Does anyone have a recommendation on to which ignition coil I should get?

Had the MSD coil fail suddenly without warning after a few years, but otherwise worked fine.

I've read tests that showed that quality OEM coils put out as much spark energy as the aftermarket "performance coils". I'd just go genuine AC Delco.

At some point you need more metal/copper to store more energy in the ignition coil.

Within the confines of the stock form factor, the aftermarket is going to be limited in what they can do.

I have an MSD coil but moved it to the trunk wall....Dropped the temp from 160 to 120 (I also made an extra heat shield to block the heat of the cross-over pipe) Have had this since 2012....No trouble.

for an otherwise stock engine, there's no need to buy anything fancy. once you start packing on boost or high compression/RPM, then it starts to matter a bit more.

GM OE HEI is solid to 8000 rpm. AC Delco doesn't make coils for '80's vintage anything, it's all reboxed aftermarket. That said, Standard Motor Products supplies a LOT to AC Delco.

Can you tell us where you got the ignition coil plugs from? I have been wanting to do this, but I dont know where to get the right lengthed cables.

The coil wire is a MSD part, 18" long....https://www.summitracing.com/parts/msd-84039

Here are some better pics of the coil mount and the heat shield....






Sorry it took a while to load the pics; It requires that I >>PREVIOUSLY<< be logged in...But when I had posted and then went to edit, it stated that I was not logged on.....Tried 3 times....Computers, they will be the DEATH of us all!
