This seems to be a great new product. Everybody I've read about who tried one, says it is easy to install and doesn't leak.

Butler has done some testing and seems to think highly of 'em. I'm not trying to promote any one or more businesses, person or people--just this one product, which is the BOP one piece seal. I'm sure these will be sold by other businesses.

But hey, for anybody who don't like anything but rope seals, just use the Best Gasket ropes and be happy.

Back in the '70's and '80's I bought neoprene seals for my 455 bracket motors from H-O Racing Specialties. I think they were actually made for 500 Caddy engines. I've read that the neoprene is actually tuffer than Viton--opinions differ. Anyhow, they worked great. Never had a problem with any of 'em.

For all Viton seals, it is suggested that the serrations on the crank be polished down, IF they are aggressive, but no more than .006. Here's some links with more info.

A fwiw, the dick head at Tin Indian Performance gets his rear main seals from the other dick heads at KRE. They are fakes... NOT made from real Viton material.

I personally prefer NOT to badmouth any of the big name Pontiac guys. They all know more about Pontiacs than me. I don't like some of their high prices. But I appreciate many of the products they bring to market, and the performance they have achieved on the tracks, dyno, and flow bench.

Back in the old days, there were no alum heads for Pontiac. No aftermarket blocks. No cheap stroker cranks. No cheap forged rods. Well, you get the picture. It's easy to make big power with a Pontiac motor now, thanks to all these aftermarket parts. Or you can still go with a factory block and heads. I think all this is good for all Pontiac fans.

If one lies, steals or offers crappy tech service from you it could factor into your opinion !
