I have been giving a set of original, big block valve covers. Chrome but I will scuff them and paint them. They look correct for a 1969 but I am looking for opinions.

Hi guys, I've been thinking about upgrading my rearend from a non-posi 2.56 to a posi 3.08. I came across this fella selling this slightly used Eaton Posi. Is this a good price ? He suggested they're about 900 new. Regards, Scott (LandShark ...)

As the subject heading asks. Does anyone have info on how many 396 and 427 cars were built? I can find that 10 2+2 convertibles came with a 427 but what about other applications. The VVS I got for my 69 396 2+2 only indicated that 1943 2+2 coupes were made but no power train break down.

The original fan blade is now 3 1/2 Inches from...

I am cleaning stuff in my tumbler and when I was putting this one in the tumbler today I noticed it doesn't have a seal in it. I never realized not all of these were the same design.

looked at a number of sites and see all kinds of different answers. 60 over I think all would say ok but what about 70, 80 or 100? what do you think about sleeving back to standard? This also has to do with saving an original 66-69 427 block
