I have the GSR crank already... would it be worth it to get an LS crank? Is the 1.3 mm longer stroke really noticeable? If I were to get the LS crank, what would I have to do to it to make it handle 9000 revs? just balance it to that RPM? (I know about the rods, bolts, and valvetrain having to be able to handle the revs.... I'm just interested in what I have to do to the LS crank to make it smooth at those rpms)

 

sorry... 1.8 mm longer stroke

 

Get the crank balanced, and continue to use the GSR block brace. Remember to use LS rods, or aftermarket rods that are the correct length. Also, use upgraded rod bolts.

You should notice the car pulling a little harder...I think its a great upgrade.

 

yep, ls crank is a very worthy upgrade

 

watch out for the oil squirters. i had to remove mine.
