Does this sound right

The heads have just as much to do with peak rpm potential as camshaft, I'd even say more so.

Is that Canadian HP or US? I wonder what the conversion rate is.

my 436'' W2 peaked at 6900. i'll try to find some dyno sheets.

Some run out of breath before it runs out of cam.

and I'd say the intake as well.

IME it is the cross section AND the shape that dictate 90% of where peak power occurs. The other 10% are camshaft AND exhaust in conjunction with each other. I've seen an NA 1st Gen Hemi with a cam and only 220 @ .050" peak at 6700 RPM. J.Rob

Takes less cam to make horsepower and turn rpms with properly sized ports and intake for the respective cubic inches.

Great, thread. I've learned something.

I didn't get all scientific, but yea. lol

Yeah, that made sense to me

Thru the years, I’ve tested a few combos that surprised me in terms of where the peaks occurred.

Some higher than expected……..some lower.
