440 ID help

[moparman440]

I need some help with figuring out what motor I have. I just bought a 440 that was supposed to be out of a 75 motorhome. The casting date is 3-24-76 and the casting number is 4006630-440-9. Also the ID pad reads 6T 440 E and below that there is 6-23-2. Mostly I am concerned with the compression ratio of the motor because I have heard that these motors had very low compression? It think it has the small plug heads with the spark plug coolant passages. Can any other info be had from these numbers? Eventually it is going in my 73 Scamp.

it's a '76 engine, more than likely used in a 77 model year truck. Yes on very low static ratio... If it were me, I'd lose the heads...
