I'm thinking I could use a prom for a 81 stock with 4 speed. I have converted this from an automatic, and have been told that the Prom needs to be changed due to the tranny swap. I have a hypertec, but would rather have a stock if I can get one.
Reference ECM: does anyone know if I got a rebuilt one, would it include a new PROM?
As always, thanks in advance! Jim
