Eric Weingartner LS Cam Challenge

[Stan Weiss]

How did each of the cams that were tested with the different heads, intake manifold, headers, and increased CR do?

My understanding is at the up coming PRI show, a number of the people who entered a cam in the challenge will be there in a conference room talking about the cam challenge. I will not be at PRI, but maybe if are you could stop in and to get a better idea of how they made their cam selection.

I currently plan to attend PRI. I missed the first one in nearly 30 years in 2022, while I was recovering. Don't intend to miss any for a long time. I plan to sit in on several seminars, they're often quite good.

As a followup. I find it interesting how at around 4900 RPM almost all of these have the torques come so close together.

This was at PRI. While it is about Eric's Cam Challenge. There is some good general engine / cam information discussed.

Near the end of this video Eric shows the results of testing the Victor, Victor Jr and the Holley Split ported by Charlie Servedio. Using the Brodix BR3 heads and the Texas Speed cam.
