I found a crank on ebay and it has this casting # and gm part #

Is this the casting # i should be looking for to complete my swap? :12552216

this is supposedly the gm part # 12559354

i looked up this part# and i think it's an LS1 crank, but I've also read that the #216 casting # is the one i should be looking for because it's the 01+, short flange style

but what about the casting #? do LS1 cranks have the same # as some LQ4's

which casting # should i be hunting for?

does anyone ever use LS1 cranks in 6.0l?

sorry for all the ?s ive searched all over and haven't found any answers

from what I've heard, read, looked at the junk yards, all ls1 5.7s and truck 5.3 6.0 are the same.
Same size bearings, unless they've been turned.
Same stroke, all internally ballanced.

You cannot use a 4.8 pulley on the above. Again just from what I've read, and from talking to the junk yard dealers.

PM mater or chevracer83 and they can tell you

i saw where the difference between the LS1's and the 6.0's is that the LS1's are hollow and have extra oiling passages somewhere.

has anyone here actually used an LS1 crank in their 6.0 swap?

this is the 1st i've seen anywhere about having to use a different crank pulley.

I never did check the difference in size on the pulleys, I'll check from my old one and see if there's a difference.

There's a TON of people that have done 6.0 swaps on ls1tech, post up over there and ask, you might have a faster response.
