I'll try the SMP blue streak and see how that holds up, at least theyre cheaper but appear to be American made (I hope) per the website. If i can get multiple trips out of it i expect the next move to be Daves coil. Thanks for your help everyone. Out of town for a week but stay tuned.........
Whatever coil you get weather is a genuine GM t.i. coil, repro chicom t.i. coil, or even one advertised as a t.i. coil. you must measure the primary resistance. It needs to be 0,41-0,51 ohms. Anything else will puke the module. I know, I went through 3 modules a few years back. Finding an ohm meter to read to low is not hard- I use a $15 1940's Simpson I got on ebay. One thing I have not seen mentioned: verify the module ground to the rad support is clean, tight, and has a star washer under the terminal

In my case- no spark. With the wrong coils installed, the engine would run for a second then would crank over with no spark. Changed to another coil and a another new module, same scenario. Another new module and a GM t.i. coil and all is well for the last few years. That said, the next time, I am going with a run of the mill GM 4 pin HEI module. The HEI module will work with any coil.

well i received the SMP blue streak from rockauto.........the one that crossed to a TI coil from Delco #, per the other post. Dave Fiedlers ohm test confirmed it was a standard points coil. Not gonna bother with it, sending back and i bit the bullet on Daves coil......sending him a check. Im hoping to have the same luck you've had. He seemed confident it was not the amplifier based on my history, just everyones junky coils for sale.
