Not Ranked
Have made the choices.
Just so all who have been following this thread know waht happened, I have just oredered the parts and made my piston choice.
I' decided to go with a set of JE pistons that will give me 10.27:1 with a .039 head gasket.
These are unfortunately very expensive pistons at around $760+ a set as they are made to order but they are the ones that will give me the ratio I wanted so I felt that it was worth the price of admission since the other options were not good ones.
My other choices were to either put me in the 11.1:1 or the 9.3:1 ratios, and neither of those were what were wanted. One was to high for my comfort (and had a very high dymanic compression with the 6.20" rod length and my cam) and the other one at 9.3:1 was just plain "wimpy" in my opinion. So... it seemed a no brainer to go with the JE #194951 17cc inverted dome and have the correct 10.3ish compression ratio for what I wanted from this motor.
Thanks to all for your valuable input!
