Does anyone have actual power/torque figures for the various heads using identical short motor?

I know there's plenty of flow data comparisons, but very few of us drive around with a flowbench.

Thats hardly fair either as some heads with bigger intakes with work better with wilder cam etc...Say a Victor Jnr with std -sh cam would be crap at low rpm but with half decent cam it would power over most heads..Same goes with inlet etc.. Its horses for coarses....

is this what you are looking for? try the ultimate guide to ford 5.0L heads at the bottom of the articles page. may be slow if you're using dial-up tho.

they have flow results in parts 1,3,5 & 7, power & torque results in parts 2,4,6 & 8. each group uses a different motor to represent a different class for comparing similar heads. each group uses a larger motor than the one before it, each chasing a higher specific output and using wilder cams etc to do so. hope it helps.

Brilliant. That is pretty much what I was looking for. A couple of typos in the articles, but very well presented.
