I have a 421 bellhousing and cant remember if I can use the big flywheel and 11 inch clutch with it . Will it work or will I have to use my blowproof lakewood or a 621 ?

Oh, good ! Thanks Ken. I was thinking I could only use the 10.5 with that one.

Pretty sure that the 421 housing is 1963 and the hole is a smaller diameter for the front retainer. Tom.

That's alright Ken, I made a mistake too. my bellhousing is a "403".... I dcn't know why I had 421 in my head. I am pretty sure the 403 is also for a 10.5 clutch too though....

403 is a 10.5 clutch housing

621 is an 11 inch housing.

I agree ken... I am getting everything ready so when I start the swap I can get it done quickly and keep driving... I just need a couple more things and a couple days off work....
