Author Topic:   Best Ignition System for the Money
posted December 22, 2003 09:22 PM
I searched the forum and I can't really believe there wasn't that much info. I know you can spend big bucks on an ignition system, but what's the best for the money? We're talking sbc running vortec's around 13:1. High performance HEI? With MSD box?

Don't want to spend $500 here, just want a good system for the bucks I'm going to spend. I actually want a whole new distribitor, too.

Almost forgot, running up to 7000RPM.

Get the MSD HEI Pro Billet Ignition- runs about 365, and you'll have no worries all year. we toasted many box ignitions this year and went to this, motor keeps the power...
if your looking for cheaper, get a good HEI out of a junkyard and completely re-build it with the Davis Unified Ignition Kit, its like 89 bux.. lock out the vaccum advance... its another cheap alternative, and you wont have problems with it either... just depends on rules and so forth

Im going with DUI on my streetstock this season.Its suppose to be as good if not better than msd.No box to worry about either.

A mag would be even more simple, then you could eliminate alot of things as well.

dui is overpriced. i have both a dui and a 100$ brand new performance hei off ebay...both work perfect up to 7000 rom.

We have run the MSD 6AL for years with no problems at all. Complete ignition system consists of MSD box, MSD coil, MSD billet (no advance) distributor, and Moroso wires. Plan on changing coil this year but other than that everything else i plan on reusing.

I know that gets close if not over 500$ but has been well worth it.

I have to agree with stock car 5. I have a DUI and a stock (bone) can't tell you which is best! spin them around 6800

I personally tested 3 distributors in my car in a 30 minute period while hot lapping. I could tell zero diff on the watch or seat.
stock with mud from the junk yard.
with msd module
with dui module

I use to run remote coils etc with msd module but dont even know if thats worth it.

I have been told by lots of engine builders that msd multi sparks are good for some power, but I guess Ive just never needed more. And Ive sure seen a lot of guys changing them out and missing races because of them.

no matter what ignition I ever have ran Ive allways wired in a separate hei power supply and carried one as a spare, I finally just left the spare in.

On another note I worked at super shops years ago and we had a ignition tester you could hook all kinds of ignitions up to, and a stock hei with a remote standard blue streak coil(stock round black one $20.00), was the best spark thrower,the coil wasnt new either it was out of a car in my yard, and very old. it could go almost 3 inches. while accell super coils were the worst, remote, and in the cap.
I also tested some mallory boxes etc and none could throw the spark as far as a hei?

msd is a multi spark, meaning it throw multiple sparks over a longer period of time.

hei, mallory,crane, holley etc I think are all cd, capacative discharge, meaning they build up for a big spark.

only way I would use a msd box is if I could run a 2nd one in the car as a back up.

I use a mallory and it was worth it,it may not put out any more spark to the naked eye but it makes for alot smoother turning engine.I thought i had a bad balance job on my engine when it was actually the ignition breaking down,not saying all do it,just mine.

to add to the dui story...i would be more inpressed if it lasted for a long time but mine did not. i have added a new dynamod because the one failed after 1 year. i also had to replace the center shaft because the brazing broke where they mount the advance weight plate to the shaft.

maybe its just my bad luck but its something to think about. 350$ can buy alot of other parts!!
