No experience with that one but I have heard one piece seals have been working well for Cleveland engines when the block is machined. -THIS- seal however does not need machining. It uses the same seal groove as the original. I like that idea better than machining the rear of the block. I would use that seal if I were in the middle of a 351C build without hesitation.

Dear Asa, It does not need machining. It is a direct replacement. I am in the middle of a 351C rebuild and I hesitate in gain some confirmation from any actual users. It looks more robust than the typical two-piece RMS. Thanks.

seal
No experience with that one but I have heard one piece seals have
been working well for Cleveland engines when the block is machined.
-THIS- seal however does not need machining. It uses the same seal
groove as the original. I like that idea better than machining the rear of the block.
I would use that seal if I were in the middle of a 351C build without
hesitation

Dear Forum,
TMeyer offers a one-piece rear main seal. He is very reputable and it looks good. Endorsed (?) by Kaase, too.

Dear Asa,
It does not need machining. It is a direct replacement. I am in the middle of a 351C rebuild and I hesitate in gain some confirmation from any actual users. It looks more robust than the typical two-piece RMS.
