I found this on another Website, and would be very interested in reading more about this, but can't find it...
In a very thorough 292 dyno test over on Inliners. We tested (8)different cylinder head combos in various stages of porting and valve sizes. 300 HP will be very easy for you to achieve. We started with a bone stock 292 to establish a baseline, and even in bone stock trim(160 HP) yielded 300 ft. lbs of torque right from the 1800-2000 RPM on up in a straight line across the RPM range. One of the best combos we recently dynoed made 330 Ft Lbs of torque and was 300 HP. The RPM was well below 6000. The torque curve was almost a straight line from 2500 to 4200 or so. I looked at the Engle link, but didn't which grind you were meaning specifically. I'll look back at some of the dyno sheets and see what cam we used for the best peak HP and TQ #'s we got.
Thanks again.
