Over to the new style, all were the same in the engines 05 and up.. But did they also swap to a new style crank in 05 or continue to use the same as pre 05's..??? I am starting a build on a forged 370 and picked up a 02-04 lq motor with 35k on it.. I plan to make about 650 plus hp with it, want to be sure on cranks becuase I am going to use the stock one.. Thank you

 

I think its only the 05+ LQ9 motors, and they started using LS2 style rods.

 

Yes I know that, but did they change to a new style crank as well?? Thats what I want to know..

 

Idk about that, but why don't you just get a complete rotating assembly from and 05+ motor and not worry about it?

 

no different crank that I know of.

 

Cause I already have a complete 03-04 motor sitting here.. I am selling the rods and pistons, poss the heads.. To do a forged rod, piston set up. I just want to keep the block and crank if it(crank) is the same as a 05 and after, as they went to a beefier internal set up as far as rods then the pre 05's..

 

do a 408!

 

ive never seen it mentioned where the crank was changed.

 

It was the LQ4 as well. Cranks stayed the same.

 

Negative.. 370 will be plenty
