He said he is having a third party evaluate the design to see if any changes would in fact offer improvement. If any of you have suggestions or questions feel free to call him. He is a very nice guy and will love to hear what you guys have to say. David 865-310-7513

[/quote defbob... have you had any luck with the one piece rear main sealing... or have you not had the motor together yet? I seem to remember talking to a guy from HP products a number of years ago... he seemed to be a very nice fellow if I'm remembering correctly. At that time they had an aluminum one at the show and they were still working on the iron. I believe I was telling the guy what a real pain it was to get it right. Good to see that they are still after it and good luck to their company ]

About the rear cap, I didn't use o-ring material on the rear cap sides, I just used silicone in the passages. I did use a Mopar Performance rubber 2pc rear main seal. I did not get to see if the silicone was enough to seal the rear cap. BTW, the rear cap was the hardest to remove
