Yes very interesting and eye opening.Only question I have is what about safety and $.If the vehicles were allowed to develop in response to competition with no limits wouldnt we see more people killed and see more of the one with most $ win?I am all for constant development but that drive for beating next guy is too much to resist.You would see guys with RetroRockets at the drags!
While I agree to a point, I think a lot of those questions would be solved by having to run current production engines. As manufacturers change engines, then it would be back to the drawing board. Plus, take the current Ford V8 (nicknamed "modular") for example. 4.6L (281ci) and 5.4L (331ci). The MOST these engines can be taken to is 324" and 380", compared to the engines Nascar is currently using that can be taken to 450+ inches. The engines NHRA uses can be taken to well over 700. Granted they are not allowed to run them that big, but when there is enough material to handle big inches, the engines are easier to keep together. Trying to make big power with a modular would be hard.
