Does it require a motor pull? Yup. Amongst any number of other changes. It is without a doubt a different kind of power that with the TT bottom end. It was continuously quicker in the 1/4 than other TT's with upgrades. Not to mention the turbo Supra. There's room to improve it and I will. I think the price will be lower than what most expect, so maybe it will be practical. If so or if not, we've learned. Thanks for your interest.
