Identify this motor by the heads?

[jb1dsl]

I got a roller motor today and the guy said it came out of a truck. I looked for numbers on the block but did not see them. Can you I dentify the year ands specs of the motor by the heads? The heads have never been off of the motor. the intake looks like one off a 94-95 mustang but it is out of a truck. the heads have 4b7 and 4b11 and a large t cast in them under the valve cover. im thinking it is a 94 maybe, let me know the specs( hp, c.r., type of pistons, etc). I will be breaking it down and rebuilding it with more performance parts. He gave me the stock crank, rods and pistons out of his 94 gt block. what was the comp. ratio of these motors? Are the stock 94 gt pistons hypers? Is there somewhere specific to look for the casting numbers besides the starter area?

Thanks
Brad

do the heads look like gt40 heads it could possibly be from an explorer either a gt40 or gt40p casting??? if it is out of an explorer i belive the pistions are hypers... however if it is a 5.0HO mustang motor that was just in a truck then they would be forged.... however im just thinking out loud... wait for someone else with more knowledge to respond

i did not see the 3 or 4 lines on the end and they did not have a gt40 stop inside.

i found some numbers close to where the starter goes. it looks like 4a23 or 4a28.

looks like a 94-95 to me.

i was reading and found where H.O. motors had 19 lb injectors (orange) and non-H.O. had grey injectors (Gray). the motor I got has orange so I guess it is a H.O.
