Hey y'all, I have a question and would like some input. I'm trying to decide if i want to run a 4 speed or 5 speed in my project car. The car in question will be a Model A on Deuce rails. The power will initially be from a mild small block Chevy with ~300 hp (more eventually). The car will see a fair share of time on the highway (road trips), but I will also run it at the drag strip on slicks from time to time. I currently have a 9" axle and a choice of 3.50 or 4.11 gears. With a 4 speed I could run the 3.50 gear and with a 7.50-16 tire I would spin about 2700 rpm at 70 mph. Not bad. I have a 4 speed with a 3.11 first gear now which I think would be a good combo, but I'm open to suggestions. With the 5 speed (T-5) I could run the 4.11 gear and see 2400 rpm at 70 mph. A little better, but I would also have one heck of a 1st gear. In fact, would first gear become damn near useless? I bet it'd be wicked with slicks, though! I already have the 4 speed (a Saginaw) so I'm tempted to go that route, but before I make up my mind I'd like to hear from y'all. Do you wish you had O/D in your 4 speed car? Was the effort to modify an S10 T-5 not worth it?
