Cylinder head discussion 340 with stock above deck pistons

Pittsburgh, Didn't we all run that junk back in the 70's when we didn't know any better, and we broke a lot of parts too. Just like torque converters have come a long way since then, so has clutch technology. I haven't broken a part in my 4spd street Dart in at least 10 years and probably longer and it leaves with the wheels up more often than not, nowhere near as high or as quick as your car, but mine is a streetcar on 9 inch slicks, not a full on race car on 14 inch slicks.
