Moving to TH400...a few questions
I dont think you would come out cheaper and you will find that with the 40 you will launch slower due to the higher 1st gear ratio and besides 4th you will loose lockup on top of that and the car will be much more expensive to operate further increasing cost.
I would consider and built 60e either from us or any sponsor on this board can suit your needs and a stall converter dumdumdum
