What Pistons should i pick for my Eagle 383 Stroker Kit i am purchasing for my street car prodject? I will bw running So. Cal. 91 octane swill. My choises from eagle are as listed on there order sheet below. I will be using 62cc chamber Trick Flow Heads which will get me at apr. 11.4 to 1 which may be a little to much for the 91 octane. My other choice is to go with the KB dished pictons and mill the heads down to the compression i require.Anybody have any experience with this???.........Thanks Gman
