I bought a used shortblock that was in good condition. I installed my ported and milled head plus all the boltons but I left stock fueling for a couple of days. I ran lean until I upped the fuel press with a reg someone lent me, now smoke is coming out of my exhaust, could running lean (I heard no detonation) be the cause of this? Will I need new oversize pistons or willa re-ring suffice???

thanks

 

well first it could be fuel u seeing

but u need to tell us what color is the smoke to determain what it could be

hopefully ain't rings unless u like to spend 400 plus just on labor

ouch I have done three times in the past year

yeah I know it hurts to bent over still

LoL

 

the shortblock costed me 300$ from the importer but I guess Ill have to buy new rings and even maybe pistons (ill get them oversize if I have to get new ones)
