    For what it's worth, the temperature on my Blaster II coil read 179 deg. F after an extended run in 95 deg. outside temperature today. I don' think I'd want to "wrap my hand around it" but the coil itself performed as it should.

    Long ago, I slipped two nylon spacers, 1/2 inch thick, between the mounting bracket bolts and the block. I did this when the Lucas Sports coil (that I never measured from the outside heat-wise) would shut down unexpectedly. I left these spacers in, even when switching over two years ago to the MSD Blaster II coil. I am also using the MSD Ignition unit, which probably adds to the coil heat. No problem so far...

    Let me know what the coil temp is on your unit, please. I was surprised that mine was as hot as I found it to be.

      I sure will. Plan on driving it to work tomorrow so I'll be able to give you that data. I know this much. Even after a long drive on a hot day now I can still hold the coil. I can put my hand on it and while it's hot it doesn't burn me. When I get home I'm going to add a photo or two of the way I set it up so it's pushed away from the block a little bit. And tomorrow when I drive into work I'll get you those numbers.

      Before I swapped it out the old coil was impossible to touch. And I was having terrible hesitation issues anywhere above or around 3,000 RPM.

        dicta Here's my setup. I used longer bolts with double nuts to lock everything in place, and hard nylon sleeves as spacers. All from Lowes. Takes some searching in the specialty fastener drawers. But it moves the coil away from the block.

            Exactly!

            And dicta , it was a cool morning drive (about 60 degrees out), but after an hour of driving up over the mountain, through town, some stop and go, traffic, etc...to work - measured coil temp with infared gun:

            116 degrees farenheit.

                Thanks again. I have a call in to Summit Racing, where I purchased my Blaster II coil a year or so ago, asking if I'm using the right coil. No answer yet, but said "they have a long backload of emails" to be answered. OK then...I'll wait. I
                There's no problem but it does run hot, between 166 deg. and 179 F.
