Within Stock rules???

Then why do all the newer combos (COPO, Cobra Jet, Drag Pak) go quicker when "gone through"?

So modified heads are the only way to make power? The engines are not sold completely blueprinted it is still a manufactured product. it's made like that so owners/engine builders can finish the engine anyway they see fit within the rules. Same thing that has been happening since the early 60's

There is no other way to improve a combo? Tuning, testing ect? Just do the heads and let it rip?

I never mentioned heads, or any other part(s). You said "These cars were build in a max effort capacity to begin with by a company that has every resource." and "The engines are not sold completely blueprinted it is still a manufactured product. it's made like that so owners/engine builders can finish the engine anyway they see fit within the rules."

Which is it?

That kinda depends on which side of the rules you want to walk on, doesn't it?

Not necessarily, I think max effort and the performance that comes with it is possible without crossing any lines regarding rules, but that's just my definition.

I mean head design, materials used like Ti valves and retainers. Cranks, rods, and other special parts.

I guess is what I'm trying to say is that the CNC program that is used to profile the heads I'm sure has been researched and pretty close to the best you can buy. IMHO.

I think unless you have spent time with one of these engines you don't realize how good the parts are that used in these engines.

These cars are all certainly "stock eliminators"!!

I've seen inside a few, whether good parts/execution were used is likely a matter of opinion, to each their own.
