What Electronic Ignition setup for Chevy 235

What are my options for an electronic ignition conversion for my Chevrolet 235 engine? This is in a 1954 Chevy car with powerglide tranmission.

In the Speedway Motors catalog they have a Mallory distributor with electronic ignition for my engine. Is this the only option? Is this a good option? What ignition coil should I run with this setup?

I feel like I should probably change out the distributor since it is the original piece of hardware.

I was considering on leaving the factory distributor and dropping in one of those conversion modules from Accel or petronix or msd. This seems like a cheaper option but is this a good idea?

I've used the Pertronix several times, it's a great part . Used the Crane version (XRi) a couple time because it had a built-in screw adjustable rev limiter and had no problems, but with Crane out of business....

You couldn't give me a truck load of Mallory Uni-lites. What a overly sensitive to voltage POS.

I agree with Ericnova72. The Pertronix unit is simple and works. The Mallory piece just plain SUCKS!

pertonix all the way.. they have it for 6 or 12v for the 235, so whichever you have...

only way I would run the mallory is if it was converted to a dual point distributor, but then it makes no sense... also figure theres over a $200 diffrence between them and the pertonix

Pertronix it is!

Nuff, said. I had a flame thrower on my T-bird but it was installe when I bought it.

I'm not sure which product I am suppose to buy now. Should I just buy the ignitor and drop that into my factory distributor? I was thinking of replacing the entire distributor since it is so old.

What do you think?

Also, there is no spark advance for this engine correct?

Also what resistance coil should I get?

Has anyone ever had to open the distributor and clean the optical sensor? I am wondering if this would be a reason to purchase a similar item from another vendor such as msd or accel?

The Pertronix and the Crane are both magnetic trigger type. The Mallory Unilite is the only one I know of that is optical unless Accel still carries the one they made in the late 70's.

Okay thanks. Im gonna go with the Pertronix ignitor. They tech support guy is telling me I need a 3.0ohm coil because it is a 6 cylinder car. Does this sound right? I find it to be odd that the resistance has to do with the number of cyliders?

sounds like petronix is gettin all the praise here!!!!

and... i would have to agree, the easy install job works perfect!

ive used it on several 235's. and the only advance you have is vacuum.
