Rebuild 318 or go Crate

It depends on the model year as to whether it needs lead in the gas. It if it a 73 or newer I believe, it has hardened exhaust seats for unleaded fuel already. Maybe someone will correct me if I am mistaken about the year. I cannot be 100% sure.

Also, one more plus for the little 318. Mileage. The 318 out perform the 340 or 360 head and shoulders on mileage with a mild build. Smaller bore = less fuel burned.

For a good snappy street car that will be capable of some economy too, the 318 is really unbeatable.
