Today, dollar for dollar, is the 318 faster than the 340 ???

Yeah it would be a good showdown between a 5.2 magnum and a 340. I'm not sure a person can source a 340 very cheap these days. I have one but not going to build it for racing.

Lol I think this is how the 400hp thing got started

I started a thread a couple days ago inspired by this one a running 5.2l magnum vs running LA 360 but just cam headers 4bbl which one would be better for the thrifty shopper for /6 swap or roller car etc.. figured It's a decision more than a few have dealt with.

Magnum 5.2l vs 360 LA?
