Yes. Cometic makes A nice rear main seal. I use them on all my engines.

Would you have a part number and do you think it is superior ...sorry to put you on the spot

I don't know Chris, but I've seen pics on here of some of the engines he's built. If he's using a Cometic RMS on all his engines, then I would bet they'll hold just about anything.

Check this one out - it's a pretty outstanding combination of Engine Art and Horsepower PORN!! http://turbobuick.com/forums/threads/job-well-done.383663/
