Need help!! 6.0 swap
If you swapped the heads from the LS1 to the 6.0 and reused the stock head bolts theres a problem right there. Stock bolts are torque to yield and are junk after used one time.
If you swapped in the whole 6.0, could be bent valves,rings, hard to say. We need more info about the motor than "it has no compression"
Did the crank sensor fix work ?
but then i though it could be the valves cos i was running it with out the cats just the stock exhaust manifold.
