Glad you liked it, I thought more people would get that out of the article but didn't seem to interest people or they just didn't post about it. I agree a piston engine is a piston engine, although constant RPM engines (planes, boats, indy car) are a little different in design , cam head flow etc than out from stop to go type drag engines. Street strip engines that don't use a trans brake are their own animal in a way because they need to work from very low rpm to the top rpm very well.
That's where I like the turbo pontiac the best because it has gobs of its own torque and the intake tract can be tuned for low RPM and the Turbo actually raises its useful RPM band 1000 RPM therefore making it great from idle to top rpm.
All in all though you can pick up some great engine tips from engines that need to run at rpm for long periods of time and not break. Via tigon is probably the best example of this Ive seen.
