You're 95% correct. The problem is almost everything Nick builds makes about 400hp--He can show you how to build a 400hp 340 and he can also show you how to build a 400hp 440. Until the supercharged 440 episode I honestly started thinking Nicks dyno was broken and "stuck" at 400hp--LOL Nope . I guess he is in his wheelhouse building smallblocks and bigblocks that seem to make around 400hp. Yes there are a few exceptions of course. J.Rob

I think Nick realized that, I've noticed some of his more recent dyno videos are of hairier stuff. Recently did a 600hp BBC iirc and an aftermarket cam comparison in a Pontiac 455.

Seems like his clients in Canada are more interested in stock-type builds for reliability and cruising as opposed to high-power builds for racing. Most of the cars in his shop are high-end restored muscle cars, not so much home-built hot rods or race machines.
