OK, I'll chime in again. The major restrictor plate here is the heads. I think if we were doing a true comparison of this engine on a stock block motor we should be comparing Jesse's base numbers to the stock 2.5 and not the SVT 2.5 due to the flow characteristics. On my engine I think we should be comparing the SVT characteristics and stats more closely and then I think Demon should see the expected gains realized.
Also for someone who mentioned Bob King's car, he was running the smallest puley and it was tuned for total power when it was putting down the 290. He kept messing up the cross shaft and had to go back to a larger pulley after that IIRC.
