Base timing at 0 degrees TDC
848 head with hardened valve seats for unleaded
don't know compression ratio or if head was milled or block decked, shop owner retired so no way to find out
temp gauge running at 180, 4 psi radiator cap, factory optional 5 blade heavy duty fan
running ethanol free 92 octane fuel
IIRC the distributor is a NOS heavy duty truck option but I'll check part number
