Has anyone here used this product? Sounds very interesting. How does it compare to the GM HEI upgrade?

I bought one for my 67 race car ..

Only reason I did , was after 2 chrome box failures this season ..

And costing me late round wins


Their claim of 40 horse ..




But, it didn't make car misfire like the chrome box so ...

So, how well does the GM HEI work?

The HEI conversion is no better than an MP ignition box,UNLESS you upgrade to an aftermarket module like the Accel Mallory . HEI from the factory pulls dwell at high rpm.
The Accel doesn't,but current is still limited due to heat issues You can only put so much current through it before it overheats due to area available to displace heat. Thus the reason you need to properly mount them.

There was a comprehensive thread regarding this awhile back if you can retrieve it. If it ain't pulling out dwell like alot of ign boxes do that's OK but I look at it as just a pri current switch & prefer to go with a killer coil/less ballast or next step will be an E coil/no ballast. the 40 horse claim should be a tip off. The old saying about frauds/cons: "if it sounds too good to be true then it probably is" (not true)

So, using an aftermarket ignition module such as the Accel Mallory will be a better alternative if putting together the GM HEI conversion?

Ya you buy a $50 GM style HEI module instead of the $200 rev nader.

If I was stuck using an HEI module that would be the one to use. 50 bucks give or take and make a heat sink plate and wire it in. Not my ideal ignition but better than a parts store plug in replacement ICU .

Keith ..

I read thru the long post about it , were you did a lot of testing .


By reading that , I made my purchase

Now ..

Not trying to put words in your mouth ..

Has your opinion changed ??

Maybe I'm just reading it wrong , I can be confused easy ??

No change in my opinion,the Accel HEI outperforms parts store boxes,not the Rev N Nator
I have tested every plug in replacement I could get my hands on,its still the best. It runs with my dyno mounted MSD and the Accel digital300 I've run in my personal car for ten or so years.
The 40 horsepower gain subject has been beat to death,those gains are against a parts store box that pulled more dwell than the MP units.

I'm basically happy with it so far


Next year, in the spring when weather is nice

I'm going to buy another chrome box and do back to backs on it

maybe I'm crazy but, I think the chrome box outperforms it but they just don't live


Mine is mounted inside the car, properly

This is the car I just built for my wife to bracket race. So far I have seen just under a tenth gain with the Rev N Nator over the Chrome. But to be fair,the car only has a handful of passes so far and our tracks are closing for the winter.

I was not able to back to back the test

but, there was no gain , if anything slower

Hard to be honest cause we got a lot of wind late in the year ..

Motor sounds better and fires quicker with the chrome box ..




It doesn't come up on the chip as fast on the trans=-brake and my reaction times slowed after the change ..

Consistency of car wavered too..

could of been many things but ? doubt it

Jury is still out, not ready to say either way yet


Most likely I'll swap to a brand name ignition at some point


I am not impressed so far ...


The claims they make are silly

Yep,give it a chance. They offer a money back guarantee.
When I first took her Coronet out I had some detonation.
Pulled timing out and slowed down.
Took me a while to figure it out but it was the shift light. An MSD wouldn't let the light work,the Rev box had detonation but the Chrome didn't . Changed the shift light and now no detonation with the Rev box . Must have screwed with the signal from the pick up or something.

From the posts you have made

And I know you have many hours in testing it

Seems like many things are not compatible..


I made the swap, late in the season and I'm on the fence





My car was dead consistent previous ..


On fire up, motor barely spun over and fired before ..Now, it takes a couple cranks


and , it does not sound the same



it kicks butt down low, 60's good but lays downs on the 2-3 shift



MPH is is the same though


for lack of a better term, seems like it surges a little

Its just not the same car with it

I bought one in July at Carlisle and installed it after returning home. Ive noticed no difference really. I dont race however, so that might account for something. My RR runs the same. It always was easy to start and it still fires on 2 or 3 cranks.

Im not unhappy with it, as it seems to work fine as a ECU. Then again, im not sure it was worth the $200 either.

/i had one,i really liked it.did i get alot more hp? no.it did run better though.i could not get my tach with shift light to work with it.my tach would jump all over the place.so i rendered it usless in my application.went back to chrome box

I know Ive mentioned it before,but the perfect tune with any one ignition system wont be correct when you plug in a different one. But even perfectly tuned,most guys cant feel a ten hp difference . If you have a lean or rich condition and put a better ignition system on something that was marginal before it will change.
If you have an ignition that pulls dwell,tune around it,then change to a system with a better dwell curve you will need to change things. Its the same thing I see with guys going to an MSD and not seeing a difference. Or an out of the box carburetor. Things need to be tweaked to get the most out of them.
Everything I test gets run through the wringer. I keep coolant and oil temperature within a couple degrees use the same fuel,and test several times to make sure its not an anomaly .
I realize not many guys can do that,but I try my hardest to give guys good fact based information .

Wasn't there a Standard ign brand ECU like $40 , that performed better than the orange and was about the same or better than the chrome ?
