For dragging, I would go with a top end port, CPI's, drag key (or better...ignition box), V-force reeds, and shave the head .030 too run on pump gas. For more octane.....I would then go with another head.

 

got all that but port and polish

 

Porting, alky and NOS then.

 

Tony Doukas all the way, they have 585 power valves.

 

patriot racing DOES have a website, but dan is hellaciously backed up. Heck he doesnt even answer the phones half the time because he has his head in a motor.

Trinity is a joke. Ive seen numerious 540cc cheetahs dyno at 115 horses...far lower then their "claimed" output.

Rudy kurtz is one of the best with small bore motors, as well as A&S. Id personally go with rudy as he is a much more relaxed down to earth guy

 

give me websites here

 

i gave you a #

 

Don't forget about K & T performance out of UT they can build some super fast stock bore bikes. They are the ones that build crankinstien also. they have a website it is K&T Performance

 

Here is a link for patriot racing, I was thinking K&T also. I have talked with Dan at patriot racing quite a bit and he is a very straight forward good guy. I would not hesitate to send him my stuff. I am sure K&T is just as good, but very hard to get ahold of, at least for me. I have not been trying for a while, but when I was I could never get anyone. Later I heard that they may have been out of town for something, so take that for what it is worth.

If you want to talk to dan, email seems to be the best form of communication for him.

There is a stock bore K&T motor that runs a 4.4 at the Texas Sand drags.
