Jim Bailey... you're right about my hijacking of this thread, and for that, I apologize. But there are two questions that you responded to with answers that I think would be more beneficial if they were explained by you, on here (rather than in a PM.) Indulge me just these two issues, please, and I won't write on here, about this, again.

1. You said that valve springs are more an issue with alcohol cars than Fuelers. which is undoubtely true, but still has no answer for why they are banned by NHRA. They could save those racers TONS of money... like I said, they only have to be bought ONCE. What's the downside of that (unless you make your living selling steel springs...) I realize that YOU don't make the rules, but having "been there" in Professional racing, you have info and insights that we "outsiders" are not privy to, and I just thought you might have heard why this "no compressed air valve springs on ANY vehicle in competition" was enacted.

2. Is it not possible to use port (fuel) injection and keep nitro out of the supercharger on a T/F car? I agree that a nitro-fueled BOMB sitting on top of an engine that can have an intake valve hang open at any time is NOT a good idea... so, why don't they keep the nitro below the blower/compressor, so that the only thing in the supercharger at any time, is AIR? That would seem to relieve the potential for a monumental explosion by a significant amount. Of course, there could still be an explosion of the mixture trapped in the manifold, but the volume is significantly smaller, isn't it? It's such a simple idea, I'm sure multitudes of people have thought of this, before, so why don't they do it? I'm obviously missing something here; what is it?

Thanks for your time and the information you've posted here. I still wonder if your A/SA car is a Stage III motor.. I guess, if it's a '64, it would have to be...
