OK someone help me here. I have a '86 K5 with a 305 need new engine now. I have been told that a 350 would need new sheet metal (i.e timeing cover oil pan etc.) and that the exchange would be easier by just putting another 305 in the truck. ''Will a 350 exchange out??? I don't have vortex heads just run of the mill heads. Will the intake manifold off the 305 fit on the 350 and will the covers (valve, oil pan and etc. fit back on the 350 from the 305.? I'm trying to do this for a minimal $ I can get the engines at 1129$ with a 4 yr 100,000 mile warranty with gaskets and all. I need to order the engine today if anyone can answer me todya I'd appreciate it. Either here or by E-mail to <firstname.lastname@example.org> Red Springs, N.C.
