I put 64cc dart iron eagle heads on a 350 goodwrench engine (12cc pistons) and made 9.3:1 cr, used a compcam 260H (212/212), and it runs on 87 octane with 38 total degrees of timing, 2000 stall, 2.87 gear, and 3000 pounds.

Would you like to know how to change things to make that 287 duration .480" lift cam actually work the way you wanted it to?

Increase the compression ratio (swap on a cylinder head with a much smaller combustion chamber 58 to 64cc) {while a vortec head works very very ,very well and is highly recomended, a low cost low buck very effective alternative is to use a home ported big(er) valved, home modified 305 HO/TPI head or a 350 TPI head.} anything with a 58-64cc chamber volume other than the swirlport heads will work well.

Install the cam slightly more advanced in the motor (3 to 5 deg more advanced)
Recurve the ignition distributor for increased idle timing yet the same max spark timing. (you want 22-24deg at idle and 34-36deg at max advance)
Limit the mechanical advance travel limit from 20-24deg stock to around 10-12deg.

Install a high stall torque converter (2800 stall minimum, 3500 stall best)

install higher rear gear ratio (4.10 minimum 4.56 best)
get long tube headers.
get a dual plane hi rise manifold and 750cfm carb.

Make these changes and you'll get what you were and are looking for.

Well I bought a comp cams 260H last night. 260 int./260 exh duration. .440/.440 lift. I think this will be the best bet for what we want. And later on we can do a head swap to bump up the compression a little bit.

I'm running a 78 Camaro XE 256H 3.23 and it drives fine, sounds good at 800 idle. Not sure how heavy your car is (mines 3600) but i think you would be safe to run a 262H if you changed your gears.
