Vortec Spark Table

Anybody know where I can get a copy of some spark tables from a Vortec 350 or iron head LT1? I've searched around the net for them but so far have come up empty. Thanks!

Low, what's your Main Spark Bias, Initial Spark Advance, and physical advance? I'm trying to get some idea what your total spark looks like.

thanks

Thats it, no bias, no initial advance, or physical advance. Also because of my stall I never really see high hi Kpa at below 2000rpm, so I didn't tune that a whole lot.

Those 6.3s in the high K/Pa low rpm area are used as the engine first begins to run, ie the first .1 or .2 secs. Not a biggy, justa FWIW.

Someone was painting black lines behind ya at the gas station. Tisk, tisk, LOL
