    I have a 2001 tundra with 4.7 blown engine. Found wrecked 2002 tundra with 3.6 v6. Trying to install 3.6 into 2001 but motor mounts on frame don't match. Anybody know where I can get swap engine mounts to match 3.6 to 4.7?

    Toyota use different mounts than the 4.7 vs 3.4 if my memory is right.

    mounts can be had junk yard or dealer or parts store.

    The mounts welded to the frame are different so I need some adapters to mate the V6 to the frame either the V8 mounts.

    Honestly you might have to fab something up to do it. Conversion in our trucks are rare anymore unless you go pre 1995.

    Why don't you save the headache and pita and just drop other 4.7 in.

    I think you may be right. I could cut the V8 mounts off and weld the V6 mounts in place, but I am leaning toward rebuilding the 4.7 or finding a used one. I think the trannys are the same for the 3.4 and 4.7 so hopefully I could use the 3.4 tranny I have now with only 150K miles on it.

    If the engine is out and on the stand I would rebuild the 4.7. long as the block is good. Off the heads to a machine shop for leak down test..

    What was the failure of the engine to begin with?

    Timing belt broke. Since it is an interference engine I will have to pull the heads to see how much damage was done. Engine has 270K on it. Found a used 4.7 with 109K for $1100 so I may go with that.

    Ouch.. bend valves I bet but sometimes you get lucky at times I would check it.

    1100 is not bad I would rebuild the front end, seals, water pump and all timing components. That way you saved a headache down the line.
