I have a 1966 GM Buffalo stuck in Vegas with a bad engine. I need an engine and a good mechanic. I believe it is a 8V-71
Why not repair what you have ?.lol finding a left handed engine is getting tough for a good one
You should call Complete Coach Works in Riverside, CA. They will have them or maybe a 6V71 that you can slide in there. They had a few last I knew. Also G&R Coach and Bus Repair in Vegas may be able to put them in for you. 702.736.0757 Good Luck.
guy in OK had a buffalo wanted 2500$ for the shebang with 360 gallons of diesel, ran! Check the fishbowl page on facebook.
