Drop-in ignition update?
I am not a speed-freak nor a street-racer and can't remember the last time I went faster than 60mph in my car. High-speed performance isn't an issue. I just want the car to purr...
That said, can someone recommend a drop-in ignition update for a stock '74 350 auto? I'm getting ready to tune-up the car and figured this would be a good time. I would like to replace the points with one of those "little-black-boxes" that fit under the original distributor cap. There are so many options, I have no idea whose hype to believe...so I will rely on yours!
Thanks in advance,

I tried a couple of the conversions and fried them both. I am back to my orginal points. I am using a curve from Lar's and a set of Mallory points. The car runs great and I do not have to worry about a failure in an electronic part.

In my humble opinion, stay away from the Pertronix Lobesensor. I had one and it was a real PITA. It took a 5 second delay at every start. After it started it worked faultlessly, even smoothed out my rough idle (which I later found out was caused by a wornout lower distributor bushing.)
The Ignitor II is supposed to be better, it requires the distributor to be pulled to install. With a high energy coil it will work as good as an HEI.

I put a Pertronix Ignitor in a 74 350. Ten minute installation time, and has given no problems in over 10,000 miles. Also improved the gas mileage (although the previous points might have been old.) It's a better install than Mallory's system, and the extra wire is easily hideable for a completely stock look.

Re: Drop-in ignition update? (74FLCONV)
I installed a Pertronix Ignitor in my 74 at least 3 years ago and I haven't had to touch it yet. Dollar for dollar it's one of the best, easiest, and economical mods I've made to my car. I agree that you should go with the original Ignitor and not the lobe sensing model. The one I have has a magnetic ring that fits under the rotor and a pickup that replaces the points. Put it in, connect the red wire to the plus side of the coil and the black wire to the minus side of the coil and you're done. Dwell and idle haven't changed since I installed it and it starts immediately every time.
