4.100 you dont even want to get into all of the PITAs that it causes Go 4" if you stroke it.

 

a 408 would require a 6.125" rod and a 418 will require even more expensive custom pistons to clear the extra .100" of stroke then you get to still clearance the pistons and counterwieghts and every damn thing else

 

im seriously thinkin of getting a loan to build this up..if i go 408 which rod do i use then??

 

6.125 same rod whether 408 or 418 the 418 requires even more extra special piston measurement BS. Get a full rotating assembly its the easiest way and you know you wont have clearance issues.

 

ls2's have a floating pin..do the lq9's have a floating pin?

 

yup..

 

alrighty thanks alot..sorry im out a questions for now..

 

use the 317s and mill them!!! or find a set of 243s i wouldnt waste my time on them. sicne the 317s flow alot more

 

How much do yo mill a 1 point drop and what pushrods do you do.(length) i, going with a 02 ls6 cam and 317 heads milled?

 

All you have to do is clearance the pistons just under the pin to clear for the counterweights. I've done a bunch of these, it just takes time. Who built your 4.100 motor?
