For the application I am using it for, strength is no issue. Plus, I can always change it down the road (not literally ) For now, if it bolts up to a standard chevy bellhousing and regular clutch stuff fits, it will be ok.

My concern also was that since he advertised it as '64-'67 Nova, to me that spells 4 cylinder stuff, and I was afraid it would have some goofy bolt pattern or something.

I know Ford changed their balance from 28 oz to 50 oz in like 1981. Are there similar changes in Chevies, like some were internal up to a certain year then went to external?? Mine is a 1999 5.7 Marine roller cam engine. Does that sound like 168 tooth or 153, or what?


Thanks for all the help, guys.
