    From what ive read the 7.4L has weak internals & a sc may not be most reliable option. i have same engine & saving my nickels for a 502 to replace it.

    Upgrade your fuel system and oil cooler .Arp rod bolts , upgrade valves. We ran 5 psi for 3 seasons prior to removing blower to sell the boat easier.
    The new owner ran the boat over a pile of rocks first time out!

    You are on the right track. You also need to put in inconel exhaust valves.

    I did this in my old boat. ran a 174 B&M at 5lbs boost. made 560 hp on the dyno. With the small blower the boat idled like it was stock.

    Oh yea, i used my stock fuel system and stock oil cooler. Just be sure to get fuel press and boost gauges to keep an eye on things.

    To build a motor with a crank rods heads and blower is going to be 15k. I have a 540 that made 625@5750 for 6k. Only has 22hrs on it. This should rocket a 24 baja over 80.

    Sutphen30, are the blowers the polished 172's or the powdercoated black ones? I'm asking because I am looking for one to purchase asap. Port blower ate a piece of the flame arrestor.

    If your boat has a sail do you ride a horse to the ramp?
