Cam for LA...
I’m all for the roller cam. Keeping the OEM rollers (if ya got them) has only their weight as a draw back. Heavy suckers they are. Cheap as heck if you need to get one or a whole engine set.
A lot of people suggest a retro d. I’m not sure who charges what on a regrind, but I don’t call it a huge win when you add in shipping to and from the regrinders. I’m sure you’ll save a few bucks.
