I have a low mileage 74 coupe with the original 454 and I will be trying to upgrade the breathing capability of the engine and still keep the original hood.
Any opinions on what Intake/Carb. setup I can use.

well, I came in here to give some suggestions, but I don't have the big block.

So, instead I will just say

A BB owner will have to get this one for ya.

Just corious..do the 74 big blocks come with cowl induction such as on the small blocks in that year? Do you have a q-jet carb on there now? How about sending it to lars for a prep. The CFM rating of the q-jet should be enough to make a nice performance piece provided its set up right. if the 74 has a cowl induction hood factory. I would stick with a stock height aluminum intake to keep that all functional. Definatly loose some big time weight with an aluminum manifold. Gain some better flow characteristics at the same time.

Well your choices are very limited. If your keeping the Oval port heads then your choices for anything better are an L-36 off of a 68-69 390hp vette like I currently run, it's aluminum with spreadbore pattern so you can run your quadrajet with it. It's slightly better then your stock intake but it's nothing great as far a a performance intake, but it will save you a ton of weight over the cast iron one you have now. Your only other choice is a Torker2 which is a small single plane and has a squarebore pattern so you can run any holley, demon, etc. on it. Neither intake choice is the best, but there's not much that will fit under the stock hood. I'll be swithing mine over to a torker2, 750 mechanical Demon shortly, from my current L-36, Quadrajet Setup.
