New build A833 18 spline with Gear Vendors OD.

You’re going to love that aluminum flywheel. I’m running the aluminum Ram 2503 flywheel with a 900 Powergrip. The clutch engagement is a lot more touchy than my old Hays B/B but I’m getting used to it. I think we’re running similar engine combinations and I can tell you that the stroked W2 with aluminum flywheel will rev like a sewing machine. You’ll hit 7K rpm before you can blink. Lots of fun!
My 360 based W2 engine hit 8k in a blink with factory flywheel .
My new 408 W2 with only 246/250 duration not so fast even with a 20lb McCloud SFI steel flywheel .
