Eco-Friendly Nostalgic Muscle...Is it possible?

[khansmith]

This is good stuff so far. Let me summarize results against the question posed "Could you build a "green" powerplant that looks and sounds like a classic but passes today/tomrrow's EPA standards? EX Could anyone build a 427FE Side Oiler engine (or an engine that looks like one) that meets today's EPA standards? ":

ROUSHAC: No Solution (unless you can travel back in time)
Aussie Mike: Yes w/ alt fuels, turbos & EFI
wtm442: No Solution (but believes modern engines will continue to grow hp)
Ronbo: Yes w/ expensive EFI, Exhaust, Sensors, etc (est $20K additional)

Please correct me if I am wrong.

I remember people switching to propane during the 70's. I know two old farts that still run it. The exhaust is clean, power is good. Must change the carb and of course a pain to refill. Much better choice than corn though. One of these guys live in CA, he claims that when he gets his smog check they can't believe how clean it runs. You also don't get all the carbon buildup and the engine lasts much longer.
