Ls1 msd
Ls1 msd I switched over to a carb setup on one of my ls1's. Im going to get the msd ignition box. Do i need to buy a harness or does it come with the box? It says there is two different harnesses, but i didnt know if that was to run the box with the stock pcm and a trottle body. I no longer have that, now just a plain old holly 750. Thanks
i was going to use this one http://www.jegs.com/webapp/wcs/store...28917_-1_11191
I can use it for my nitrous and i didnt want to use the distrbuter, i want to compare the pcm to a carb setup running a wideband. every thing is the same except there is a 410 gear instead of a 390
