Hi

I have a 1961 Buick 215 engine. I am considering installing a T5 1352-072 transmission from GM 1985 Camaro/Firebird 5.0 V8.
Has anyone used this combination? Are there any common issues to look out for?

Thank you

A Buick 215 mated to a Camaro T-5 had been done many, many times. Your T-5 is not a World Class T-5, but that really makes no difference for you application. That tranny will do nicely with your stock B rearend.

Good combo, but the stock 3.90 gear is too much for the street.

Why ? With a .63 5th gear it yields an effective rear gear ratio in 5th of 2.46

Isn't 1st gear all but useless? Drag racing maybe, but for the street I'd prefer a 3.50:1.

John, The Camaro V8 T5 has the 2.95 first. Makes a more useable first. I think you are confusing it with the V6 t5 that has a 3.75 first.

Yep, V8 T-5 does have better gear ratios. And a 0.63 overdrive will make interstate cruising very comfortable.

I am using the same setup with the original MG 3.90 differential and stock brakes. No problems. It's a good combination of power and highway cruise.

X2...I have a newer T5 with my 3.9 Rover but the ratios are the same. Actually first gear is fine and very usable off the line...the 0.63 is definitely an overdrive even with the 3.9 rear end. It suits the vehicle well but I DO think a slightly higher 4th gear would be be nice as it's a big gap between 4th and 5th. Still....with a light car and tons of torque it really doesn't matter!

Yes, it is. That is why the stock rear gears can work on the Interstate. If I ever get around to swapping in another rearend, I would use the 3:50 gears that John H. suggested & convert my .63 5th to a .73. to close up that 4th to 5th gap a bit.
