So to sum things up. I got a personal observation. My very first HT did 46 mph one day as a stock engine, NT carby with very mild porting at high elevation. The jug wore out and I never could blow that motor up. It took it forever to get to that speed. Guess I could call that a real hot rod lol? This of course means I still have it. I wanna say Map I can't help but feel like you detuned your H.T. That is a whole lot of modifications for such a ''small return'' IME?
The next H.T. motor I will not be playing around. Now that is real a pun.
Seriously I read about all this stuff constantly..
I see no reason a motor with good bearings cannot take it? Only reason a lot of my friends and acquaintances blew their motors up was because they did not head my recommendations. You already found bearings your self. Thanks for those links by the way.
What did you think of your motion industry bearing?
