M21 with overdrive. What's that, one of those Gearvendors?

Gear vendor units bolt to the rear of your trans after you remove the tail housing.

BTW, it's the tranny you get when you buy a 4.10 rear gear and find out you should have listened to your friends that said it was too high.

I understand. but it should have nice power thru the gears, especially with the 409

The 454 is the one with the 4.10 rear. The 409 has the M22. I like it but sometimes wish I went with a 3.73 over the 3.55 I don't race my cars so the 3.55 is good enough for the streets.
