1972 street strip swinger
well since getting the motor in and running I wiped a lobe on the 590 cam. so I switched to a 557 cam, put in a firecore distributor, switched to .039 felpro head gaskets making it 10.4:1, painted the car, and have been out driving. most say that's too much compression for pump gas and iron heads, but I put 5gal of 93 in it and no sign of knock or pinging, still have some carb tuning to do but hopefully to the track soon!
