If you want the best mileage, the lowest ratio [numerically] will provide that, if you haul or tow, you want a higher ratio. Let us know what truck we're talking about, and we can probably find out what ratios are available, hope that helps. | | | | | Joined: Jan 2008 Posts: 14 New Guy | | New Guy Joined: Jan 2008 Posts: 14 | the truck is a 1964 chevy c10 short fleetside. i will not be towing anything with this truck. i will also be driving on the freeway daily.

That would approximate what GM put in a car with that engine. | | | | | Joined: Jun 2004 Posts: 8,597 Riding in the Passing Lane | | Riding in the Passing Lane Joined: Jun 2004 Posts: 8,597 | It also depends on tire size. I'm with Moneypit, something in the 3.55 ratio.
They say money can't buy happiness. It can buy old Chevy trucks though. Same thing. 1972 Chevy c10 Cheyenne SuperIn the Gallery Forum | | | | | Joined: Jan 2008 Posts: 14 New Guy | | New Guy Joined: Jan 2008 Posts: 14 | thanks for the help guys

would a 55-62 3.38 ratio work ok? i was just looking at the jim carter catalog.
or would i be better off keeping the 3.73 ratio?
thanks
