Ya, the 383 is sort of like a 340, stroke wise, if you don't have to drive every day on the freeway and don't care about gas mileage, go for the gears. I ran my 400 with 3.9s last year driving 25 miles each way on the freeway to the track and other places and just fine.
What rear gear???

Stroke of a 383 in 3.375, 318 & 340 are 3.31, and the 360 is 3.58. The 383 has a shorter stroke than the small block 360. I drove many old Dodge trucks with 360 and 4.10 gears with 30 inch tires. We had one that made multiple trips from Michigan to Arizona it would sing on the highway and only got about 10 MPG. If you truly want it to jump out of the hole and don't drive on the hwy much (at all) a 3.91 would really wake it up.
I'm going to a 3.91 in my V10 Fury but then again I have the OD ;)

If my numbers are correct, with my tires, at 3000 rpm, the 2.92 puts you at about 80 mph, the 3.55 at 65, and the 3.73 is 62, no sweat. And, when you put your right foot down, you do not want that little let down.
