Power with this setup?

It's a 350 bored .060" over. 4 bolt main.
-Flat-top Pistons
-Stock Crank and Rods
-Vortec 062 Heads (64 cc Chamber)
-Edelbrock Performer Vortec Dual Plane Intake
-Quadrajet Carb
-Long-Tube Headers w/ Cat
-Stock Goodwrench Cam for now, undecided on an aftermarket one.

Help me out if I'm missing something?

Re: Power with this setup?

i would go with a .450ish to about a .470ish cam also throw that quadrajet in the trash and get a holley

that motor should scream...My firebird is .030 over with 4 valve flat tops, a .480 crane cam, bone stock heads off a 81 c10 350, 1.6 roller rockers,edlebrock rpm intake and a 670 street avenger, and the time is posted in the sign.....its amazing what a difference makes in flat tops as apposed to dish pistons

Yah, I forgot to mention it'll be running 1.6 rollers.
Also, I'm thinking compression will be around 10:1. Does that sound about right?

Re: Power with this setup?

Any other thoughts?

The compression ratio is really what I'm interested in. I don't want it to be too high, considering the flat-tops and 64cc chamber.

Also, I just bought the Comp XE 268 H cam. With the 1.6 rockers, I figure the lift around .508??

And what CFM should I run with this? I'll have to pick up a new carb since the Quad's not lookin so good.
