And last half as long, your smaller engines have only so many horsepower hours per displacement, and by todays standards, the steel used in these engines, well wasn't as crappy and well just higher quality as cast castings, most of steel we get now to build comes from china, and other foreign countries where the impurites are higher, if this guy were to ever rebuild it, it would be well worth the money to try and locate surplus cat parts v.s now adays off the shelf junk.
@nokiaicon I am working on a 3412 out of a D10 where the #3 cylinder dropped 3 valves killed a total of 4 pistons and connecting rods cracked the crank and many other parts not to mention sending metal all through the engine we are estimating between 65 and 70 thousand hope that gives you an idea

doesnt sound like a 3412 under a rev. must be a LOW hp build.....an 860 hp twin turbo sounds like a locomotive when revved under a load.

@SuperJuggalo5150 most likely a 5X4 combo or an 15spd with input shaft mods and a serious oil cooler..

Impressive! I've seen lot's of 3408's in trucks but this is the first 3412 I have seen. I'm curious to know what transmission can handle the torque?
