 Subject: MSD Blaster ignition on 87 V6
IP: Logged
Message:
I installed an MSD 5900 Blaster ignition on my 87 Dak cuz I had to swap out the original carb for the non-feedback variety becuz the mixture control solenoid went south and you can't buy a new replacement and I still have to pass smog and I thought an upgraded ignition might help do that.
So then the stock coil starts getting super hot so i sprung for a Blaster 2 coil and now the damn thing (the MSD combo... I LUV my Dak) stumbles on accelerating from a dead stop.
I can use the MSD 5900 Blaster ignition with the stock coil or the MSD Blaster coil with the stock ignition and the truck runs like a dream, but not both together or I get a hair pulling, cat stomping, dog kicking stumble on acceleration from a dead stop.
My plug wires are about 3000 ohms per foot. I'm thinking maybe a lower resistance wire set, but then I realize that the plug gap has almost infinite resistance. Then I thought maybe I should wait til dark, fire it up and raise the hood to see if I can see where the electricity is going. Maybe I just need better insulated plug wires.
Thoughts?

Jack, I think you are on the right path, it could be the plug wires, 3000 ohms per foot is a little high. When I rebuilt my engine I replaced just about everything except the block and heads, my new wires only have about 700-800 ohms per foot and mine runs great, well for a V6 it runs great, I also get 18mpg around town, and 22 highway. I have 18,000 miles on it now and I was going to change my wires so I bought some Accle and they made it run horrible, so I put my old wires back on.
Good Luck
