63 Dodge Dart, now let me see;)
Now you have my curiosity up.
It's been 6 months of running around town here in Palm Bay FL, about max 45 mph unless out on I-95 then it's about 70 mph.
Checked the plugs tonight as the sun was setting after a run this afternoon with the '89 D100 318 4 bbl and Mopar HEI and E-Core coil.
Been 6 months since I last looked, figured they would be burning black by now. Nope, burning nice and clean, tailpipe clean too.
NGK GR4 plugs gapped at .050 ths timing set at 8° BTDC
No wonder it runs so nice and is so responsive.
Happy Camper
