Thank you, 40Ford for your effort to give some more background to these engines. It is really hard to dig up information about them. One thing I do not understand, what would be different from say a truck engine to a drag engine? I just wonder, because these engines make some 800+ hp on small cubes, and are sort of peaky. If opening the ports I would suspect they get even more peaky, and I would believe they could need more midrange power for launch? (Or a tiny converter?) Are there any other drag engines around at the same cubic inch that gives more power? (Except the high$ P5) I would think they could be ran as they are, "maybe" with more carb, cam and compression and a drivetrain to fit?
What I do know is that decamming them make for a much broader powerband, but cuts some top end power, but still way above in torque and power compared to other similar cube engines
