OK, if I didn't give a hoot about the fact that most everyone on this board was suggesting a mild 350.....and I just had to have a 283, this is what I might do with it. Damn the cost, full speed ahead.......

Static compression ratio with 56cc heads, 6cc flat-tops, 5.8cc gaskets, 0cc piston deck height and 597.9 cc's in the cylinder will be 9.81:1. Dynamic compression ratio above 3500 rpm's will be 8.580:1 with the intake closing at 35 ABDC @0.050" tappet lift. Dynamic compression ratio between just above idle and 3500 rpm's will be roughly 8.81:1, factoring in a 10 point drop in duration and figuring that the intake valve will be closing closer to 30 degrees before the lifters pump up than the 35 degrees after the lifters pump up. Not trying to muddy up the water, just taking another route.
After reading DCR results from several board members lately, I think I have been leaving some on the table using 8.5 as a good figure off the KB calculator and that with the very tight 0.038" squish (piston pops out of the deck by 0.003" with a 0.041" gasket), this motor should run fine on pump gas. I have seen fellows running 8.9 on the KB calculator with no detonation on pump gas, but I have been reluctant up to this point to use a higher DCR than 8.5.
