Eric, From Dave: "Larry, Please tell Eric that the 8140 needs the GM style 1.80 ohm NAPA ICR13 resistor or stock GM resistor wire, and between 9.0 to 11.5 input volts with the engine running is correct for one. Accel 8140, 8140C, 8145 and 8145C used to be made here in the U.S., and were exellent coils back when, but...sometime in 2003, productiuon was moved to Taiwan (profit margin on sales was the main reason), and the quality disappeared in them, this is why the tech told him that the coil can explode on full battery voltage inputs. And, that running one with the Crane system WILL NOT RAISE output voltage to the coil, as the Crane system doesn't have the electronics and drivers to pump the coil output up any more than what a stock set of points makes. If it were me, I'd use these coils, all but one are U.S. made Andover coils, the place that used to make the Accel stuff... MSD 8200 only Summit G5215 Exact same coil as the MSD 8200 NAPA IC12 All above are made on the SAME line at Andover And a Made in Mexico coil that is of great quality and same specs as above, CarQuest 26189 Good as well are the Crane PS20 PS40 PS60 Best regards, IgnitionMan"
Thanks Again Larry. I have 11.46 with the car running at the coil, but 12.40 with the key in the on position with the ICR13 in the line. I guess until I get one of the better coils I just need to make sure I dont let the car sit with the key in the on position for any length of time. I'll get ahold of the local Napa and CarQuest and see if either of them have anything in stock. If not, I'll order one of the coils. I only went with the Xr-I so I could ditch points, the hotter spark probably came from replacing old, worn down wiring and points. Ultimately I'll do the HEI conversion, but unfortunately money flow isn't good right now. Thanks again, Dave and Larry :TU:
The other half went towards springs that I needed desperately, and a matching seat cover, and a new carburator... Hence why cashflow is in the wrong direction. This fall/winter, I will have an HEI Conversion :TU:
