Thinking FLT...
Thanks!
But consider your long term goal. Are you looking for 600 or more rwhp and very low 10's or even 9's for ET's? If so the TH400 or 4L80E will probably save you a lot of money in the long run. Guys have gotten 4L60E's into the high 9's but they never last long. Even if it lasts a season you'd be buying a new transmission every single year.
Are you content with mid to high 10 ET's and 500ish rwhp? If so then I think a max built 4L60E can and have had far more success. You could use a window switch and set it up to not spray through the shift. That'll help extend the life of the transmission as well.
Good luck.
