I understand I did several things wrong on my first cam like using old lifters and not doing a proper break in and no oil additive.
Ok here is where I'm at right now. I ordered a new cam and lifters from the same place. I received the cam its a new one made in the USA the box says engine pro. The lifters are new old stock never been opened and still had the part number of GMC 839263. This was the only lifter they offer.
I looked at the previous post from 54 3600 and he had a picture with a NOS box that sold on ebay. According to that picture the that part number is Chilled Iron Tappets for forged steal camshafts.
I called the place I ordered it from and they said they only sell the cast cams and even there reground cams are cast not forged steal and they have never heard that the lifters are for forged steal cams. They said in all the years of selling parts no one has had any issues with there cams and lifters. Go Figure
I'd love to here from someone who has used cams from Chevys of the forties and see what issues if any they have had.
I'll post a picture of the lifters on photobucket and add a link on here.
