As I said earlier, I have an offer for a 440/727 w/accs. for 5 bills and it's only clocked 20,000 miles. In the course of reading and searching for tidbits and things I would encounter, one of the first things that drew my attention was an article online by a well known monthly mag where they were talking benefits and drawbacks. The first I noticed was that most people thought the 440 was a thinwall block only good for twenty thousandths overbore, and the blocks were thin. It turns out that there was only a slight difference in different year modles, but that they were not wall thinness related, and all the motors were sufficietly thick of ALL the 440 variety. They noted some differences in the motorhome application motors which were tuned for torque of course. The rockwell metal hardness was the next issue that caught my attention. A test where a steel ball is pressed into the block metal and the indentation is measured and the psi to get the pressure to cause the metal to 'dent' basically. That was true that the nickle content was lessened in the late 70' or 80's (don't remember the year) but those were the real areas of distinction. Fatter rods, cast crank, rv lift cam, and probably minimal valve size. Even with these things in view, you could get 916 heads, h beam rods, some nice springs and valves and lumpy cam and build a king kong motor for the Ramcharger. OR, go completly stock.....ish and only fiddel with the carburation and distributor and have a superfine street driving, towing motor. The biggest no no to come across on a 440 for a donor, is one with the industrial mounting of accessories.
So you see....... decissions, decessions..... sould I or not? Well I only drive around 1 or 2 hundred miles a month max anyway.... so the gas thing isn't too hard to deal with, and I do have a boat I pull, a 17" bowrider in/out. so...? I believe I'm going to try to get this motor and trans, and with 20K, it ought to both be clean.... and also have gobs of usable shelf life left, like over 100+K more trouble free. Where only buying gas and insurance is involved, its not bad, considering those with big fuel costs, monthly payments and having to carry full coverage.......... mine's still way cheaper....and look at the 'Fun' factor.
Oh I uh forgot to add... this is a two wheel drive Ramcharger Prospector. I'll probably need an 8 3/4 rear soon, with tall gears, like 290's or something..
And a limited slip or posi..
And traction bars
And 10-12" meats
I''m sure theres another 'And' in there somewhere......hmmmm.. aw who am I kidding, it's only a big block motor home motor.
