Hi all. I'm new to the forums, just registered, first post.
I am resto-modding a '69 fastback and it's time to choose a motor. I already have a T-56 transmission and I am eyeballing a 427 for the motor. I was wondering if anyone has done this. Any known issues with this?
I don't foresee any problems. They put T56's behind 500hp 5.4's (GT500), GM LS motors, and Viper V10's. As long as it's built to suit the power requirements, it should be fine.
The only issue is going to be mating it to an FE (or smallblock) bolt pattern. Give Bruce at Modern Driveline a call. I'm sure he'll sort you out in no time
All you need is the T56 and correct bellhousing. Modern Driveline has them both. Slapping a TREMEC TKO or T56 behind a SBF is simple and done all the time.
