I already have the blower, although it does need a front bearing. I also have the Apache heads, A Molner 3.888 crank, and some H beam rods out of a Dragpak motor, and an older 5.7 motor to work with.
I see the Helcat uses a double belt system, and maybe an eight rib belt for the blower? Since I don't plan on AC or power steering, I have some options like a custom belt route for two belts, and spacers.
