340 stroker cam

Agreed, also consider at his current compression the RPM advantage is lost with the current cam, so the cam makes power to 7400 example, his engine runs out before 7400 is reached. So if he’s starting to fall off at 6800 what’s the point of a 7400 cam. I think we’re on the same page. If he pulls cam down to match current compression he most certainly looses the higher rpm that cam he has now is capable of, 100% correct, but since the engine runs out of steam before then anyway, he will make more peak power at 6800 with the smaller duration cam, than he could anywhere on the rpm range of the current cam. Those RPMs are for example purpose only.

Vice versa, pulls up compression, to match the current cam, he will be making peak horse power up at 7400. Resulting in more power than the lower compression with smaller cam, and even more power than what he has now with the higher duration and lower compression current setup. Yellow I think we’re eye to eye on this, just saying it slightly different. But same thing.

End of story is, pull duration with your current setup, you’ll make more power than you make now, but at a lower peak rpm. Or up compression to meet that cam and you’ll make even more power than that, higher up as the cam was designed.
