zoom flywheel questions

Any standard 10.5" clutch should fit no problem as long as it's the right spline count for the input shaft on the trans. I wouldn't worry too much about it bolting up to the flywheel. Bolt holes lined up just fine on mine, I'm using a McLeod 10.5" 23 spline clutch and pressure plate kit rated for 350hp. 375hp is probably on the high end of what you'd want to run with this flywheel. It is a stock replacement after all. But then again I'm getting ready to build a 340 and I intend on reusing the Zoom flywheel, if it explodes i'll let you know. I think it'd still work with your engine, but if you want peace of mind then the 440Source flywheel is only $100 more.
