I had a 267 4.4 liter in a 1981 Chevy Impala I bought for the motor and tranny for 75 bucks ( car was compleatly toatled but motor and tranny were fiine ), I wanted to use it for a repower on my '83 MB 240D and, I researched these engines. I researched that they cannot practicly be turned into a 350 ( if at all ). In stock form they make 115 HP. I junked the car soon after I gave up on the Chevy V8 to MB conversion, this was 1 of the main reasons I gave up, I will compleate that project in a year or so with a Ford 302 for a daily driver ( not worth much else with 252,000 miles on it ).
