will a super t-10 hold up behind a 440c.i. with slicks or dot tires.

I broke mine with a 406 and street tires! It will last a little while, but not long! My roller bearings between the input shaft and main shaft were destroyed and locked the shafts together effectively locking it in 4th gear! I limped it home and replaced it with a Tremec TKO. No problems since!

The closer ratio units are strongest. They can be very strong if you get a nickel input shaft (main drive gear) and cluster gear. I had a friend with a 68 Firebird that ran one of the 2.64 ratio boxes with nickel input and cluster gear and used to dump the clutch at 7,000 RPM with slicks and would run 10.76 without any breakage.

If the 7,000-RPM part has you baffled, that is because I forgot to tell you he had a 427 Chevy. Actually I was afraid to say because I didn’t want to cause any undue stress or pain for anyone. I can tell you that I did give him hell when he switched from his 428 to the Chevy.

Prior to installing the nickel gears, he did break the Super T-10's main drive and cluster, but after installing the nickel gears it held up and never broke again. The only bad thing about the nickel gears is that they are soft, which gives them their high-impact strength, but does not lend good long term wear characteristics.

Here is an excellent website with some really good info on the Super T-10. Look at the application matrix and note that the ratio can be identified by how many grooves or rings are cut across the clutch splines of the input shaft. 2 rings indicate that it is the closest ratio version with a 2.43 1st gear and the 6-ring model is the widest ratio version with a 3.42 1st gear. Also note at the bottom of the matrix the Richmond Gear units are listed with their torque capacities. Notice the nearly 100 Foot Pound difference in torque capacity between the close and wide ratio units. I don’t know if the Richmond units have the nickel gears.

B/W made a iron case with hi nickle 2.88 gears.When I talked to a Richmand tech rep he told me that was the strongest ST-10 made.FYI,tom

Yep, if it has 4 rings on the input and a cast iron case, that's the one

I broke 2 of the Alum. cases with a mild 455 and Drag radials. Cracked the case down both sides. Got one with the cast iron case, and had no worries after that. They will show up on racingjunk.com now and then. I got 2 of them from there for me and a friend. $600-800 depending on who built it.

Back in the 1970's I had a 66 GTO that ran a best time of 11.31 using a 2.88 first gear, iron case and a steel midplate (never broke). I still have the midplate if anyone needs one.

Bob, I would be interested in the mid plate e-mail me at [email protected]
