In the late '70's we had a '68 Mustang that we put a 70 Cleveland into. Weighed 2800 when done, engine had no super mods, just a good machine job, Gapp and Roush prepped heads, Crane hydraulic cam, Torker intake with a 750 Holley, headers, good ignition, Top loader 4 speed, and 9 inch rear with 4:88's. It ran low to mid-11's with those simple mods. That Cleveland converted me to being a Ford fan, they can be built to perform very well, and on the street I surprised a lot of BBC's.

The '70 4 barrel would be a great engine to pick up IMO.
