Just wondering does anyone use it? I know with a Turbo or SC application it is a must but what about straight motor? if so are you using a MSD Opti.

ya MSD6AL will give you better spark, youll more notice it at higher RPM range, stronger spark.

BTW, if you plan to get one, i would recommend the harness for it, wont have to splice any wires.

im using it with stock opti

Got one on mine, I didn't notice a difference in performance with it alone, but the rev limmiter is added security. Not to mention the 2 step, it's lots of fun!

I have the addapter for the msd 6al, are any of you guys mounting them anywhere else besides the inerfender next to the fuel lines and fuse box

I was gonna mount mine in the glove box, but the instructions were specific about not mounting it in a confined unvented area so I just put it on the fender.

I have mine in the glovebox and drilled holes from the rightside of the glovebox and fed cooled air to it from the AC duct. Highly recommend the harness kit, I spliced mine just recently had problems with the box dropping the spark signal to the coil. Pretty frustrating, I had to disconnect the box in order for her to run so I could ship her to Hawaii.

Mine's on the passenger floor, I didn't like it under the hood and didn't want to drill in the glove box.

I did not use an MSD but I noticed no gain when I added an Accel 300+, like one poster said above I have kept it because I like having a spark based rev limiter on the car.

MSD opti is vastly LESS reliable than stock, though some who made the mistake of buying it will swear by it even as they tell you how to completely rebuild it before you can use it.

i had the 6al and a nology coil, and i was all motor. i have always used and believed in factory AC Delco optisparks, and thats the whole unit, not just cap and rotor. get the vented style. if you got the nonvented now, you can get the vacuum harness, intake elbow, and fitting for the intake manifold. or get the harness, drill a hole in the hard rubber part of the elbow and tee into the fuel pressur regulator vacuum or AC vacuum.

Thanks guys for the info I went ahead and ordered the 6AL with the Harness and went with the stock Opti..(just in case) I already have the MSD coil so that wont change.
