New engine ?s
I just got my Low Cr 408 with patriot heads done and am trying to break it in before we throw it on the dyno. When I slow down and come to a stop it starts throwing a decent amount of smoke through the exhaust. When I start driving again most of it goes away. Is this just because the rings arent seated yet? All I was told was no boost while I am breaking it in. Anything else I should no? How many miles before I can put 14psi through it on the dyno for tuning?
