It's pretty obvious you haven't done up pipes, down pipes, manifolds, head gaskets or a litany of other regular fixes to obs style truck with a 7.3l engine. The oil pan is a 2 hour job, tops. I've forgotten how many I did at my uncles shop. Doesn't matter if it's an obs or the newer style. Pop the mount bolts, jack the front of the engine up and have at it. Obs hold their value for a bunch of made up bs reasons. Just like the dreamed up 97 trucks are somehow better then the older or newer trucks. I got news for you they arnt. The updates were done for the 96 model year and carried over into 97. Didn't make any more or less power and weren't any better or worse then the 94/95 engines. The early 99's out ran them, and wasn't till ford pooched them out in late 01 for the 02 model year that there were any internal differences in a 7.3l engine.
Stop cocking off about forged rods, they started using them in 2002 model year. The sintered rods can take 450hp before you have to worry about them, and you'll split the stock block between the cam tunnel and crank mains around that hp level anyway. Literally been there done that. We stopped trying to crank big power out of them because they cost too much and broke too often. Heck I got 3 of them sitting in my driveway right now and another stashed at my brother's house. Only one still has a 7.3l in it.
Pulling the cab takes a couple hours, pick it up with the lift and everything is easily accessible. They were literally made to lift off with ease. Takes a few times to get it down, but once you do it, you'll never go back to screwing around like a cave man.
Why do you assume how many miles I pit on my vehicle has anything to do with my job? It doesn't BTW, just the amount of driving I do. Everything is close, but far enough away it's at least an hour round trip worth of driving. Just yesterday, I had to drop something off at my parents house, turn around and run into town to pick somethings up, back home and then to work. Just shy of 200 miles before I got to work. I'd have to check to be sure, but I'm pretty sure I'll be over 300 miles til I get home.
Then why is it so important to go 400-500 miles on an eight minute charge? Sounds like you just want to justify not wanting an EV.
