Yeah, if the computer's gone, forget it. Finding the right one and making sure everything is hooked up properly- waste of time. Just find a non computer carb and distributor and if they need tweaking myself and others here would be glad to educate you. I got real lucky when I removed my '83 Bonnewagon's computer. Found the exact correct '80 Dual-Jet carb and HEI distributor for a 231 in a Pontiac locally in a junkyard. Worked great.
