Any info would help I havent done this for 16 years or so. Trying to remember is tough with out getting out a lot of info and go through it. Have puut togeathe most of the parts I need to do turbos on my boat. Small blocks boost can range from 4 to 15 lbs or so. Planning on no more than 6 lbs to start out. Should put me in the torq range of a well built possibly short lived N/A BBC.
