Bought a 1990 5.7 liter motor, came off a Suburban. No fuel injection and no computer. To make it run, I installed a Q-jet carb and my old points-type distributor, with coil and resistor, and Jacobs Omnipack.

Everything ran well until this weekend when I killed the electrical sytem after leaving the ignition switch on for many hours.

The points, coil, resistor, and Jacobs Omnipak were all fried. Don't have the money to replace and duplicate my old set up.

Today I just installed new points, a cheap coil a 1.2 ohm resistor. It fired up but the timing is off. I can play with all the different combination until I find the right setting or run out of gas.

My big problem is I don't have a baseline to set up my tuning parameter.

Has anyone have any idea what I should start with? Points gap, timing position, dwell, carburator, etc?

Why don't you get an hei distributor? Only 1 wire . and an extremely reliable set-up. you can get them cheap from a junkyard probably less than $20. Best of all no points, or adjustments.

Start off by putting an HEI distributor in it.
