Grab a handful of phone numbers, start callin around to different builders and see what kinda answers you get. Find one you are comfortable with and go with um. I based my choice on the fact that my builder was one of the few that actually answered the phone when I called, and he came highly recommended. He also took the time to go over all the details of the build, bike setup etc......
He also gave me his cell number and had no problem answering the phone after hours and on the weekends.
I know Damian is getting out of building frames, but I know he's gonna do a little work here and there.
IMO..the best stock cylinder motor guys are Dan Hull @ A&S, Rob Earl @ RDZ and Rudy Kurtz @ Port Magic.
No one has the track record like they do...proven winners and record setters....
But as said, start calling down the list. What good is a motor if they're not there to help you out....or take your phone call.
Jim at Passion Racing does all my work and not a complaint yet that I can say about him or his work, he's been a major help. Rudy Kurtz at Port Magic Racing builds some of the fastest shee's i've seen (at least at our tracks)
don't be affraid to give kevin herr at herrjugsracing a call he does great work and prices and costumer service is top notch.he did me a 4mil drag ported stock cylinder 2 yrs ago and now a 421 cub and i am always right at the top of the classes i run even with the larger motors.great guy!
