Over bore pistons

Pishta I understand that there is a length difference. Im wanting to know if the 2.2 piston is compatible with the 225 rod. And if the compression will drop below the stock slant compression ratio. And if it will work would it be cheaper or close to replacement stock pistons?

lol the stock compression is 7-8:1... with the piston anywhere from .140 to .210 down in the hole... also cc's of the head ranging from 54-58...

so if you do the math as me an SS were doing a little bit ago a 2.2 on the longer 198 rods/54 cc head gives you around 10:1 comp...

using 225 rod you would be -.3xx in the hole... or NO compression... so the 225 rods will kill your comp...

you can buy pistons from summit, stock style up to .080 over bore... im using the .080's with total seal rings and spin my motor to 6 grand... running 14's... and they are 12 bucks a piece!

BUT you said your looking for boost safe pieces so i didn't bring them up...

hope this is the info you were looking for
