RE: Rear gear ratio

It won't let me upload a pic. It's taller in the rear end by probably 5 inches.

RE: Rear gear ratio

I can only imagine what that'd look like. It already has the muscle car stance!

RE: Rear gear ratio

What sucks about that, is that I just put new shoes on it!

RE: Rear gear ratio

I found a gear ratio / rpm calculator on line, and that's about what it said it would do, which is still a little high, but I'll settle for. Im just hoping that going from 456 to 373 isn't too much loss on the low end. I did look into gear vendors and it looks like around a 3k upgrade. Between the motor rebuild, exhaust, and new carb, I'm in the mechanical for alittle over 3k. Dollars are starting to stack up, and I haven't started on the inside yet. It's not in desperate need, but definitely needs updated. Exterior is in surprisingly good shape. Paid $1500 for it in unstable running condition.

Rear gear ratio

I bought a 24 ft class c 1976 Holiday Rambler (E-350 chassis) last year, and recently had the motor rebuilt (ford 460). I ditched the motorcraft 4350 carb, and went with a holley 650 dp. I had them install a bigger cam on rebuild. It absolutely has plenty of power taking off from a stop, or climbing hills with no downshift. The transmission is a c6. The good thing is that it's a c6. The bad thing is that it's a c6, and has no overdrive, which means I'm running 2700 rpm at 55 mph and 3150 at 65. It was built when the federal speed limit was 55, and geared for that. I'd like to put a taller rear end in it to reduce my rpm's at 65. I'm just looking to see if anybody else has been through this scenario, and how far is too far on swapping the ratio. I know I'm going to lose power on the low end, and at the lower end of a shift. I'm sure I can make up for any bogging down after shifting gears with a stiffer shift modulator spring to shift at a higher rpm. I haven't lifted it yet to determine what's in it now.
