Re: 5 speed

Another option is to use a saginaw 4 speed out of a vega or monza. Thats what I did and I ran a 2.73 axle ratio. The saginaw with 3 rings on the input shaft are geared at 1st=3.50, 2nd=2.47, 3rd=1.65, 4th=1. The gear spacing is very nice and even with the 2.73's it seemed like 3.73 of the line but like 2.73 on the highway. Alot of people say the trannys are junk but mine has held up to a mild 350 for 5 years and has even been holding up to a mild 454. With this trans 1st,2nd and 3rd aregeared very close and 4th is a little farther it feels just like a overdrive.
