    WTB: 5.3 LM7 Longblock

    I'm looking for a spare 5.3 to have on deck and just figured I would try here to see if anyone has one they want to part with. PM me if so. Thanks!

    I've got one in my garage... milled 853 heads on it, ARP head bolts, ARP crank bolt, 228/222 cam, installed but un-run pushrods and pac springs, lifters and oil pump are out of an LS1 with 70k.

    Block I believe is out of an 05 truck with 160k, Heads I was told were 12K off of a camaro, currently dressed as a cable throttle truck engine.

    Whats the compression ratio of that engine and how much are you looking for? I know a guy who may be interested.

    It should be right around stock compression after milling.

    I'd take a grand for the complete motor, if you want to start excluding parts we can knock it down from there.
