There was a guy out on eBay that was selling an adapter plate that let you bolt up the 292/v8 pattern directly to a stock 50s bell housing.
I was thinking of doing that and getting the Buffalo Engineering bell housing with the welded on break and clutch pedal mount.
Anyhow I haven't gone that route yet as I still have a few 235s sitting around. That is a very simple swap and is enough power to be scary with original equipment in my 1940 trucks.
I would like to put a 292 in my 1 1/2 ton but I don't know how to stop it yet.
