ChiefJones Posted September 10, 2012 Share Posted September 10, 2012 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?? Quote Link to comment Share on other sites More sharing options...
Mike 57 Posted September 14, 2012 Share Posted September 14, 2012 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. Quote Link to comment Share on other sites More sharing options...
gjmike72 Posted September 19, 2012 Share Posted September 19, 2012 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. Quote Link to comment Share on other sites More sharing options...
Mike G Posted September 19, 2012 Share Posted September 19, 2012 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. Click here for Holleys carb finder site. Very cool! Quote Link to comment Share on other sites More sharing options...
Mike 57 Posted September 20, 2012 Share Posted September 20, 2012 I agree that a vacuum secondary holley or a eddy style with the secondary air valve is the way to go. Quote Link to comment Share on other sites More sharing options...
