will a 350 crank fit in a 305 thanks

 

Fit? Yes. Balance? Not easily. Why would you want to?

 

beacuse i spun a bearing in mine and the crank is really bad i was just woundering a buddy of mine has one and instead of buying one i figured i could use his 350 crank.

 

Just have yours turned. You'll probably need the block align honed too.

 

im preaty sure its to bad to be turned i measured it the good journels were around 2.100 the bad one was at 2.055 is that real bad or can i save it.

 

It can be ground .010" undersize, or more. Why did it spin?

 

i really dont know the night befor the engine overheated and shut off wouldent start till the next morning then it had the knock there was no water in the oil headgaskets were fine.
but a couple months ago i had jacked the car up on the crossmember and it slipped onto the the center steering bar and hit the oil pan and made a big dent and when i took the oil pan off i could see were it was rubbing so i guess some little peacies of metel got up in there. so can i reground it how
far can it go.

 

Grinding it .010 under isn't a problem, you can go more than that if you need to, but some people don't like to. Bearings don't just spin on their own, you'll need to figure out what happened and make sure it doesn't happen again.

 

I've got a clean .010-under 305 crank, one-piece rear main, sitting in the garage. Still in the shortblock, the bearings look great. I'd let it go for the cost of shipping.
