All 80-81 Vettes with automatics had a TH350-C lock up. I have my original sitting under the bench.

If you are going with a crate engine, have you considered a stroked 350? I put a ZZ4 in my 73 a few years back and if I had it to do over, I'd go with the stroker.

I have seen plenty of mistakes in books.

Forget the tranny. If she breaks, it's usually something in the IRS. I'd spend some money for better U-Joints (Spicer solids) all around (drive and half shafts) and instead of the U-joint mounting 'straps', use the steel caps used on big block cars.

3" half shafts used on later C3's would be stronger than the 2.5 inchers used earlier, or go aftermarket.

A beefier leaf spring will help keep things more stable.

Those are a few bolt-ons that would provide some insurance.

The rest, I'd replace with better stuff as it breaks.

Agree with the above. Traction will determine longevity of the drivetrain.

You're right that it's wrong.

I don't believe a TH-350 was installed prior 75.
