All these Engine Masters engines have custom headers, intakes, camshafts, tuning etc. Doesn't that mean that it all boils down to a cylinder head competition of some sort? Perhaps they should have an OE Iron Head class? Keep in mind that these poly heads were designed for a 277-318 cubic inch engine! Does it really matter what some other engine/head combo can make? If we go that route all engines with a camshaft in the block are junk!
For those who want to say someone shouldn't build a certain engine type, you should really look into a small block chevy. They're cheap to build and can make about as much power as you want.
