need slant 4 barrel help 170 225

Nope, the Cliffords won't work with a 170. The crank register got bigger in '68 and that is the only thing that is going to cause problems with your swap. Slant cranks were drilled for a pilot bushing almost to the very end of production. Everything from the 170 will bolt up to a 225 as long as they are the same year range. That would be '60-'67 and '68 up. I've seen adapter rings to mate small register to large but don't remember where right off. I'll chew on it though. Hope this helps.
