It's been a while since I've been here, a very long time. But I have a few questions for anyone that would be familiar with the 20B. I'm rebuilding an 88 FC with a 20b, I was curious I'm interested in using something like a TCI Competition Transmission or a Powerglide. Maybe something like a TH-350 or a TH-400, and then I wanted to switch out the rear and maybe bolt up a 9" or 10" Ford rear. Should I go with something different that would provide a nice even powerband? I'm looking for numbers between 700 to 900 hp which is attainable with the 3 rotor.

I'm also interested in going to a 5 lug set up with a bolt pattern of 5 x 4 1/2 or
5 x 4 3/4. What's the bolt pattern for the turbo II FC's or the bolt pattern of the FD? I'm trying to make this car my own with some assistance from friends and family. Also getting help from people on this forum would be greatly appreaciated. Thanks in advance for any help provided.

the fc/fd bolt pattern is 5x114.3, you will probably have more luck in the 20b section of the forum for your other questions.

 

I put the drivetrain from an '87 T-II behind my 20B. I don't do dragracing, so I don't stress it all that much. No problems so far.

 

Oh sweet, thanks for the info. Maybe I'll work with that then, what type of numbers are you putting to the rear wheels?

 

368 rwhp and 425 lb/ft of torque. That was before the rebuild. After break-in, we'll see if there's a significant difference.
