Trick Flow 240...

My 470 made close to 720 hp with the 240 heads. That is a pump gas engine. Here is the article from Hot Rod: We Test Intake Manifolds and Carburetors on our 400 Stroker in Search of Ultimate Power - Hot Rod Network

I'm in the process of dropping this 470 into a Duster. The Duster is a bit of a project car so it will be a while before I'm on the road with it.

Hi Andy, looking at the pics in this article, what valley plate is that? It looks like it covers the valley only and you can change intake manifold without disturbing the valley cover. I’m in Australia, where could I get one from? Thanks in advance
