Engine rebuild in Montana

If you are gonna rebuild a teener,for a truck;
IMO, it behooves you to bring the compression up, and put a lil more cam into it.Even if for no other reasons than for the Part-Throttle torque increase , and boost in fuel mileage. Pistons cost about the same, the cams all cost about the same.
If you intend to keep the log manifolds(edit; AND the stock cam) then there is no point in going very far, nor a good reason for a 4bbl.
The stock cam is in there for a reason and it was never intended to be very good at anything but having a smooth idle,lol.

Oh yeah; welcome!
