    That's the only part I haven't figured out. Static display with crate popped, or rip it , then display it

    Tell me more about this tuned pipe if that engine will bolt up in place of my 428.

    Took the engine out and cleaned her up. Sanded down the casting marks in the intake and head pipe. found the issue why she is not pumping fuel. Someone broke off the carb fitting and tried to glue it back in.. If anyone has a chean bn38 or has an idea on what jetting to use on a 38sbn let me know.









    Someones homemade sparkplug wire..

    I don't know that I have seen that Sport model before. What year is it? Was it made by Wet Jet or Mastercraft?

    Cody, I'm pretty sure a SBN will fit on your manifold. Huge upgrade over any BN on any motor.

    My set up is a 1994 Brute motor. OEM it came with Low jet 65, high jet 150, black spring and 1.5 seat for ~38 PSI pop-off. Since I removed the OEM flame arrestor and installed a Westcoast Velocity stack, that pop-off would be way too high. I took a guess with a dull spring and 2.3 seat, ~20 PSI. This was my initial set up.

    First day tuning at the lake I found the pop-off still too high as it hesitated and stall when you hit WOT from a stand still. So I opened up the low jet to 77.5 and dropped pop-off to 19PSI with 2.5 seat and gold spring. It works perfect now.

    I have the 1994 engine with the westcoast looking pipe and the 1994 aluminum water box. I never tried that plastic water box that you have. There is a different exhaust manifold for the 1994 "tuned" pipe on the brute engines and there would be for the motor you have but I doubt it was ever made. I do have a tuned pipe that will replace the breadbox pipe you have. It came with my WetJet but never got installed. PM if interested.
