I currently have a 350 sbc 60 over with forged flat top pistons and stock crank and rods. It has stock 76cc heads. Edelbrock RPM performer intake and hei distributor and MSD box. All I remember about cam is that it is 488 lift. I lost cam card as I built engine 10 years ago and moved twice. On a chasis dyno the car made 267 hp and 307 torque and ran out os steam around 5500.

I would like to do a head and cam swap and get the motor to around 425 hp. The heads I am considering are the aluminum Patriot performance 185 cc with 64 cc combustion chambers. The heads made 420 hp in the Sept 2012 Carcraft magazine. They did not specify the camshaft thet used. What will my compression be with flat the 64 cc heads? I am open to other heads but my budget is $1000. I would like a nice choppy idle.

The car this will be in is a 1968 camaro with a 12 bolt rear with 3:73 gears. Tremec tko 600 transmission with .64 overdrive. Car is set up to handle, not drag race.

I will be going the 1/4 track in late september with some buddies. The cars they have are a LS1 Trans am, 2007 Shelby, and 2012 Challenger srt8. I would like to step up my game and show what the old school engines can do. Any help would be appreciated. Thanks
