Quote: This thread is jogging a bit of remembered tech from back in the 70's. When and only when, running a roller cam some guys would bush the Mopar lifter bore .904 to chevy .842 so they could use a lighter and cheaper chevy roller lifter. The wider base circle of the mopar didn't really make much difeerence with a roller lifter. Anybody else remember this?
I would be interested to see if anyone on here has done this. When I asked my machine shop about this they said why would you do this when chev guys take theirs out to .904 size. I have not found a chev guy yet running anything but .842.
