Switching to HEI???


  Hey guys, if I switch to HEI in the 68 GP, What wire do I hook up and where.  Is there any difference in the years of HEI  I would need? Its the original 327, 4bbl.

 

  Thanks,   Ken

The power wire on the distributor (I think it says 12 volts or something like that) needs to be a fused 12 volt wire, preferably from the fusebox, not the 9 volt wire that feeds the current ignition coil.

Yes, "ign fused" from the fuse block.. I believe in '83-'84 they went to ESC (electronic spark control), so stay away from them... One wire to the "B+-Batt" terminal and you will be ready to go!

Bonus if you have a tach as the "TACH" terminal is along side for that as well!!!!

Just make sure that the "new" 12volt source is "powered' by the ign. switch & not "direct" from fuse block or the HEI will not shut the engine off by the key!!!!!!!! I did run my Catalina with " Crane" electronic conversion off the old source [9V] for awhile but changed over to 12V source. 52 Torpedo Back has HEI, works well!!!!

remove and replace the resistor wire from the coil to the bulkhead connector

it is 12 volt feed from the interior side of the bulkhead connection

Thats what i do too.  I have lots of new GM  "twin-loc"  wire terminals,   so i just pop out the resistor wire and replace it with a heavy red wire.

That way it looks like a factory harness.
