He hung up on me when I wanted my 904 rebuilt to take the 416 power (maybe 550 HP) and retain the kickdown. I knew it would work cause I was already running it.
Kenny at PTC got a kick out of that and did my 904.
Hard to imagine John hanging up on anyone. I've been dealing with him for years, one of the nicest mopar guys around. Willing to help, even If you aren't buying anything from him.
