Anybody ever put stock tbi (manifold included) off 350 on a 70's model block? I read somwhere that the center bolt holes need to be machined to fit old style heads. One of you big muther truckers know about doing this. I bought a 88 sub for 150 bucs and grabbed some fenders, front doors, tbi (computer, harness, sensors, manifold,etc.) and then sold it for 100 bucs. I reeeeeeeely wonna put it on the jimmy, but need more info. help.
