Hi, Mike. I've not heard of the Staghound power plant but when I was a teenager, a group of friends and I dropped a GMC 270 into my 1936 Chevy 2-door sedan. I removed the 270 from a rolled over 1951 Jimmy pickup truck which I bought at a salvage yard for thirty five dollars Nobody, and I mean nobody, could overtake me in a street race from a standing start until four city blocks later. That's when drivers in the V-8's took over.
Presently, my parts chaser is a 1957 GMC 100 with its original 270 inline six under the hood. It is such a torky and dependable engine, that I wouldn't replace it with a V-8, no matter what.
Thanks, Mike, for the memories.
