Question:
How much difference do you think there is in acceleration (due to lighter weight parts) when you launch the engine at 7500 rpm, climb to 8400 rpm, drop the rpm to 7600 rpm, and then back to 8400, etc?
Weight and reciprocating mass might make a difference if you were talking about a 16000 rpm F-1 engine with a 3.5" bore, titanium rods, flat crank, that has to accelerate off the corners quickly and then reach max rpm.
So you are correct, there is a difference.
For a Pontiac guy, this discussion would be like discussing adding a tablespoon of water to Lake Michigan, did you make a change, YES, does it really matter at the end of the day? Probably not for the average pontiac racer that is running a 500+ cid engine.
