Hello, I have a question about doing an HEI conversion on my 1990 Suburban with a points system, YES a 1990 suburban with a Points ignition System. Is there a certain distributor I should buy? A Pre 1975 Truck? Car? Van? Does it really matter? I'm thinking it shouldn't matter but I've read about a power curve built into the weights & vacuum advance. My best guess would to buy a 1974 3/4 ton Suburban with HEI. Basically I need a new Distributor, Igntion Module, Coil, & wires right? Of course a little rewiring for a 12v source in Start & Run. I should be able to use the same Spark Plugs but maybe with a bigger gap? Any other suggestions are welcome! /forums/images/graemlins/thumb.gif Thanks a trillion in advance for all your advice!
