I agree with going over everything & put it all in tip-top shape. I would convert to 12 volts w/alt. & electronic ign. Once you start driving it you are going to want to gear it up for the highway. Going alomg at 50 mph with the engine screaming is not "comfortable" in todays traffic. If you can find a 4.11 third member it would be great but they are hard to find. A t-5 5 speed o-drive would work good behind the stock 235.
