A good HEI with a blue standard ignition cap, and fresh coil/module will go 5000-5500 without too much trouble. Passed that in RPM you need a really GOOD HEI. I used to run a Mags R Us unit from NY I believe. It was less that $200 complete, and never ever failed me to 7400 where I quit twistin the Big Block.

Advantage to an HEI is it is all one unit, so if you are having ignition troubles swap the entire piece to make the feature and troubleshoot the problem later.

Any high energy ignition, HEI, MSD etc. requires you to stay on top of the plug wires, you buy $10 wires you get hundreds of dollars of misery. Higher voltage systems are more prone to failures with cheapie parts.

We use an MSD billet distributor and an MSD box with a ford coil in our mod these days, but theat takes 175 for the MSD box, another 175 for the distributor and the coil. ANd anyone that runs an MSD will tell you, you best have a spare box in the trailer especially if you ever wash the car.

Run a MSD pro-billet HEI ignition, you won't have to worry about that stupid box, coil or wiring problems etc., plus you can buy these from jegs for about 330.00 dollars, which that pretty cost effeicent for a racing ingnition thats ready to go right out of the box.

The Holley Annihilator ignition is a good
one.It has a built in rev limiter and the
spark looks like a welding ark.Be sure to
silacone the seems to prevent moisture.

Are the D.U.I. systems considered multiple spark? Does anybody know about how much they run for price.

One thing I read about MSD was that they are not multiple spark after 3500. From the readings in Circle Track a while back, they said their simply wasnt enough time for multiple sparks at that RPM. Just something I remember.

Hard to beat a HEI for simplicity. I believe you can buy a kit from Speedway to convert a junkyard piece into a racing one. Probably the cheapest way to go.

Myself, I use a complete MSD system. 6AL box, billet dist, blaster coil. No problems yet, altho I do have a spare 6T box...

And yes, this is a claimer class too.
