High value stroker build, how to?

My ls2 is quickly approaching 160K miles.
It's time to start building a replacement motor for my rig.
I'm looking to do a high value stroker forged build.

Does anyone have a proven recipe they would like to share?

As Jake said you have to give more details on your goals and budget.

What does "high value" entail? You can throw high end parts at a block and have it get its shit tore open by a junkyard 4.8L all day.

Some more details are needed and some homework on reputable, proven builders.

I went forged 403 stroker back in December 2014. I spec'd and bought all my components from Matt -LT1Z- (internals, pistons, cam, gaskets, bolts - anything he sells). Shipped to my door for a great price. I took them to my engine builder and two weeks later I was stabbing my stroker back in my TBSS. I have a little over $3100 in these parts (remote oil filter kit not included - I already had that), plus another $2500 for AFR heads.

I got lucky and only cracked a single piston under @12 psi of boost so I re-used my stock LS2 block. Honed it out to 4.005 with new forged everything.

Any advantages to using an LS3 block?

Find a clean seasoned 6.0L long block, and part out what you don't need.

But, you may find yourself saddened by a boosted factory-stockish 4.8/5.3L when it comes to overall expense vs performance.

LS3 would be my choice

I agree, if I end up doing another motor it will be a forged 416 or 418 with boost.

The stock ls3 crank should be good for 800hp & up figures. No need for forged crank. The piston and rods are it. I think a crate LS3 would be perfectly fine. Not certain which specific LS3 engines are considered LSA series or have that DNA. Maybe Matt could speak up here on that.
