    i have an 87 w/305 TBI swapping in a 350 w/ carb. will the TBI bolt up to the same intake as the carb. Or will i have swap intake manifolds and will the swap? And will the same TBI work on the 350 ?

    If I am not mistaken.....GM changed cylinder heads in 87. What year 350 are you putting in? The TBI will NOT bolt up directly to a carb manifold. Why not keep the TBI and put in the 350? It is a direct bolt in swap. I don't know for sure but I think you can use the 87 305 ECM for the new 350 TBI.
