heres my problem, i just got it rebuilt with wisco pro-lites, i added an advanced timing plate (at +4), a pro design cool head 21cc domes, and i have a low end port.
i have 320's in it now
the problem is that when i give her gas on the road, it will fly until about 1/2 throttle then just die (like it backs off or somthing)
it doesn't backfire, and it sounds crisp and clean
i used to be able to beat a my 400ex but not it barely keeps even with it
any ideas
