spun main bearing questions

[mopar_buddie]

so i found a 440 for sale on craigslist the seller says that it has a Bad main bearing i asume spun or seized he says the block is in good order so i would assume that it hasnt thrown a rod is this as fixable as replacing the crank or will this require more extensive work ive taken apart SB's in the past this will be my first BB if i decide to purchase the only reason im considering this is the price is good and ive lined up a junkyard crank for next to nothing anybody dealt with this in the past any advice would be helpfull

It,s not a big deal..Especially since you have done up small blocks in the past..If the price is right then go for it!!!

X3, if the main spun enough, it's 'clearanced' the block such that a new insert won't have enough 'crush' to hold it in place. Chances are it will probably spin also.
