What is the average cost of a bore and a hone, 3 angle valve job, magnaflux, cleaning, as well as any other minor work that would need to be done to a 350? I have a 350 TBI sitting in my garage, trying to figure out what would be the best way to go about rebuilding it. Anyone out there have any advice? Was thinking of doing a 383 stroker, but now I'm leaning towards just a new cam and valve job to save money. What would be the difference in hp and torque?
