Great info on alternator all....thanks, and for wiring diagrams too! I'll have to do some wire tracing on the ign. switch. Hartrod I am running a Painless Circuit Boss (7 circuits) for all my "new" circuits to keep them off the oem wiring until I repaint the truck...and do a complete rewire. Fuel power comes off the efi stand alone harness and has its own relay.
Brew those total timing numbers seem low? are they for boosted app or n/a? I thought I saw 40* (or maybe even 45*?) while watching my Aeroforce ScanGauge, while hooked into OBDII, coming from my stock LS2, in my TBSS in coasting conditions. Under 30* seems really low? Weren't SBC's like 32-36* or more for total timing?
I asked because my LY6's current tune has as much as 50*?
