I think it would be a better test at 500”, with a combo where the TF heads were making well over 600hp.
Something that can really illustrate how much power the milder heads are leaving on the table.
Was there any attempt to equalize the CR between the various heads?
Or was the CR difference part of the power difference?
It all depends I guess. I like that they tested a stock stroke engine with a street size cam. Both the test you suggested and the one they did can provide good info.
