Newb question again, but would my crank be just as durable pinned and balanced by Darkhorse vs. having to buy a new one? Durable in a sense that the metal makeup of a stock stroker crank like the ones in the '07's are compatible with the big name brands like Jims et al?

That would be a question best posed to John @ DarkHorse. I know he can set your crank up "just right" for the 113" build, but I do not believe he can for the 120 ~ at least not economically. Dalton can answer that one ~ he had originally looked at sending his stock unit in for re-work and ended up going with the Jim's instead. I went with the Jim's initially, because my 05 crank is 4" stroke.
You have to change the stroke to get to the big displacement motors so you will need a crank any way .
Thanks Josh, Carl, and Phil as well as others...........I failed to realize the stock stroke on an '07 is 4 3/8" vs. what is needed on the 120" that being 4 5/8".[&:]
After what I just found out...............if I don't do the build I'll be spending my money on an extended warranty.[&:][sm=scared09.gif][&:][sm=scared09.gif][&:][sm=scared09.gif][&:][sm=scared09.gif]x10[sm=icon_rofl.gif]
Phil M is correct. No engine should blow up. With the exception of part failures. If the proper combination, clearences/tolerences are built into it, the reliability will be no less than stock. Engine failures happen from builders / owners pushing these measures to increase compression or reduce friction, drag to a point that clearences are overlooked or not capable of being achieved. the power will be there, but longevity is gone. A reputable builder with attention to details and conservative measures win out every time. I have a 120" engine with 131 foot pound and 128 horse that has 15,000 miles on it and has only had regular maintenace. Fluid changes and 1 plug change. I have had no failures or even (knock on wood) a leak since my guy assembled. I know that displacement of engine is capable of more, but how much do you like working on it?
Let me say that I thank all that replied thus far. I wanted to say this to you guys as I have read and appreciate ALL responses. This is exactly why I threw this question out there, for feedback from the experienced.
Now, can I borrow $6 grand? How much are kidneys going for these days?
