Is this a bad idea?
I ran a 833OD with a 8 1/4" 3.21 rear end, 195/70/14 (24.8") tires and a fairly stock 81 Aspen 225 Super Six on my '65 V200 wagon (originally 318/auto). Put '76 wiring harness, front end parts and disc brakes and dual circuit master cylinder, sway bars, extra spring leaf, 340 torsion bars, Tom Condren alignment specs, etc. Drove this combination ~340K mostly heavily loaded miles (work car driving around Oregon, Washington, Idaho and Montana with tools and parts) after the rebuild and loved every mile except getting stuck in Portland traffic from time to time. That car rusted away or it would still be on the road! As it is, I swapped all the good stuff over to a '64 V200 wagon with no rust and rebuilt the engine. That 0.7 overdrive means you can let the engine relax and save gas; I cannot even imagine this great car without the overdrive gear. The lower 1st is handy, too. I consistently got 25 mpg with this car, correcting for everything. Fun facts: The overdrive means the top bearing is working overtime. I always overfill a couple extra ounces of ATF in it. I had a stock '76 electronic ignition and my brother gave me an MSD 6A and coil which I put on; it was like adding a cylinder to the engine and mpg went up. I met a retired Chrysler engineer who said he helped work on the cam for the 833OD; "25 MPG, right?" he said. I used Ethos in engine oil and gas many of these miles, and always ran some kind of top cylinder lube in the gas. Synthetic lubes. Michelins run at 40-44 psi to account for the heavy loads; tire pressure should be proportional to the load. AM Radio Eternal Life: The factory AM radio has a killer tuner section that pulled in stations my tape decks couldn't even find. The main output transistor is ballasted by the radio light bulb; when the bulb burns out, the output transistor burns up and the radio dies. You can take the radio apart and find the transistor that let the smoke out and replace it with a super robust modern Si transistor (TO-220 case, I think), replace the bulb, and the radio is better than new. I replaced the original dash speaker at one point and got the dead bugs out and the fidelity improved.
