Kurt,
Yes I’ve read a few old tests where rev limits of 7000 or even higher were mentioned for 289s. These were probably accompanied by grumpiness at lower revs, but that being almost 50 years ago, I’m assuming that developments in cams / heads / carburation / fuel injection has made available better compromises.
One of my other cars is a mid-seventies Alfa twin cam (unmodified) with side draft Webers. This engine has stacks of grunt from not far above idle, and at the 6000 redline, it feels like it wants to keep going forever. My daily driver, an Australian built ‘cooking’ V6, is redlined at 6200, sees the redline at least once a day and loves it. That’s what I want in a 302.
Cheers,
Glen
