Hey guys,

Just curious how with everything else being the same how much more power my engine could pick up with a compression bump from just under 9:1 up to about 10.5:1? The current configuration has the pistons below the deck about .083". So with the new compression I would be zero decked with about .040" quench. Here is a mild run down of the engine...best time is in my sig...guessing at about 320hp at the wheels

1991 360 Roller block
Bone stock bottom end
9:1 compression
RHS heads prepped by Brian at IMM engines
custom ground hydraulic roller from Brian at IMM with specs as follows:

Gross Valve lift with 1.6 rocker arms- 577 int., 569 exh.
Duration at .050”- 230/230
Lobe Separation- 106
Cam installed at 101 Intake Centerline (5 degrees of advance ground into cam)

Topped off with an Eddy air gap, Holley 750HP, 1-5/8's headers, 3" exhaust

So how much more power can I expect to make? If i can get this engine to e/t the car to a high 11 on the motor I would be super happy.
