Is there a thread anywhere on here or does an experienced mech. know exactly how to break in a new sleeved block? As far as how, what oil (synthetic or reg. viscocity) and when to tune. How long to let run before oil change when first start. Things like that are important to know before I mess up an expensive block. Thanks a million for any help. Sorry for long ?

 

treat it like a new motor break, no syn to break it in.

 

break in slowly like u got a fresh new pair of air forces!!!! oil depends on internals.. if u have after market pistons and rods check with the manufacturer and they will let u know what not to use with there product

 

thanks guys.

 

anytime!!!
