Hey there are all kinds of manifolds for the small block 350. Just not to many dedicated to tbi!! You can pretty much put anything you want on as long as it matches your bolt pattern. I.E old style 12 bolt/ 90's and newer style 12bolt, slightly angled centre bolts and then the vortec 8 bolt style. After you pick a manifold just order a carb to tbi adapter from holley/transdapt/ or turbo city and you can bolt your tbi onto that manifold. It may take some minor mods but all easier stuff. Hope that this helps some.??
