2.7 stroker using 2.5 rods. Need piston info.
I have ran a couple ideas across some members here and i appreciate your replies.
I won't to do the 2.7 conversion but with the 2.5 longer rod. From what i have researched the 2.5 rod on a 2.7 crank spins faster then the 2.7 crank/rod.
I know the other possible alternatives - 2.7 (eta)crank/rod/piston/ i head. or - 2.7 (eta)crank/rod, seta/custom pistons. I have read all there is to read on these two (twice). I can't find the seta pistons and customs with this setup are difficult to get pricing for. Had difficulties trying to get correct specs to order pistons.
Regardless, I like the more tourqe to come from the 2.7 crank and the faster rotation from the 2.5 rods. A few have brought this configuration up, but i have not noticed much detail on the subject from those that have actually gotten this done.
1) I have only seen the reference to .080 shave off and relief recut once.
a) To get a 9:0 CR, what is the shave amount?
b) Is there a certain amount of shave verses CR amount?
c) will any machine shop know how to do this?
d) is there something special in addition to this we should know.
2) Details/specs of custom pistons with CR.
Anymore information would be appreciated.
