No. TPI is tune port injection. TBI is throttle body injection. For the most part GM quit using carburetors in 1986 and switched to TBI. EDIT: 87 being the first year for TBI
You should be able to find a truck for that price that you can just turn the key and drive home with. For as long as it sat every seal, hose, and gasket will need to be replaced, fuel drained, carb rebuilt, etc. If you have the time and money to have a project truck you would get a lot more out of it by starting the project yourself, instead of picking up where somebody else left off.
