I'll have to re-think this. I've been trying to utilize what I already have on hand without buying more stuff, like hydro lifters. Perhaps what I want isn't doable with what I have.
My other option would be to simply plop in another 288R Comp cam. The engine was happy with it before. I would just have to alter some other plans I had.
Altering plans is something I've been doing a lot of lately...
