Anyway, back to what I was asking......basically reliability and value is what I am looking for. And to use with thunderbolt ignition on some mildly modded 509's

you could replace with the mercury coil at 73.69 each,or you could use the msd high vibration coil at 47.99 each,the msd coil will last forever and won,t need to be replaced again.from a value standpoint,the choice is simple math.the fact is both choices will performe the same,but the oil filled coil merc sells will eventually leak and need to be replaced,he msd coil contains no oil to leak out.

You guys do realize he just does this to get a rise out of you right? |
stevereno is a ignorant moron,he did not hit a nerve,i just dont take kindly to insults from a POS like him.he cant be taught anything because he knows everything,just ask him!i think he believes his own bullchit,after all ,he did say he has experiance on every engine from every manufactorer in the world.:lolhit::lolhit:he needs to put down the crack pipe:bong::stupid:

OK...sooooooo you don't like steve whoever.....got it......Will the high vibration coil from msd work fine with the merc ignition? I am sure it will work but I never gave thought to the resistance and what not that was mentioned here......
I personally have used msd boxes with nothing but bad results as far as being reliable, but if the coil is good then ok. |
ya,the msd 6m box seems to be junk,i think they are importing them from china,i have replaced several leaking merc coils with the msd high vibration coil with no returns,one of them was about 10 years ago.msd has a coil identical to what merc is selling,but it is still an oil filled coil,allthough it is one third cheeper than the one merc sells,you cant go wrong with the msd high vibration coil.

Sounds good, I think I will pick up a pair!!
