Your RIGHT. The dyno sheet is being sent over. This is a customer's motor. Mine will be a bit more than this. BUT IT'S MINE AND IF THE "052" ZL-1 BLOCK WILL HOLD IT, it should make substantially more Hp and a bit more tq.
Now guys want to talk about VE (Volumetric Efficiency), well my OTHER motor is just over 120 V.E. It's under 500 C.I. and DID make 1274Hp and 824Tq. As you can see, we too can make power.
YES I too know Mark Jones and have spoken too him on a few occasions. Mark does well with those 496 combo's. We too have 496's that not only make over 700hp, but have run couple thousand miles all the while getting some fuel economy. But we use sq port OEM heads and OEM intakes.
