Same hereI will remind you that I paid $200 for the entire long block.
I think I'd be building a very different kind of motor before I dumped $450 into just the crankshaft.

Dang you and all your 6.2 talk. This came up and I want it for some dumb reason

Though figuring it out is a big part of the fun, you could drop that right in if it's in decent shape.
Man, that looks so much easier than my "one piece at a time" method.Though figuring it out is a big part of the fun, you could drop that right in if it's in decent shape.
I have a use for that factory-style cruise control module. Hint, hint.![]()


$6.00 for the cruise stuff and I’ll keep the engine sounds like a fair deal![]()
The problem is I don’t have a truck I want to stick it in! Could put it in the 79 crew cab with an NV4500 and one of my ford 60’s![]()

It's kind of weird to look back on the string of 6.x engines. It has become boringly familiar now that I have most of the bolt locations and sizes memorized. Throwing a Banks kit & NV4500 into a '79 now sounds like a cake walk.
Ooh...I just remembered we swapped out the engine in the '93. So I guess I've worked on 6 of these engines, not 5.![]()
It’s not that I can’t do it, I just want to use an engine with more power in that truck. Although I may just end up tossing a 6.0 in it in the end who knows

Peninsular?I spent a 1000 on a forged crank that's currently sitting unused. I'll reuse it one day.

Scat quoted me $3200 for a billet one. Seems reasonable.

If a forged crank will prevent you from buying 1-2 more used engines I think it was worth it.
Considering each used engine you get into has the same probably for failure it's money well spent.
Nope they aren't equal. You got one that was turned and one that didn't. I'd be looking for marks that it had been turned.David's answer explains the failure mode and lines up with what I've read elsewhere. This wasn't a stock setup, and that may have played a large part in the failure. No practical way for me to test the surface hardness of that crankshaft given my tool set, but I wouldn't assume the two crankshafts are equal.
