Kudo's to you Steve for bringing this up and letting people know.
I am most always very complimentary regards vendors.
In the case of Muscle Motors( and I live very close to them) I can honestly state from buddies and local racers who have used them, most all either know better or won't again.
I have used two shops( both further, and much further) away.... Best Machine and Hensley racing, with great results and service after the sale.
I intentionally avoided using Muscle Motors.
