Hey there never posted in the orion thread before. I have a few questions for you guys. Whats your opinion on the Orion .21 abi 3 port(with the ceramics etc.) engine? I have a buddy who has one and im just curious here. What temps should these mills run around, also life longevity(speaking as putting at BDC and ARO after every race day and BDC after every heat/main). Last what plugs, i see the #5 is the plug that orion says to use but going from winter to summer in California is around 60's in winter to low 100's/90's in summer... Thanks for the help!
