i have a sb 305 with 58cc h/o heads, a summit cam (224/234 duration),(.465"/.488" lift), and i would like to know what intake and carb would be best suited for this setup??? really would like to maximize the power...

Where are you use it on? Are you going to race it or street use? What transmission? What gears are you using on the rear end? How heavy the car is going to be? All this will determined what carb and manifold you are using. Don't except a lot of horse power out of 305.

77 nova, street use, 350 tranny, stock gears to change later

[lg1969]

the 350 tranny, are you using a stall converter in the near future?

You could save some money by dropping a stock type cast iron intake manifold on there along with a Quadrajet that's in good shape.

Although a shiny new Performer intake and Holley 600 vacuum secondary looks more hot rod, it won't make a whole lot more torque anywhere in the RPM range compared to the carb & intake that you could grab from a wrecker for really cheap.

That money could be better spent on a limited slip 3.55 axle later down the road...

Come to think of it, in the U.S they had factory aluminum intakes in the 80s, we Canucks didn't get them as far as I know. That would be better yet.

I agree with a vacuum sec 600 Holley. I was thinking of Edlebrock Torker single plain manifold. His Nova is fairly light car. The cam he is using is more of midrange cam. I would use 373 gears. I would use a 3000rpm converter, because 305 does not have to much torque

this is my first build so i dont wanna sink alot of bucks in this one, but i have planned to go with a summit stage one intake with egr, 2500-2600 rpm stall, 600 cfm edelbrock, 1 5/8 primary to 3 in. collecter headers, b/m shift kit, and 3:73 gears... i plan to build a 383 stroker next, but thats a whole different plateau.... ??? should i go with bigger primarys???

1-1/2" or 1-5/8" Primaries, No larger with a 305. Unless it's an all out Drag engine. Why the EGR mainifold?

[impwerks]

it came stock with egr and i really dont know if i have to go back with it or not

[impwerks]

what could i do to make this an all out drag engine????

Before you spend a nickel I would suggest you buy one book that I wish was around before I started pulling the stock 'junk' off my first car and replacing it with aftermarket parts: Budget Building Max Performance Chevy Small Blocks by David Vizard.

You can get a lot of similar info from some of the veteran wrench-pullers on this forum, but here is a lot of quality & objective advice packed into one book, and it's all about the SB Chev, plus he's not trying to sell you anything (other than the book!)

Seriously, buy the book and you won't be disappointed. He'll save you making many mistakes I (and a million other kids trying to hotrod their rides) made.

EGR valve is not needed. You are using a different carb. I used a Carter AFB carb with a dual plain intake without the EGR on a 77 Buick Skylark with a 305 and it ran pretty good for me. Since the car was very old it only needed safety inspection.
