I need to know, from experience, which is the best ignition coil for a 1994 LT1? I've had problems with the MSD Blasters, so those are out of the picture! Any suggestions? Also, what is spark knock, what does it sound like, and how is the problem corrected? Any helpful hints would be appreciated.

 

I know a guy who used a hypertech coil for years with no problems....

 

I put in an Accel 300+ about 4 years ago and it came with a coil and both have worked flawlessly for me for 4 years.
I did not expect the ignition box to last as long as it has, I got 85k on it now.

 

I got a $19 oem equiv replacement at Discount Auto Parts 2 years ago. It's been doing the job just fine...

 

If you are against MSD Ignition coils than I would go with Accel.

 

Jaccobs Coil

 

I would use the Accel 300+ coil.
