i know our stock compression ratio is 8.2:1 and i know everyones trying to ad more boost but wouldnt it also work to raise the piston compression a little say up to 8.5 just below the stock n/a's i mean i know that would raise a new set of issues for timing and predets but it would be about the same as adding a few more lbs of boost different power band aside has anyone done this or has anyone made new piston heads for our cars if so who what where when and how much gains did they see over stock. (i was digging through my chilton guid notised we were 8.2 and the n/a 3.8 are 8.7 kinda struck me that maybe we could gain some by increasing our compression)
