Hello Chris Craft SBC Think Tank!
I have been faced w/ some interesting questions regarding my 327Q.
Fisrt has to do w/ compression ratio. Cylinders bored 30/1000ths over. I have new pistons, however the face is flat w/ 2 slight reliefs for the valves. The old pistons were "dished". I am told in order to lower compression ratio to maybe 8 to 1?
Question. Can I use my new flat top pistons w/o causing a problem. I know that compression ratio will be increased, but how much?
Has anyone replaced "dished pistons" w/ flat faced pistons?
Also, Intake valves have been changed to reflect 2.02.
Cam is Extreme Marine Comp Cam which is mild but somewhat hotter than original.
Any advice on the pistons w/ that setup?
