When we were running ours for racing, we used (hold on to your hats boys and girls) an old Erson grind..... Yup, 472 lift with a 309 duration w/ 9.5-1 flat tops. We did the 440 30 over also with a torquer intake, 750 DP and Hedman headers with stock electronic ignition and a chrome box. With 4.11's, it would pull all the way through the quarter in the low 12's.

If you have 8:1 CR then your choices are really limited. I'm running the MoPar .455" / 272 in my 10:1 440 and you saw the results at Sac Raceway recently. If your pistons are down in the hole about .100" then you really should pop a set of 915's with a steel shim gasket to get nearly another point of compression. Otherwise you are bound to the Edelbrock perf cam (or equivalent) designed for low CR engines. I'd say 3.55 gears will be a great choice for that motor.

I running the comp xe 274 in my 440 with edebrock rpm intake, headers, 2400 stall and 3.23 gears. I am very impressed how hard it pulls from bottom end all the way to 6000. Loads of bottom end torq and has a good sound at idle.

What gears?
Why limit yourself to Comp cams? They are Chevy guys!!! What about Engle, hughes, lunati?
My suggestion depending on gear.
Hughes 2332 (1st choice, hot street cam)
Lunati 60302 OR 60303

If you are stuck on Comp.
274 or 275xe

With your bigger cam and headers, I would recommend installing 4* adv to get some low end.

Pretty nice combo btw.....Im guessing at least 3.91's out back?

You might even consider calling and talking to Don at FBO (4secondsflat.com), he runs a speed shop for MOPARS and is hooked up with Racer Brown, he custom ground my camshaft. He'll grind it to match what you have and what you want.

If your compression is so low I would look at a blower ( Paxton or Procharger). Get an appropriate cam.
