RE: Engine Build Up
mark, i would bet that the stock pistons are still "flat", they are probably dished.
lear, im unsure of your explanation of the cam...292 degree...do you mean 292 duration? duration is measured in degrees of crank rotation, so i assume that is what you mean, but maybe im off base and im just not familiar with the term?
in the mirada, im running the mopar 528/284, with a 3500 stall and 4.56s...shifting around 6700rpm, trapping right around the shift point. the power range for that cam is like 3300-6800, i believe.
keep in mind though, with the big block, you start off with a substantial torque advantage over most small blocks...so for you go to to an intake that likes the top end, you lose less torque by percentage than would i with my little 340...i HATED the dual plane (mopar M1) on the mirada, and quickly changed to the edelbrock air gap, and i love that intake. the edelbrock ld340 is suposed to rival the air gap for the small block mopars, and i had one laying around, so the demon has the ld340 over a 509/294 cam, 2800 stall, and 3.91 gears.
