....just use the manifolds off your 4.3L motor ... no? Ya gotta figure you don't need to sell the engine with the manifolds, as it's very probable you'll be selling the motor to another V8 equipped MB, so they'll have the manifolds their engine compartment's configuration needs already.Originally posted by knvs
I will need to replace the exhaust manifold and engine mounts according to him. New manifold is $400 and a used one is $100. Also he said new motor mounts are $150 each (ouch) but from reading your post it's better to have them done now then later.
BTW, read my "if your car does this, change the motor mounts" thread on this board. My car feels like it's show-room fresh with the new motor mounts. I had thought my suspension was shot, and was only proceeding with this swap because I knew I'd be re-vamping the suspension with the speedybenz kit. But it turns out, it wasn't that (still happly installing the speedybenz kit though)
Also, there were a few other things I got new; a lot of the ancillary components on the engine I got were shot so Jeff stripped down my 4.3L motor and put them on the 5.4L motor. However as my 4.3L motor had a little over 63K miles, he recommended some of the things be new. In additon to the mounts, they were belt tentioner, crank position sensor (tho that may have been because of the fire), and I believe the master pully (hamonic balancer). I believe your engine was out of a car with a rear hit, but if not and was from a front hit, I'd change every pully and also use your oil filter housing from the old motor. What I was surprised about was Jeff didn't recommend I change the water-pump. I guess they can go a =lot= longer.
