Like Rob, I went back to a good old points distributor when the HEI died in our L78 Chevelle. With a good advance curve and a good set of Accel points (not the race units)the car starts and runs fine.

Hey Keith...if I'm not mistaken, it was our very own Casey Marks that did a dyno showdown with a Pertronix unit and a regular points setup, and the Pertronix unit came in 2nd in the HP department...:

Mike (DaJudge) how easy is this kit to install...Andy M...more about that rev limiter unit too...

Hi Bob very easy to install can be done with distributor in the car but highly recommend installing with the distributor out. It will take about 45 minutes to install and that includes resetting the timing etc. I got interested in this unit because of the single wire design and a dyno test that High Performance Pontiac ran between a regular points set up and M&H's unit using the same distributor housing. The M&H unit came out on top with a 2-5 hp gain. I felt that even if it a wash in the HP area that not having to worry about wearing out the distributor cam lobes on an expensive and rare distributor was important to me. Points also have declining efficiency at higher rpms which has a serious effect on your spark voltage and results in poor high-speed performance, incomplete combustion and other drivability problems.

Here is a link for the info on the Crane unit:

The rev limiter is in 500rpm increments, adjusted with a screwdriver.

The main reason I chose this unit was I didn't like the idea of missing a shift and sending my revs into a low earth orbit.

Andy,

I'm with you! I like this rev limiter concept....

Andy,
Do you need to replace the resistor wire with the Crane kit? The Mallory kit works with the factory resistor wire.

I was advised to replace the points and the coil at the same time, and all of the wires were included.
I didn't do the exchange, since I had it done when the engine was rebuilt.
