Hi all, I am new to the site, glad to be here, and thanks to all in advance. My current project is a 1980 K20 with Quadrajet on top of 350. While I have built up various types of vehicles, I have never dealt with Injected motors. I am considering a crate 383, or 350 injected motor from GM. The hype states an easy swap to injected with computer and all. I do run my trucks in Baja, and hence get less than pristine gas down there. So, my question: Honestly, how far over my head can I get with upgrading to injected? Is the upgrade worth it as far as performance ect? Or would the roller cam 383 w/Quadrajet (old style) be a better choice in this older rig? And, I welcome all advice regarding crate motor vendors!
