Has any one put the MSD coils on there 5.7L yet? If so, do you see any differance in function,power,torque, or effinciancy?
Geting them installed this weekend, and was wondering if any one else has tried this set-up.

IME MSD coils produce over 2X the ignition voltage of stock coils--means hotter spark. To get the most out of the coils consider using copper core spark plugs with platinum tips that are 1 heat range cooler than stock. The spark plug gap can be .050 (stock gap). You may also want to assure that the engine runs between 170-185* to reduce the chance of knock retard. Lastly, you want to consider upgrading the big 3 grounding cables to optimize coil recharge time.

Thanks for the feed back.
I have the ngk shorties for the blower. Will those work? I also have a 180* thermostat, will that work too? Or do I need to change plugs, or get a 170* or 180* thermostat? It seems like you know your stuff about cars. Youe help is much appreciated
Using the NGK shorty as a guide (SRT8 stock), get an Autolite or Champion racing plug (copper core with platinum tip) that is 1 heat range cooler (this would be 2 heat ranges cooler than your stock RT plugs). Gap the racing plugs as stock (.050).
Because of the extra heat, get a 170* TSTAT (I personnally run a 160* TSTAT), and add 2 bottles of Water Wetter to your radiator overflow tank (if there's room). Using your Predator, change the fan speeds to 175* (low) and 190*(high)
At a minimum upgrade the battery ground cable in the trunk to an 0/2 gauge cable. The best setup is to ground the heads with 0/2 gauge wire, to reduce throttle lag, but you can wait on that.
I hope this helps.
