422 dyno fail

I’ve mentioned this before........
When the engine makes noticeably more TQ than HP........when you break it down to basics....... it’s running out of air as the rpm increases.
Induction, head flow, head size, header size, cam area....... and usually, it’s a combination of several of those.

For NA street/strip type builds, when you get into that 1.25ft/lb per ci range, it’s not that easy to make the TQ go up significantly.
Shifting the tq peak up in the rpm band, along with trying to get the curve to fall off slower is what I usually attempt to do, when the tq number is decent, and the HP number falls a little short.
This usually comes at the expense of street manners and low end tq.
