About to build my coyote 5.0 short block for NA only on E85.

the best piston I can find for NA is the Mahle 12.5:1 that's w a 0.040" gasket.

it weighs 395 grams. Stock pistons are 372 grams.

looking for ideas on super lightweight w short NASCAR type ring lands and minimal skirts, short pins, etc..

thoughts appreciated.

Bump. I need some help ya'll! Here is what I have it narrowed down to.

Mahle 12.5:1 piston if I can find it in standard bore 92.2mm.


Diamond 15:1 setup (reduced dome for 13.5:1 on E85).


Wiseco 12.5:1


JPC CP (11:1 shown).


There are also very high quality Manley 12.5:1 slugs, JE, etc..

Goal, make more power than the average Coyote.

You might have to have them made, PM Mark From Probe on here, I'll look at my new CP Piston book and let you know.
