    400 HP Tri Power 427? I thought the Tri Power 427 was 435 HP?

    425 hp was the single 4 barrel, and 435 was the tri power. Here's the scoop:

    "Early 427
    Chevy's first 427 generated 430 horsepower, but it often was tuned to produce 500 horsepower. Chevrolet sold it in 1963 as an option. The 427 went on hiatus until Chevy developed two other versions in 1966. One was the low-compression (10.25:1 compression ratio) four-barrel carburetor generating 390 horsepower and 470 pound-feet of torque. The other featured a four-barrel carburetor and a 11:1 compression ratio that produced 425 horsepower and 460 pound-feet of torque. All 427s featured a 4.25-inch cylinder bore and 3.76-inch stroke.

    Late 1960s
    By 1967, Chevrolet offered horsepower ratings of 385 and 400 on two 427s, with the torque rating for both at 460 pound-feet. The 425-horsepower 427 remained untouched. However, Chevrolet introduced its L71 427 with three two-barrel carburetors to generate 435 horsepower and 460 pound-feet of torque."

    That "early 427" mentioned in 1963 was the "Mystery Engine" and not even the same engine that debuted in Corvettes in 1966.

    Vall ..I wish I would have clipped a pic...the chrome tri power air cleaner still had the original 427 400hp sticker on it was worn but was still very clear to read...block code as well as the the cast numbers were correct...owner said he has had it since it was pulled from the car he owned and wrecked...there has to be a reason it sold so fast...he had good pics of it and looked untouched... from corvette web site..... Choices in 427 big-blocks were expanded in 1967, with three new Tri-power engines

    I wonder what was different between a 435 HP Tri power and a 400 HP Tri power 427? Different cam, lower compression, heads, or???

    I was wondering the same thing about what was changed also...in the article it listed the tri power as an option for the 400 and 425 horse versions...I am also wondering if maybe it was a service block or warranty blocked engine he was selling...I am disappointed that I did not get it...even of it meant I had to buy a car to put it in...I know makes no since but I have always wanted another 427...i had one of these https://www.ebay.com/itm/1966-Chevro...IAAOSwENVeOr5H
