Mike this is a good topic and you're likely to get a raft of opinions. I'll toss mine in for you. I'm using an imported HEI distributor originally made for the 230/250 and I think may also work in the 292. About a year ago I bought another and showed just how I converted it with images, etc. The HEI I'm using has been going fine...I bought it originally in 1997. Not certain where it was made, but it is a copy of GM stuff...coil in cap and uses all GM components in case you need to replace anything. I also for a while used one of the mini-HEI units Tom Langdon made but I went back to the one from 1997 after Tom's unit had a problem I didn't have time to chase. The HEI is my pick for certain. Starts easy, runs smooth and strong and doesn't require maintenance. Even the one made in China (which can easily be adapted to the 235).
Here are a couple of points I'll add:
1. set this up so the HEI is separated from your ignition switch using a Bosch-style relay...at least 40 amp. Please, please don't get the idea your ignition switch can handle the inrush current when you start the engine. I have an ignition switch here I burned up doing that. The inrush amperage can be in the range of 23 to nearly 30 amps...for a momentary period, yes I agree it is but electricity isn't a forgiving thing and it is absolute. I can gladly rig up an electric chair for anyone who thinks a momentary rush of current isn't harmful, but I doubt anyone would agree to test their theory.
2. make sure you have an adequate-sized wire connecting it...there is plenty about that here.
3. advance your ignition timing a bit more than stock. 10 degrees btdc seems to be a happy spot.
4. separate your plug wires so you won't get cross-firing.
There will be more. Hope it is helpful. Points are fine...I'm not saying they aren't but the high energy ignition is a step forward in the ignition evolution.
