Dyno testing a stock(?) 1972 440

LOL I really dont see how its a definitive answer that flow Trumps compression on this thread. The compression part wasnt even tested, just the flow.

Cylinder pressure is power, no matter how you get it. Low compression with high flow or low flow with high compression, the results will be about the same. But combined the 2, high flow and high compression and you will see the power go way up.

What is shown here is, you dont need a lot of compression to make REAL power. Its great info. Definitely one for the memory banks for the low budget guys that think they can not make power without compression.

Exactly. I just didn't want the bullseye on me for saying it.
The right combination will always make power. But the right combination for one may not be for the next.
Three 440s I'm very proud of were used shortblocks with headwork and "oldschool" cams. Two of them used 516 heads. All were pump gas. All used HV oil pumps and stock drives. One used the MP .528, tohers used Crane hydraulics. The most expensive was $1800 plus the cost of a running 440. All either equaled or eclipsed these numbers either on the chassis dyno or on the track. Two were mine, one was a close friend's and there were corners I cut there that I wouldn't on someone paying me to do theirs.
So cool test - but there's not much new here.
