I just watched an episode of Power nation. The engine in question was a 302 ci flathead. 65CC heads, block was relieved, and 3 94 carbs were installed, No Cam specs were mentioned Power was just shy of 160HP torque 267 . No RPM were called out. Kinda makes you wonder where all these 200hp flatheads come from
 
They're very small horses.


These are the same horses that live in 500HP 350s and 450HP SBF 302s.

I saw that program also. For what they did to the engine, which was almost nothing, the dyno readings were very honest.
 
I Wonder what cam they used? When JWL modified the stock engine, it produced very little HP reguardless of all the add on, untill a mile cam was installed and that helped allot. Most of the 276 Street engines i build only produced 130/140 Hp @ 42/4800, But this was more than double the original.
 
Been watching allot of LS and LT builds and the new aftermarket alum heads for the old engines. It seems that the biggest modification is the elinination of the bowl under the valve and blending it into the original port. JWL did something like that. Some thought should be given to this.

Did JWL ever publish the final power figure of his engine? I'm curious how it compared to the stock and mildly modified 8BA described in his book. I'm not curious about a final number as a true horsepower figure due to differences in dynos as described in his book.
