1968 GMC 351E v6 vacuum lines - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 1968 Gmc c25 that has a 351E V6 it wont idle. I think it is a vacuum line problem. I need to get another carb but they are hard to find. I want to put a eldbrock or holley on it. Would I be able to run a 4 barrel on that engine? Does anyone have any suggestions? I want to keep the original engine in it.

You could probably run a 500cfm on it. Im not sure what the manifold looks like or if there is an adapter for that.

Thanks I was just wondering about the carb, They do make a adapter for the gmc v6's they sell them at napa here in town.

I tried to join the 6066 club and for some reason it won't let me, keeps saying that my introduction is to long.
I got the request to join sent in finally. thanks.
