Andy, The most common mistake people (me included) is too much cam. Small blocks are more sensitive to large cams and carbs than big blocks. A 275 degree (advertised) cam is a pretty good all round cam. High lift won't affect idle like high duration will. I put a 272 degree, .510 lift cam in my 10 to1 460 Ferd and it runs strong and will idle at 500 rpm. My 451 stroker has a 275 degree duration and .525 lift. A single 4bbl in the 600-725 range on a dual plane manifold should do the job. 3.50 ish rear gear is good for cruising. You need RPM and light weight for a drag car. RPM = $$$ and less streetability. But what do I know??? I guessing it's a poly, therefore see Gary P. My brother's 70 Cuda 440 with 3.90 gears, crossram, 12.5 to one. and mega cam runs in the low 11's. He drives it to some shows, but gas is 4.00 a gallon, it runs hot on the freeway, and you can't hear yourself think in it. He trailers it to most tracks. My computer program shows my 451 car to run about a second slower in the quarter. But I'll be able to drive it all day and enjoy it.
