    What motor is this?

    So I picked up this motor for my dad from a guy who passed away's daughter. Basically she has no idea where it came from.

    It has 799 heads and that sensor that hangs by the crank. you can see it in the pic.
    It has a return style fuel rail, 78mm DBC TB, and an oil pan I have never seen.
    I also noticed that the valley tray had embossed lines all over it, is that a VVT or DOD thing?

    I was thinking a L33HO with the intake swapped.

    I think its the front sensor, thats the one that comes around the balancer?

    It has 5.3 stamped on it.

    I guess I'm looking for an F-body pan and oil pick up, Its going in an off road buggy.

    Front cam sensor is dead give away for Gen IV, but the intake is not. Maybe from an envoy or SSR. I don't know much about either of those.

    look at the color of the crank sensor, its located on the passenger side of the block above the starter. If it's grey or white it's a gen4 engine. Black sensors are gen3. If you don't have the sensor, look in the hole and if the reluctor wheel in there is two stacked plates it's gen3 and if it's one solid plate about 3/16" wide with evenly spaced notches it's a gen4.
