Metric 200 - What do I need to make one last

KennyAnderson · 06-01-2020, 03:46 PM

Good Afternoon guys. It's time to start converting our 93 Z28 IHRA pure stock car over to be NHRA legal. Car is 90% ready it just needs a drivetrain. I already have a motor, next up is a tranny. Of course I had a good TH350 that I sold recently.....DOH! I also have a Metric 200 but it's bone stock. I have a few options for tranny builders but I wanted to pick your brains a lil. Other than the obvious, manual valve body, deep pan, etc. What do I need to make this thing live? It will get beat on as we bracket race... A LOT! LOL! Does it have the same input and or output shafts as the TH350? I have a good ATI converter for my old TH350 I'm hoping to reuse?? Also do I need a different yolk?? Mounting points?? Thanks in advance!

I highly recommend Turbo Action. I have had a few different brands that didn't do so well.

You will need another converter. The mounts, driveshaft, and shifter will work. The tail housing has metric threads for the mount, so you will need new bolts.

If you get the rebuild through Scott McClay , he has an option to get you a 350/400 turbine shaft , and revised pump . That way you can use your current converter .

Get a J.W. Performance Ultra Bell. I cracked two cases before getting one. The case is the weak link on a TH200

If you don't go with the 350/400 changeover option, you still want to get a hardened stator support shaft insert.

Real simple Sepanek Racing Transmissions. I have 75 runs on his metric in a Big Block Chevy stocker. It's a 1970 402/375 hp making 635 hp. It's the fastest trany I've had in my car and it has lasted. BP
