Yes, on my research wiseco was the better choice. Arias was my 2nd choice. The piston was made to how I wanted instead of how everyone else is running std wiseco's. Tomorrow me & brother "Dougie2" are pickin our blocks up from the machine shop. So ETA on the motors running, possibly 2 weeks... Also, The way we have always had best luck setting in the rings were to get the motor around 235deg. then letting them cool 100% down, after that, rings have always seemed to be seated in properly. Those motors are still running to this day. Also back to the piston issue. Anyone know if jE has fixed the problem with clearance issues. Alot of people have had good luck with jE Pistons when the clearances are set further apart than what jE says to machine block to. What jE says seems to be too tight causing internals to sieze up. If anyone has any other TIPS for a better break in period never hurts to have more than 1 or 2 tips. Thanks all
