Back in those days, you didn't get 60' times. This was an 1/8th track and they did not have mph either. I had 4.88's and use to pop the clutch at about 6200RPM's and kick in the secondaries at the same time (mechanical secondaries). I'm sure it was way different than your setup. It weighed about 3600 lbs with driver, .626/310 cam, 13.6:1, 2" custom (nickel plated) "Headers by Ed" if you ever heard of them?, 1.88 exhaust valves, 4.88's, stock 4 speed 11.25 @120.0 was it's best. It would come off the line ahead of many faster cars but I could never get the mph up. It was a street machine.
