northdm,Drove many strictly stock 283s in the 50s They were always reliable and economical to run. Points and plugs and an oil change every so often kept them happy. I chose one for my 49 Sub because I didn't want a godzilla stroker, hemi, 454, 600 HP, crate, etc,etc motor. At my age I have pretty much grown out of the go fast mentality although I must admit I occasionally have to fight off the urge to squawk tires. A TH350 or R4 behind a stock or mild 283 will give all the performance you could want with reasonable mileage. I built my Sub for a reliable cruiser/daily driver and it should be able to keep up on the Interstate. It sounds like we are thinking alike. Good luck on your project and build it like you want it however that me be. Its your truck.
