Re: Question for the guys running 3.73's with a 6cyl and manual trans
Hey bud, my truck is a short step but is a one family New Mexico truck that was more on the green side than blue originally and wasn't two tone. I kinda chose the color combo at the last minute last summer before I sprayed it.

I got stupid when I went back to college in mid-life, and decided I didn't need two vehicles living in town and I sold it to some kid. Later I saw it in the college parking lot and he had apparently tipped it over on it's right side I originally traded firewood for it. It came with a bumper sticker in the rear window that said: "Eat More Lamb - 50,000 Coyotes Can't Be Wrong"

Re: Question for the guys running 3.73's with a 6cyl and manual trans
how about putten a Saginaw 4 speed in. that would give ya an extra gear on those hills. but ya can't use the columm shift. I've got a couple 3 sp. overdrives and they ain't hard to find . but my 283 just barely has the power to really work one even with 3:73. GM never used any rear ends higher than 3;73 with the 3 sp. O/D in any vehicle

Re: Question for the guys running 3.73's with a 6cyl and manual trans
I think 3.42 is a heck of a good ratio for these trucks with OEM transmissions. 3.73 is wound a bit tight for non-OD, even with a six-banger. With 3.42s you could cruise at 70 and be turning about 2750rpm.

So I guess it calls for a series 3 carrier which does not cover up to 3.73 so you would need a new carrier. You could modify a 90s or newer chevy 6 lug rear end which are commoly found. in 3.42 then there goes originality so meh.

I used it to haul chain saws and gas, etc when I was working in the timber, so I didn't have to use the big truck or the "nice" K-10 with the camper. Then we moved to town, and I used the short step side to commute to work. I don't remember the gas mileage (~15 ???) but yeah - it was a heck of a lot better than the 1971 K-10 with 350/350 that was lucky to ever get more than ten Actually, the big GMC with the V-6 got as good or better mileage loaded down with logs (20-25K gross) than the K-10 automatic pickup

I just filled up - 2nd tank in a row to break 19mpg. $2.11 I think I finally have a handle on the tune. Truck is usable in all three gears now and I can maintain more speed on hills. I can live with it until either the trans blows or the motor does - then I make changes Trans blows - 3.73 and 700r4 engine blows - 350 / 700R4 3.08 rear stays put. |

That way you will never find a hill that you can't get started on I had a 1965 C-10 with the 230 and 4 speed and used to take it up jeep trails in Colorado
