A good read....my 505 has a few parts to finish collecting and its ready to go. I have a .541 lift roller cam from Comp plus roller lifters, a HV Melling Oil pump, the Bronze dist. gear. (But I have to change out that bushing), I have to get that fuel pump rod as well as all the pushrods, I have the cam button. I just spent the little money I saved and bought the Harland Sharpe rocker assembly. Matched with the Eddy RPM heads and swapping out the valve springs for the COMP recommended ones...I am hoping to own the beast she was destined to be. Hopefully getting to the goal of 550 realistic HP.
