I will be installing a granny 4 speed (SM465) and NP205 transfer case in my truck once I get back from tech school. I will also be removing the engine at the same time. I have found and old 366 chevrolet Tall Deck engine from a bus at a local salvage yard. I can get it for about $200.00. I am trying to build a decent truck for towing and pulling heavy loads. Would this engine be a good choice? 396's, 402's, 427's, and 454's are getting hard to find around here, otherwise I would use one of them.
