Carb and intake for cowl hood

[1st_chevelle]

Man I am so sorry for not replying to this thread with everyone's advice and for now digging up a 5 month old dead thread. What I am truly worried about is fitment issues with the cowl hood. I paid extra for this and I'm keeping the hood. Do most combos fit without issue or am I worried about nothing? I've been searching for the last few months and I've been saving when I haven't been buying my pistols. In an unrelated note the guy who built it (and it's my fault for not checking) decided not to grease any of the new bushings and now they're all shot. I've got a busy an expensive summer.

A high rise intake and really any 4 barrel carb will fit under a cowl hood. Now if you're trying to fit a stock cowl induction air cleaner on top of it that may be a problem. I have a 454, high rise aluminum intake, GM version of the Edlebrock RPM Performer and Holley 770 carb. On top of that sits a 4" high 14" diameter open side air cleaner.

I could care less about the stock air cleaner at this point. Hank thank you that is the best answer and the best info I could have hoped for. Where did you get your parts?

Engine is a GMP 454HO crate engine. It comes with aluminum high rise intake. Carb is Holley Street Avenger, my son got it with his discount when he was working at an auto parts store. I know, no help to you. Summit or Jegs have good prices, they're both usually the same price for the same part. I would start there.

Same here. '70 Chevelle with cowl hood. 541 BBC and 1000 cfm Dominator with big old air cleaner. Lots of room!

The one thing I'm torn about is Holley vs Edelbrock. I like Edelbrock's intakes and Holley's carbs. It's such a hard decision.

[jpekarek]

Use the one you know best. They can both be tuned to provide great performance. Holleys are very tunable and streetable. Eddys are also very tunable but many people don't know how to tune them right. They say they will run right out of the box, but this is just a starting place. ALWAYS adjust your floats before running the new carb, they are never right on any carb.

[Hank70SS]

No problem running an Edelbrock intake and Holley carb. In fact that's pretty common. As jperkarek said, go with the carb you're most comfortable with. It will need tuning, so the one you know is the one to go with. They're both good.

Thank you gentlemen. I've been leaning toward Holley but I still know JACK about carbs. No idea how to tune or really use them to be honest. I've had my car since July and I've spent a majority of that time in Germany. Now i'm in Kansas waiting April so I can drive back to Indiana and trailer it to the new place in Kansas. I've spent so limited time with it I barely know how it is. I want to do the carb and intake myself which is easy enough but tuning is a whole new ball game.

Alright got it nailed down to a Holley 770 Street Avenger and an Edelbrock RPM Air-Gap. I already have a mild cam installed. I want it more for breathing room so I don't have to re buy parts. Thoughts?
