Mail Order Parts
RPM Machine was the purveyor of my parts. They were nice and seemed knowedgeable, I ordered a 383 forged rotating assembly with H-beam rods they sent a 383 cast crank with I-beam rods and -20.4 dished pistons. They replaced the crank and rods and pistons with no rings. I had the assemble balanced but now I am going to have to get it balanced again because the parts are all changed. I am going to just buy the rings I need so I can put the motor together. I am not knocking the company but it has not gone very smooth for me.
