I don't really post at all, but I have run a 400 transmission in my 68 charger for a couple of years.
I recently removed it only because the car went to fast for the 5 point bar in the car.
It really is not that big of a deal to make fit. If your car is tied by frame connectors like mine is,
we cut the transmission crossmember to the center of the mounting bolts on each side. Then drilled out the
spot welds and made our own crossmember from rectangular tubing. It will put he transmission down about 3 degrees
lower than stock, but I was able to correct it with wedges under the axle. We never cut the factory tunnel.
It really is a sweet setup. I never experienced any vibration on the street or at the track. It easily stood up to a 498 wedge with
440-1 heads, 12.3 compression and a big shot plate system. With a 3800 Continental converter and manual valve body it really
was a great combo. Leaving on the transbrake with the unit the 1st time scared me straight. It also got me kicked off of all the
local tracks I can go to.
I returned the car back to the original 4 speed because I'm sill
a mopar [censored] at heart. And because racing a full size b body takes a lot more money than I'm willing to spend on a car I'd rather
drive

BTW, I still have the complete setup soup to nuts including the driveshaft and oil cooler if you do not have one already sourced.
