    Does anyone know the horsepower ratings on a 1977 440 HP motor? I'm guessing it probably came out of a cop car. This motor any good or is it just a basic 440 engine and nothing special. This is what's stamped on it.

    7T44 TE HP

    Thanks

    I had a similar engine a long time ago, and from what I (vaguely) remember, the cop motors were built similar to the old 375 HP Magnums but the compression was lower for emissions. I read somewhere that a pedestrian 440 had 8 something compression, but a cop motor was in the 7's!

    I tended to believe that claim because mine would run on any octane with no issues.

    As for special cop parts, most of what made it 'special' would be replaced anyway with a full rebuild.

        . The 75 was 260, 76 was 240,and the 77 was 195 HP. The 400 was only down to 190.
        The 440 was down to the last year(78) they ran terible, overheated, and smelled like rotten eggs all the time. I know because i had to work on them, and had friends that owned them.
        Now today with a fresh 69 383 or 440 HP in a Cordoba would make a really nice package.

            True, there are two 440 HP in 1977. one is lean burn, one is high altitude. one is 195, the other is 190.

                Cool. I saw one come up for $750 but it's pretty far away from me. Sounds like i might be better off with any run of the mill 440 especially an earlier year.

                    Good blocks. They have a better casting. Dick Landy's go to block was a late 70's for the thicker journals and higher nickel content

                      72 and earlier 440s had the better nickel content, but their isn't that much difference. The later 440s have thicker motor mount ears and reinforcements in several places. 440 source is a good resource for the different years. The hp typically had windage tray, double roller chain, better springs w dampers and the magnum cam. 77 era 360 e58 Police motors have better valves and higher nickel block, but I have never seen where a 440 had those features..and I have never seen a 77 440hp to really know how it's equipped. .http://www.440source.com/blockinfo.htm
