My head is spinning. I need some help building my transmission. Ultimately, I would like to Whipple my 2012 2wd. My transmission builder is telling me not to, that I am asking for trouble. I am building the engine to make 600hp N/A. Should I stop there and be happy. So, I do some research and find that I can purchase adapters to put a 4L80E in the truck. Has anyone successfully done this? Do I have other options????
