85 carb coming out going in will be a 91 tbi 350 what will i need to keep my lockup with out messing with rewiring a buch of **** and another thing can i use an onblock fuel pump like pre 87

 

Your title and text don't jive. Are you removing a 305 and installing a 350? If that's the case, take the carb stuff off of the 305 and put it on the 350. Everything will function as before. However, some later EFI 350's don't have the mechanical pump area machined, so you would have to rig up an electric pump in one fashion or another.

Or, are you removing a carb'd 305 and installing a TBI 350? If that's the case, you won't be able to use a block-mounted mechanical pump.
