3 to 4 Speed Conversion

I have a 3.09 first gear 4 speed, and I tell you what, I love that first gear 3.09. lol Excellent pull ya out of the hole gear.
Works real good with 3.55s, and not too bad with 3.23s if you got a bit of a torquey engine. But if you have an 8/1 teener with a 268* cam ;well.......... it's probably better to have an automatic and a big TC.
