i have this rebuillt longblock i recently purchased (as well as some other goodies) from an old guy that used to have a turbocharged cvcc powered sandrail.. he had a few spare parts from his sandrail laying around his garage and offered me a great deal if i bought everything, and i did. he didnt have any knowledge what so ever about the engine other than he thought it was a "78 and its prob built for turbo. as he told me he was not mechanically inclined at all and said "i would only check the oil, put gas, and step on the gas pedal".."my builder would tell me what to buy and i'd buy it". i guess the sandrail as well as this longblock were built years ago. ive tried looking up info on "ED" cvcc series engines and cant find rock solid info to id its exact origin. HELP!!!
