Inliners International Forums General Discussion Engines 228 to 230 or 250 swap

I am about 2 hours west of Fort Worth. There is lots of large farm trucks around my area, but I am trying to do this on a small budget. Why does the price go up when you speak the work GMC. Either they dont know what they have or they want an arm and a leg for these parts. I will just take the free 250 and trans and do some fab. work and make it fit. The 250's seem to have lots of after market parts. I will make the 250 work for now and I will keep my eyes open for a 302.
