I have a question about witch coil will produce more voltage. I have the stock coils off my 99 ls1 trans am and coils off a 6.0l out of a 2003 2500hd. wondering if the voltage is different for witch one I should use on my engine. Any help would be grate.
Thanks -Will

Melco's are the best. Part # 12558693. It's been tested and confirmed to have up to 5kv more secondary spark.

I believe 01ssreda4 has a set for sale right now in the classifieds......

I would assume they would be the same since there really isn't much difference between a 5.7 and 6.0. But honestly it really doesn't matter unless you are making a ton of power and then you would probable want to go aftermarket coils.

The part number on the coils off the 6.0 is 12558693, guess I should throw them on. thanks for the help dr_whigham

Here's a good thread on it from a while back.

I actually have a set that should be hitting my doorstep in a day or two. More power... people ask why? I say how about why not?
