I have a 289 with a 2bb carb , long tubes.h to flows(stock afterthat stuff).. I have Edelbrock Performer intake(2121) with matching Edelbrock Performer camshaft/lifters (2122) , These are still in the box and I am looking to get Performer carb to match the set up. My question is what size cfm should I get with this set up?
I know people are going to say why not go with the RPM set or something like that, but I have a 347forged shortblock that I am building up and with that engine I will go bigger and better. Right now I have these parts setting in the garage and was thinking that I should throw them on and when I sale the 289 engine I will let them go with the engine...

So long story short what CFM would be good , 500,600,650???? Also with the cam will i need to change the push rods?roller rockers??

thanks
