real main is leaking on my 360. Leaking bad enough that its leaving a small puddle and making my clutch chatter. What is your opinion on the best anti leak rear main seal out there.

Thanks
Ron

65 speptline with fresh 360 with leaky rear main

It is very rare for a leak in a small block--the crank seal area is nicked I bet--Not much else can cause a leak on a small block.
A big block..holy %$#@!! I went 24 years / never had one leak. FelPro started making seals offshore and Kaboom!!! I have used every trick in the book, invented a few new ones , and to this day I HATE doing a BB for that reason.
A small block can be fixed even if you use a China seal--If it was a big block....I would sell it.
