looks like one of the open class motors from the 80's or 90's. depending on the year and if it has been modified it should be a 510 inch with either 13 to 1 or 12 to 1 compression. most were lease motors. you bought it and went on the program and the rebuilds were a set price. should be good for around 7500 to 7800 sustained rpm but they dont make any power till around 4500 or so.
