Here's a cool little 273/292 build for the 273 guys.

I would say it’s a pretty optimistic dyno. That cam and let’s say 8-1 compression I would say they are lucky to break 300 hp. Kim

I like how every time something doesn't fit with peoples preconceived notion it must be a lie.
Why would this engine builder lie, is a 360 hp 273/292 gonna sell them a ton of heads and crate engines, sure they could be.
