Okay what kind of oil should I use? Weight wise. I plan on installing a turbo kit once winter is over with since she will be in the garage anyways. I didn't want to pay for 2 different tunes lol. Hopefully I can break her in before snow comes.

 

use whatever your engine builder recommends.

 

Chances are any engine in a nascar has been broken in on the dyno, they have alot of tricks and specialized tools for engine building in nascar such as seasoned blocks that are left outside to oxide which removes the impurities and the type of crosshatching they use to seal the rings, plus specially coated rings and types of lubricants for short break in periods.

A really good engine builder doesn't let an engine go until it's been broken in first.
