the last dyno session i tuned our car on only gained about 6hp from the last session but it had more torque across the entire RPM range, despite marginal peak gains.
Playing with Desktop Dyno (for what it's worth) shows me a much better torque curve with the 294/300 duration cam vs. the 300/300 duration cam. The 294 cam had WAY more torque in the lower band and kept a much higher curve across the chart. The 300 cam has a high peak HP, but the curve just doesn't seem to hack it. I'm probably going to go with the 294/300 duration cam and 1.6 rockers. That'll give me damn near .600" lift and a better torque curve to boot.
0HP930: The motor had a stock cast iron crank, so I'm moving up to a cast steel crank.
Here's a couple of screenshots of the Desktop Dyno screens:
