I have way too much invested to stop now, almost like the gambling addict that keeps going hoping he will finally win all the money he lost back LOL.. I feel Like I am very close.. This engine will be a bullet proof screamer. I will bring the Puma to Carlisle next year along with the GT4T, I will hold a raffle and the winner drives their choice of the two from Louisville to Carlisle, we can switch halfway so they can drive both. Any interest LOL ?
