MSD coils are pretty much junk and don't last. If your not having any issues with spark blow out or your not on a bottle you won't see any gains really. Leave the stockers on there, they are plenty powerful for 97% of people and are a good coil. Spend the money elsewhere.

yes, truck coils with the number d585 and I believe they come on 6.0L and larger. They have heat sinks on them. They make startup easier and most people fine hp/tq gains.

Honestly I didnt see no improvement going to the MSD coils. The only improvement I seen was replacing the dead, low spark, cracked casing MSD coils back to stock.

just to put things into perspective, w/ my truck coils I dynoed 350rwhp/362rwtq SAE! I have seen several cam only cars that put out lower numbers than mine. I have a bone stock engine. Just boltons.

uhh I dynoed 349rwhp and 367 tq with headers/tune..... that doesn't put anything into any perspective..
If your car is a high mileage car OP then you may see a slight increase due to a renewed stronger spark coming from the 6.0 coils. Look at the thread where the guy gained some 18hp or some ****, the car had high mileage... some report no gain. Any your going to have to dish out more money to have ur tuner put the dwell time tables in and all that jazz.. it ain't worth it to me personally

SAE, which produces the same numbers no matter what time of year or the temp for a given set of mods levels the playing field. apples to apples
STD is inaccurate because on a cold day it looks like you've got way more power than you had than in say the summer of the same year. apples to oranges to potatoes. You can get a million different dyno numbers as long as the environment keeps changing. SAE corrects for all that and makes the numbers comparable. Thats how it puts it into perspective.

yes the same dyno helps, however look and 99% of dyno charts, same car, same, everything, 30 seconds later and will experience a diff. number. its not uncommon to see a 10hp diff. in your 3 pulls on a dyno, SAE or STD
