Bore to 98"
Port t/body or replace with 51mm HPI
Heads that move 155-160 cfm @ 10"
Set compession to 9.8-10.0
That'll show those 103"s your tail light........

what are the advantages/disadvantages with porting stock throttle body vs. new 51mm hpi?
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
"listens to the flow bench & can tell what the heads are flowing", that's a good one
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.
yes I know mike,i was kidding too.his (and others) dual injector P/G bike is one of the reasons I left the gas classes and went to nitro.mike,jon miller and others running 7.30`s on gas was too much for my wallet!! yes they are VERY good

I figured on both counts; you knew Mike and were kidding. Mike sold his drag bike last year; says he is too old and fat to race any more but recently bought a 600cc Honda and takes it to a local track on track days; learning to road race now. 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.
