"Cool Can"
A friend of mine once showed me his little trick, a 'cool can', basically an aluminum can that shielded the fuel line. Said it gave him more power. Seems to be a little opposite from our 'heat the fuel' ideas.
The motor was a built 340 so perhaps dumping more fuel into the engine did get him a better change to burn more fuel/have more combustion.
Speaking off....when I was out at a cruise night with my friends MP Crate 360 78 Aspen, when he started it up it rumbled nicely, but I noticed that if you put your hand around the exhaust, you get quickly covered with 'black stuff'. He said this is 'normal'. This is another 'built motor' and runs a Demon Carb on it.
Now, what I'd like to know is how to 'fix' that. Can it even be fixed on a carb'd 400HP car with something simple or would one need to completely rebuild the carb and tune it to the max?

Singh Grooves and/or PowreValvz. I'd go with Singh Grooves since it's a "free" mod.
Many, if not all, "built" engines with their big camshafts and high compression lose a lot of power/fuel out of the exhaust due to overlap and duration. It is so prevalent, in fact, that the guys at the 460Ford Forums recommend "bigger" camshafts for monster compression engines (13 to 15:1). They say it "bleeds" the compression down. It makes sense, but is a terrible way to "allow" you to run high compression (they don't believe in edging/grooving/PowreValvz/PowreRings/PowreLynz).
