Re-grinding a cam, educate me please

if it were me, i'd send my old core in and have it reground by them and save a bit of money, and if you have lifters i'd do the same with them.

you're not wildly changing anything specs wise so it'll be no problem for them to regrind. besides, what are you going to do with those old cores? make a lamp of of 'em?

if you need new lifters, there's a lot of choices besides comp. i've been using melling for quite some time and been happy with them.
