Chavis Motorsports or Turner is where I would send mine if I was looking to. Miller is good but way too busy and wont answer the phone..Ive called 5 times before and let voicemails each time saying I wanted to purchase 3 new motors and never a call back so I guess hes happy with what customers he has already. I feel like maybe he would be too busy to give you the best he can always. KSR is good too. Theres tons of good ones and all very close and any can win any given day, I would call around and find who talks to you the best, gives you there time, and makes you feel comfortable with them. Some you will just not like at all, so start calling chavis, turner, xcaliber, miller, sbr, ksr, and id also call Tony power, he will give you his best and is a great person. He will talk with you whenever and really is a racers friend..631 433 3295
