Awhile back I had to change the oil pan seal on my 355 SB. Sitting at the bottom of my 7 quart pan was what appeared to be a brass colored washer. It was about the circumferance of the HEI distributor shaft and I figured that has to be where it came from. Low and behold, I put another 7,000 miles on the motor with that same dist. with no real probs. Now I want to change out my points dist. on the 402 with the HEI off the 355SB, but I'm wondering if thats a smart call concidering there might be a missing part to the puzzel. Also, I heard shoddy distributors can cause valve train failure and oil pressure problems. Any help whats-so-ever on this topic is greatly appreciated!
