I picked up an 5.0 motor and have been trying to figure out if it is H/O or not. Firing order cannot be made out in the engines current location, it needs cleaned well. I removed the valve cover and am reading a casting number 6E15...any help greatly appreciated. Have pictures if necessary.

look on the right side of the block, near where the starter would be. There should be a casting number there. also, the motor shouldnt have the firing order cast onto it anywhere... so stop looking.

what you can do however is... turn the crank over so that the intake valve on cyl#1 starts going down. now observe the intake valve on cyl 3 and 5... see which one moves first. If 3 moves first, its an HO... if 5 moves first, its NOT HO

Motor does not turn, sat for four years outside. I wish that it did. Was a crate motor placed in car, less than 1000 miles and car got tboned(totalled), motor got stored outside and some rain got inside. Swears he ordered it as H.O. but who effin' knows. He was going to take it to the scrap yard if I didn't take it...so I loaded it and took it. If I am reading it correctly: Engine casting reads 87 truck engine, June of 1996, out of CA. E7TE 6F19. But those numbers don't bring me closer to understanding if it is H/O or not. People have said it will say H/O on intake, but it's in cramped area right this second. Hoping for H/O, I hear the non H/O is a nasty P.O.S...
