this site & slantsix.org-- are the 2 best resources.
what is wrong with your 1 bbl 48,000 mile car?
A well tuned 1 bbl should fit that daily driver bill nicely.
I drove a 1962 1 bbl valiant for years-- good acceleration-- great for a daily driver--- took my son to many a ball game.
I put on a great condition carb-- tuned up a transplant 225, petronix ignition, larger exhaust & drove it, it is still driving today on this same combo.
