price is a lot cheaper with porting your T.body,but runner size can be made bigger with a HPI unit.when we bore HD t. bodies,we open the stock runners to 1.700,but that's as big as you can go on a stocker.on a HPI,you can go up to 1.800

That was a bit "tongue in cheek" but seriously, the guy is very good. Do you know the Lozano brothers? If not, next time you are in front of a computer and have a few minutes, check them out.

The new owner of his drag bike blew something apart in Houston a couple of weeks back so it's back in Mike's shop. Also sold his 130HP Dyna and now rides a K1600 BMW. Good people, the Lozano brothers; Mike has helped me out a lot and I have learned a lot from him; I just need to get him talking on my level.
