I have a MK4 with a 302 that I want to pull and do a big horsepower rebuild next year. In the mean time I have a stout 390 I want to install but have a few questions/concerns. Will a C4 w/FE trans adapter hold up to over 400 ft lbs of torque? I'm told the T5 will not. Any A-frame or trans mount mods? I plan to do the swap with the body on. Any suggestions? Should I drop it in as a unit?
Any help/advice will be appreciated. Thanks, Racecartom
