Now for EFI I want simple for now , and with the modern conversion parts that are out my hp gains will be at most 10-15hp less. Also I want simplicity and not ecus and harnesses. This will not be a DD, but wil be a street rod kinda setup for the weekends, and is a project for me and my dad since he has never done this and I too, wee don't wanna fight about what goes in there. He just rebuilt gmc Sonoma and a gmc full size that both have all the ecu harness etc. I'm sure this will be a break from those trucks.now the benefits of carb and EFI and my main concer is getting this engine in and making the wheels go for now . I would like info though on how to do everything as I am learning an new to this, but want to so my research before I do my project, and order parts then test down the truck. @kewijay
