sensors and whatnot, it's just drop it in (with about the same amount of fabrication as an LS series) and start.

no way, check out the v8 rx7 forums. theres lots of threads on this forum and others on the subject.

can somebody just answer the question instead of getting off the topic and talking about the advantages of an ls?I have a 350 with a carb and I wanted to put a t2 hood on but I'm worried about the scoop's offset and if it would accomdate the carb

the plan was actually to use an ls1 but still use it with a carb, not for price but for simplicity, and actual power....i know that a lot of people will disagree but in my late-model f-body experience, you can get as much power (or more) with an ls motor by using a carb. and better yet without having to upgrade injectors, or having to re-program an ecu to change timimg, or fuel curves (which contrary to their own opinions most individuals can't even do very well, and i'm no exception) and without needing insane high-pressure-efi fuel pumps to get enough fuel to accomodate the type of camshafts i run, (and lots of nitrous too)
.......best yet the ls engine's intake manifold runners are so long that it hinders high-lift/high-duration camshafts high rpm power, so a single plane carb intake manifold is the only option.
i also build my motors to make power at rpms so high that an ls1's ecu can't run sequential injection so a costly stand-alone computer would be required

.......anyway, to make a long story short cost is not my only reason for going with a carb, once the motor is in i will modify the hood (or just buy a new cowled one) but i was just hoping that i could use the factory hood-scoop to maintain that "sleeper"-look

I'm just saying, with a carbed V8, there's no ECU to worry about wiring up, and less electrical to deal with. The one with the carb will just run no matter where it is. Since the V8s are shaped basically the same, the amount of fabrication will be similar, just wthout all the wiring.


And to answer the OPs question; No, it will probably not fit with the stock hood. All the carbed V8 FCs i've seen have had a big hole cut in the hood to accomodate the air cleaner. Like so: http://www.youtube.com/watch?v=UDnmQCtpaJM

it's what they do! i've been dealing with them lately for a '85 sbc and they're great!

You'd need the lowest intake you can get and then a pretty thin air cleaner.
I'm trying to get my hands on a TII scoop to see if it will cover the carb on mine. I have a taller intake and that put the top of the carb right at the level of the outer hood skin.

if your stuck on this idea, i wont try to change your mind, but as for the hood, you could cut a hole out for it and then use one of those big "universal" scoops? just attach it to the hood and leave it (like a race car) or smooth it over with bondo and repaint the hood?

im doing the same thing as you are......for the same reasons......f the ls series..i like it,,its too expensive to maintain,tune etc


look into a low rise intake manifold,i believe edelbrock make some,also look at that triangle looking air cleaner(also edlebrock)...if you get the granny speed shop kit,id just say brining it to a decent welding shop can chop it down about an inch or so

I agree with the gen1 being cheap, but the gen 3 engines are too. Just not the fancy aluminum block ones
I just got a LM7 Longblock (iron block 5.3) for $300. You can find the 6.0 iron block engines for about $500

You might want to try using a factory style air cleaner setum from an 83 to 85 5.0 Mustang. They sit way down over the carb. It might help.
