Mopar 300hp/360 crate motor

Ok here's the deal. I ran across a 360 for sale. The guy says its an early 90's LA 300hp 360 crate motor. He bought it new and sais it does still have the tags on the block showing the information from chrysler showing what it is. He says it has 308 heads, all forged internals, and hydraulic roller cam. Its not supposed to have any more than maybe 10,000 miles on it. I can't find any info on the early la crate motors. I would like some info, because I'm thinking about buying it, sticking some better heads, larger roller cam, and better intake on it. I can buy the motor complete with pulleys, brackets, M1 dual plane, 727 with a 3000 stall for 500.00.
