I have a ls3 block std bore i was told by a machinist here i needed the following for my build. Eagle 4.10 crank, 6.125 eagle rods, and 4.070 forged pistons. Is this correct and a good combo??? Im looking at prc stg 2.5 6.0L heads milled to 69cc trying to get 600hp is this possible with this combo? Thanks

Again the 4.10 crank starts to really pull the piston out the bottom of the bore.....
As far as your goal as 600 horses.....
I would read this article.....

Also I've looked at prebuilt bottom ends but after research i dont car for aome of the parts used in them. I would rather spend the extra 500-1000 Bucks and know its solid i think

Just wanted to share this build here with you also.... it's a old thread but it still gets attention due to it being a absolute beast.
