Thanks for the kind words guys!
I'm really glad you got some benefit out of that article.

I honestly don't know the power handling capacity of these transmissions--I bought it used, had it rebuilt, and dropped it in front of my 290hp crate engine and beat on it for several years... 60,000 miles and it's still operating perfectly.

That said, I don't know WHY I'm still hunting for an iron case version, but I am.
Maybe to put in my '56 Chevy with the hot rod 283 I've got planned for it.

As for the OD ratios: Depending on the application, the OD ratios for a T5 are .86 to .73... and the .73 ratio versions are 4-cylinder mini vans. I believe most performance applications are .86:2 final.
