Ok, so I re-read the 307 (now 311 pages of post) and I feel quite confident in stating that I am almost 100 percent positive that a lot of what I've read has no actual bearing on actual bearings.
So, if I do boost the performance of my shameless, what type of HP gain should I expect to see?
Also, which type of thread is correct for a 76 550? I want to do this right the third or fourth time so as not to waste too much time.
