Snowman? Are you also installing the tranny that came behind that 350 TBI engine? It would be either a 4L60E or a 4L80E (electrically shifted). If “yes” then your installation is feasible. If “no” then your installation becomes electronically much more complicated, if not impossible. Also, the Vehicle Anti Theft System (VATS) from that Suburban directly interfaces with the ECM, such that the computer won’t power your fuel pump circuit if it doesn’t get inputs from the VATS. There are guys out there in cyberspace that have the smarts to defeat missing inputs or outputs from things like the auto trans or the anti-theft system by reprogramming your computer: $$$$$. If you have an automotive background that includes working intimately with OBD-1, then you might have a chance of making your idea fly on that 3600. (Been there, done that, but wouldn’t do it again). If you’re just a weekend warrior, well, you might save yourself a lot of aggravation and do like bartomos suggested, and go w a carburetor and HEI.
Good luck.
