For your purposes I wouldn't worry much about making any major modifications. Just go with a stock rebuild, and maybe add a four barrel carb and manifold. The 068 cam is worth considering as well, Melling makes them these days and you can get them from Pontiac specialists, here's one source: http://store02.prostores.com/servlet/pontiacdude/the-1092/OEM-#9779068-Replacement-Camshaft/Detail For a serious performance engine, aftermarket rods are a good idea, but for a mainly stock engine the stock rods will be just fine. Talk to your machine shop about whether or not hardened seats are needed; if they're in decent shape now I wouldn't worry about them much. The Hydramatic is a good transmission. They're a four speed, and they lock up in top gear, so with the stock rear end ratio that was typically used behind them (in 1960, 3.08 or 2.87 ratios) they'll just loaf going down the highway at speed. There isn't that much benefit to going to all the expense to install a modern overdrive. They do shift kind of 'lazy' so you're not going to chirp the tires going through the gears, but that's okay for daily use.
