360 cam question

OP, I hope you (or your brother) have done your homework on this swap. A 360 and early A exhaust manifolds can have some pretty significant fitment issues, depending on the year of the 360; or more importantly, the year of the heads you're using... as well as multiple other issues if you're swapping from a slant 6- there's more differences than you may realize. Start using the search feature in the "Early A Body" section.
