I miss the old days where you had a good used engine- tore it down, cleaned it honed it and did a farmers rebuild with new rings, gaskets, bearings and oil pump. Hand lap the valves,crane cam and springs, new 4bbl carb aluminum intake, headers dual exh with turbo mufflers and you were the hero of your town. (Yellow plug wires and big Accel supercoil) Closest we could have to that presently is a good running 318-360 from a Ram pickup and rebuild it.
