Quick update.
I found out that the 270 is not stuck,it spins freely.
I also found the correct carburetor,Im slowly buying parts.
Im still missing the starter and I think It will be ready to start it.
Im just tinkering with this truck since I have a major project going on.
In the meanwhile I found a 302 gmc and a 270 gmc with the "H" head.
I dont have a project to stick the 302 into but I know it's out there.
well Thanks I will update as I go.


old guys and their old trucks rule!
