Attempted to fire my motor for the first time

[Low69CST]

I took my first shot at it today. It was also the first time I had juice through my painless kit. I was suprised the thing didn't burst in flames. But I did have a problem. My truck would cut off as soon as I took the key went from the start spot to the on spot. I wired the truck exactly like it showed in the book. To get around it, I wired my HEI straight to the battery. The problem didn't make that much of a difference because my carberator was gummed up (an old Holley my dad had). So it would only run on the gas we poured down the carb. I did get to hear it run for about 5-6 seconds at a time. Its alot meaner sounding than I thought it would. Also, its loud as hell. I have my 3" duals and 40 series flowmasters. I definately won't be able to speed much. If the cops can't see me they'll hear my ass!

Anybody had a simular problem with the ignition cutting off on the ON position? Might be a bad switch, but I wouldn't think so, worked when i took the truck apart, but then again, that was like in '96.
