I have marketed this system for 20 + years. Sold 100's. They worked quite well and thru the years I never had any comebacks. Mine used aluminum adapter plates on the front of the engine that included the motor mounts which placed the engine in the stock position. I also used a custom lower crank hub which enabled me to furnish stock short pump Chevy pulleys. Also came with an alternator mount or optional air/alt mount. In the beginning I furnished a rebuilt pump but later was able to supply a new pump. I did a few with the truck pump which raised the fan about 5 inches. I'm no longer doing the kit as the cost of producing the parts has risen to a level where I can't be competitive. I think there is still a picture or two of the unit on my website.
