I have a 76 280Z. Afew years ago it was vandalized and I needed a quick engine replacement. I installed a 79 ZX engine.(tremendous drop in performance - a mistake)I used the 76 injectors & they function. However,I notice the injectors for 79 & 76 are not the same. Whats the difference? Would changing the injectors to the 79 type improve performance,mileage etc ? I have the 79 injectors that originally came with the ZX engine, so it doesen't mean buying replacements. Eventually I'd like to reinstall the old 76 rebuilt & improved, but until then the 79zx is acceptable and dependable. I'd like some feedback, thanks.
