Thank you folks.Now for the update and our next hurdle.We had it running for about 45 minutes.It didnt stop smoking the more we raced the motor the more it smoked.We did another compression check its up to 75psi from 45psi.Thats still very low.Do you folks think its time for a ring job or do you think they might loosen up?This is the first time this truck has run in 35 years.
