I have recently detonated my engine and shattered the ls cylinder walls but i had polished crank and rotating assembly that is untouched i now have the oportunity to get a ITR block and i was wondering if there are any complications in putting these two together or will i need parts from a gsr . Thanks for your input it is greatly appreciated

 

You may have to bend the squirters out of the way-I run an LS crank in my GSR block, but I plug the squirters so it's a non-issue for me.

 

It`ll fit fine. if you don`t bend the squirters, and you take them out, be sure to plug them or I`m pretty sure you`ll have oil pressure issues.

 

ls crank=use ls rods. other than that, plug the squirters and your golden.
