...460 Ford Rear Main Seal In A 455 Buick Motor...

...I had breakfast with a friend the other day who has built plenty of race motors,...and he told me the that a non rope rear main seal from a 460 Ford motor works in a 455 Olds... ...He suggested that the same may hold true for a 455 Buick???... ...Has anyone ever heard of this???,...or tried this???...

 

It is discussed on the Board in the past posts but there is a new design for the seal out that is even better per JW.

Here is the information you need about the BOP seal that is better than the 500 Caddy and the Ford 460.

i think the 460 seal fits the olds 455 and buick 350

 

Get the BOP seal Finally no leaks

 

The Ford 460 seal fits the Buick 350. I have used it in several engines.

National #5116 fits the Buick big block. I've used this one in several engines.

 

...Thanks a ton guys,...looks like a bearing inspection and a BOP...

 

Any certain year on the 460 for the 350 and the national 5116 for the 455 is that a part number for all brands?

Any year on the Ford 460 should work as long as it's the neoprene seal. The one I have used is the Fel-Pro seal.

 

Does it work also for the 430? Do you have a part number? Old link doesn't work anymore
