I wasn't dogging him. I just know that building motors like that isn't cheap.

JCisworthy, I'd still like to know what you think the restricting factor was in the rpm range, the heads would be my guess? Do you think you could have made similar power with a smaller cam since there is something limiting flow past 5300 rpm?
Thanks again.

I'd also like to know a rough cost of this build. Very curious.

Surprising results on the dyno, for me anyway

Customer wanted to try different intakes. Air Gap produced the best power.

John, I would like to take this opportunity to thank you publicly for going to the trouble to test these. I think there is a lot of valuable information (and surprises) there for people wanting to build a hot street engine. The Torker and Offy were almost identical through 4,500 rpm, when the Torker pulled away, and the Air Gap blew both of them away starting at about 3,500.

Good information for sure. 

I thought for sure the Torker would have made more on the other end of the pull than the Air Gap. 

The Offenhouser killed flow through the head on the flow bench and performed worse than the others

In this case the flow bench and the dyno showed the same results on the Offenhauser. Is that always the case, or do you get surprised sometimes?

The heads flow more with a Torker than the Air Gap on the bench. That is why I thought it would have made more power even at this rpm level
