To much cam??

Try what moper was talking about up there and do a cranking pressure test to see where you're at. If it's just a matter of retarded cam timing, you can probably do just like they're talking about and swing the cam advanced 6-8* and have a much more fun vehicle to drive.

Personally I'd recommend going with a little more gear...like 355 or 373 at least. I guess it depends quite a bit on your intended usage. If you want to drive this thing 20 miles every day, a cam change may be on your horizon. If it's just a weekend toy, bump the cam up, get some lower gears (and maybe some more stall), tune the dizzy, and go from there.
