Got a 454 gen VI mag. gonna set ignition timing. There are two modules on the back of the distributor. the engine has a mild warm-up. bored .60 over to a 468 and has a mild cam. I did not do the performance mods. the distributor is mercruiser. I replaced the oil pump while i had the engine out for a gimbal ring replacement. I primed the system using the drill tool. so i had the distributor out.... I do not know which module is on the distributor... was gonna set it at 12 advanced and and call it a day. due to what i have on the mercruiser ignition curves advance in the 20-24 range giving me a total of either 32,34,36 advancement. are the modules the same across the board. cuz i have this chart attached. so i could set the timing at idle accordingly. on a mild setup would 32 advanced be a good safe place?

sound like im going down the correct path? what are anyone else's thoughts?

thanks guys,
Mitch

32 would be plenty safe.. But BBC's like lot's of timing

Only way to tell what the motor wants is to experiment. Just be careful to avoid the dreaded "D"

Get the number off the module, it should have the advance curve in the number

What did you set it at? I'm running the same engine pretty much
