    mine is a LUK brand....when I had the 350, advance bellhousing, and toyota stock 4-speed I ran a Centerforce.

    So long as it's a diaphram clutch and not a 3-finger jobbie, you should not have problems.

    the key is to find out what's hitting and where....and only some time/inspection work will find that.

    I put my pilot bushing in backwards the first time. Then, while bolting up the tranny, I gouged the bushing with the tranny input shaft and jammed some bronze bits onto the bearing surface. That caused the tranny to drag with the engine and it felt like the clutch wasn't disengaging.

    After fixing that I still had trouble with the clutch and finally solved it by pulling the slave cylinder and holding it right-side-up while bleeding to get the last traces of air out. Still, my clutch felt sticky for quite a few miles until it broke in some.

    Stock engine, bell housing, throwout bearing, throwout fork, and finger-style clutch from '69 C30. Works fine now.

    I emailed you a picture of 2 types of GM release forks. Just tossing ideas around. There may be a difference between them as far as leverage (travel distance).
