74 Winnebago blown engine - advice?

[kage]

!! Wow!! A very generous offer (this guy lives like almost 700 mile away!). I will totally take you up on that if you are serious. This should probably go over to PM.

 OK, I'm back. First price I got for rebuilt turned out to be bogus, other rebuilts turn out to be rather pricey. May have found a running donor for $500 with trans. What to look for?  Hear it run, look at the rocker arms, watch the exhaust pipes when first (cold) started to see if smoke comes out,  check the radiator for clean looking anti freeze, check the engine oil before start up for burny or gassy smell, and watch out if it looks like a milkshake.  I don't think the vehicle sounds safe to drive.  What else should I look for?  Maybe hire a mobile mechanic for an hour to evaluate?

I seem to remember a thread on here somewhere where a member pulled his old engine and swapped it or repaired it out of body. Looked like it was actually somewhat easy..

[kage]

Not replaced yet,  wiener dog heh heh. Anyway.
Going to look at replacement engine tomorrow.  Aside from earlier questions on what to look for in used engine, is there any easy way to tell a 440-3 from a regular 440?

[pvoth1111]

Why not a modern engine/trans from a salvage yard near you.....

Mark, aside from a descriptive difference, I seem to recall somewhere on here that the engine is actually stamped with a code that says it's a 440-3 as opposed to a 440-1.

[kage]

It seems like the casting number on this one is 440-10. Some other reading I've done suggests that the -dash number after 440 is the number of the mold.  Each time they swapped out a worn out mold they added a number for the new one.  The interior information on the heads and cooling ports is good, but I'm looking for something exterior and obvious to a not very experienced would-be mechanic (me).  I've also heard about the 'peanut' spark plugs. What makes them peanutty? (aside from the flavor I suppose) Is it something I could see easily?

[Elandan2]

Why yes.  440-3 heads use a tapered seat spark plug that have a 5/8" hex.  440-1 heads use a flat seat spark plug with a gasket and have a 13/16" hex.  Simple huh? Rick

440-3 ID Number: 5 t 440 T (located on font of tappet rail)

5 = Model Year
t = Built at Trenton plant
440 = Cubic Inch Displacement
T = Truck (Indicates it is a 440-3 block)

Complete 440-1 vs 440-3 Spark Plug info is in thread Mark pointed to.

Turned out to be a regular 440 not a 440-3.  Thanks guys, on with the search.
