Motorhome engine 440

Like Thunder, I've built a few of these. I dont recall seeing any odd water pump setups, but I wouldnt question that there are some strange ones I've never seen. Depending on the year, it may be a 413. They were used in MHs to '72 or '73, and look identical. Check the block for the size in the casting. The lower end will have a forged crank regardless of year, many have the larger balancer the 6bbl engines used, because they also used the 6bbl type rod in them. (A thin balancer means LY rods in it) The heads have the same valve sizes (2.08/1.74), but the castings are different, having more water passages around the chamber and spark plug area. The exh valves are sodium filled (you can shake them and hear the liquid in there...lol) to help deal with exh temps. The sodium valves are heavier. They are a good starting point, but I generally dont use the heads, and earlier cars need the earlier water pump housing anyway (inlet ont he driver's side, vs pass side of later(post 71) big blocks. As far as the trans, I havent seen any from a big mh that didnt have the parking brake assembly on the trans. The mainshaft, and tail housing needs to be replaced to use this in any other application, std car or truck. The innards are all good tho. Hemi style 5-disc clutch retainer, the 4.2 kickdown lever, and 4 pinion planetaries should all be in there. (never say "always" with mopar...lol) There were also MHs with Gear Vendors O/D units on them installed by the RV places. I've only seen pics of that, but it's true..(that would be a nice score!) All in all, good stuff, but you'll need to buy more stuff to make them work. I wouldnt pay $700 for them. I'd go closer to $3-400, less if you cant hear it run.
