What manifold and carb do you recomend?

[ChiefJones]

So...I have 2 70's I am doing, the second that I am not working on right now has an engine that is all set, the first had a 327 2 bolt main that had some work done to it. I was just going to throw it back in after removing it and cleaning it up but one thing lead to another and I had it rebuilt, after I dropped it off It dawned on me that I had a 4 bolt 350 block laying around so why not use it...so...what I ended up with is a 4 Bolt 350 block bored 30 over with a cam and double roller timing set but with the 327 Crank which I was told is a higher rev crank..right now it has a stock Chevy 4 barrel spread bore manifold. If all that makes sense what do you guys think I should think about putting on for an aftermarket manifold and carb make and size??

I would be nice to know what cam and rear gears you are running. Monty Carlos are heavy, I would go for a small carb (600 CFM) and a dual plane and go for torque.

I would have to agree with Mike, with a 327 (.030 over); 600, maybe 650 holly DP would work good with an Edelbrock air gap dual plane.

Also Holley has a great site for picking out a carb.

 

The air gap is a perfect manifold for the job but I would say you want a vac sec and not a DP. Holley recommends a VS carb for heavier cars with a mild motor.

I agree that a vacuum secondary holley or a eddy style with the secondary air valve is the way to go.
