I had a PTC and Kenny was Good to deal with but it took 4 conv from him to finally get 1 to hold together and get it right for the car. 1st one broke sent back, 2nd time broke it again sent back and asked for a different one set up for no nos as I was tired of breaking them. Got the 3rd one and he forgot to take the nos off the tech sheet and the shop guys built it for nos, it was a turd on motor. Called him again and he was willing to get me whatever I wanted so John Cope told him what I needed and the 4th conv was a Good one but the stall was a little high but I left it along. I was tired of rebuilding and also taking the trans out, 4 times in 1 year, but it is still working to this day 5 years later.
I will try a Lenny conv as my next buy for my other car.
