Doug, what cross member do you use with your 200R4? We modified my G-Force 200R4 cross member and made it work for the T56.

Here's what we did to modify my existing G-Force to work with the T56. I was the designer while John (Jynxd1) was the lead engineer and machinist. Thanks John...



The T56 transmission mount needed to be about 1 1/4" lower and and inch or so towards the front than the 200R4 mount was, so we cut a C-notch out of the front of the g-Force cross member.



Then tack welded plates to box the C-notch in and tacked a new mounting plate at the right height inside the notched part.





Then took it to the car and test fit to make sure everything was correct before final welding.







We got the height perfect. I removed the rubber bumper on the top of the T56 and the tail shaft height is now in just about the exact same height as the 200R4 was and I can fit a straight blade screw driver between the rear two cover bolt heads and the floor pan.

John finished welding it up and I painted it up and it'll be ready to go back in tonight.

I know!!!! I'm going to try my best to get it all done in time.

Do you have your T56 behind a SBC?

SBC/T56 crowd here! To this date I think the T56 was the best thing I ever did to my car from a fun-factor stand point.

Looks like that flywheel is externally balanced. I don't know offhand whether your engine is balanced internally or not, but that flywheel may need to be rebalanced to suit.

I would guess that is a stock 1-pc rear main flywheel. As long as the block is a 1-pc it should be ok. My block is a 2-pc and I had to get a conversion flywheel for the LT1-style clutch.

BTW....tonight is the moment of truth. We are taking the T56 apart to see if the internals are any good..........wish me luck!!

Looks really good! Im probab;y going to just buy a new GForce T56 crossmemeber bc I want to sell my 200r4 set up as a complete kit.

Do you have any pics of your tunnel mods to make it fit? And shifter?

I've heard the G-Force cross member doesn't get the tail shaft nearly as high as we did with the mods to mine, be prepared for that. I didn't take any pics of the tunnel that I recall.

I just lifted the trans up into place minus the shifter, marked the four corners of the shifter housing on the bottom of the tunnel, lowered the trans out of the way and cut out between the holes. I had to walk around the car a few times first before firing off the cut off saw..."should I do it..should I do it..." then I went after it, no looking back now. ;)

Once you get the shifter housing going up into the floor, you'll see where the tunnel needs massaged on the driver's side...where the lock out solenoid hits the floor. An area maybe 3" long by 1.5" wide needs moved out about a half inch or so. Five minutes with a hammer and a 2x4 and call it good. Couple shots of Chassis black makes it all looks good again.

Good Luck tonight.
