Has anyone used this Accel 300+ system and also the 375 programable? I need to upgrade the ignition parts and want to go with a multiple spark discharge but I am in the dark other than the MSD boxes. I would like to know if anyone has any experiance with this accel 300+ system by it's self and if anyone also used the 375 system with it and how the 375 system works.
I need to replace the ignition modual and coil on my car soon so I am just trying to get an idea of wich coils are the best and what msd setup I want to go with. This is going on my 383 with LE2 heads and custom cam. Turns about 6200. I have no use for more rpms yet. It is just a street car but I like my ignition systems to be hot and reliable.

just use a msd coil by itself and skip the ignition boxes. the msd box was worth 2 ft lbs and less than 1hp up top on my motor on back to back runs. the stock ignition being run last, so hell if the temps were different they could make identical power.

ok so the msd coil over the accel coil by it's self with no box? The accel coil puts out about 8000 more volts and the msd is 80 to 1 and the accel is 134 to 1 on the turns ratio but I guess from what I understand the turns actualy produce the end voltage so it is a moog point seeing how the Accel has more voltage. Do the accels have a reliability issue? What is the stock coil voltage output anyway?

you're making this too difficult. yea msd coil only, this was on a ~13:1 compression motor with a .030 plug gap. ran fine on e85 as well and thats harder to light off than gasoline.

I've had the Accel 300+ for over 10 years. Bought when they first came out with them. First one I had died after a couple of months and they warranted it. The second one has been on since.
