81 301 computer necessary for swap?
« on: January 01, 2020, 08:51:11 PM »
I have an 81 Formula with the 301 non-turbo. I know nothing about the 301's. Engine is locked up and am going to do an LS swap. I know I don't need the computer from the 301 for the swap, but is it necessary for anything else...gauges, etc? Or can I just take it out?

No. The computer was only used to restrict or control the throttle/carb. It had nothing to do with how the gauges or other components operated. However, that being said don't throw it away as some people may be interested in it for their '81 Firebird restorations, as they all got chucked out when they were new.

All the 81's had computerized spark advance also, so that was pretty necessary back in the day.  But as far as the body of the car, it doesn't hook to a thing.  It reads speed off the speedometer, and you'll see that when you start peeling it out of there.
