Those kinds of threads do tend to be pretty quiet. lol
Good thing the OP cleared it up by saying he can modify it in his class.

If your running FAST and all they're worried about is it appearing stock could you have a composite mold made of the top of the intake then lay it over and attach it to a better performing aluminum intake?

Mark, thanks. It can be an NHRA Stock carb. I was gonna try to run a 409 400 hp AFB carb as it's bigger then the 327 carb
Why not a 780 or 850 cfm Holley? Both are carbs listed for NHRA Stock engines.

It would be for a 1962 or 1963 327 300h.p. combo. Can't run a Holley. Has to be an AFB with the 459 intake.

Run a large AFB like the one that came on a 67 440 GTX, it has the small airhorn so it will look stock and yet flow at least 100 CFM more than a 409 AFB.

Thanks Paul. Have a list number for that carb. Thanks.
