Thanks for all the responses, does anyone have an opinion on best way to evaluate motor to see if it is worth putting the parts and time into repairing? if it is a cracked head (great possibility) it looks like the parts needed:
heads
gasket set
head bolts
intake bolts?
oil pump? I've heard as LS motors wear, oil pressure becomes an issue
fluids
The Chassis is a really clean truck, unfortunately I do not know any specifics on how many miles are on the drivetrain. Might be better off finding a donor vehicle with less/known mileage that the chemicals our DPW dumps on our roadways here in Western NY tend to make not road worthy before the drivetrain is shot.
