... so if i ordered this http://www.ebay.com/itm/330830750870 what else would i need to get. i have an ignition coil that is black with a chrome bracket. ..
I bought the same HEI distributor from skipwhite, plus the e-core coil he offers (read his listing). To get full benefit of HEI, you want an e-core, not an old round oil-filled coil.
After-market e-core coils are usually easier to wire, but you could use a factory one if you grab the matching cable at the junkyard. Ex. Magnum engines have one at the front of the head. I am thinking of replacing the 4 pin module in mine with an 8-pin module going to a GM cable to the GM coil. The 8-pin will let me control spark timing with the Holley Commander 950 ECU I plan to add.
