werd, thanks for clarifying... sounds like itll work fine then, just keep it tuned and youll be safe. keep your EGT's under 1500*F, measured 1.5" away from port, and your O2's richer than 12.5:1 and youll be golden.
btw, an 80 Elcamino?? and i thought my 79 Trans Am was a
ride. all domestics from the 80's really sucked ass, severely underpowered and severely UGLY. now... a 68 Elky, tahts what id do... its a Chevelle w/ a bed on it, and you could get the same power plant options, like an SS396, now thats something to reckon with. it wont turn, or stop, or pass a gas station, but it sure will haul ass.
