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.
Find a clean seasoned 6.0L long block, and part out what you don't need.What's the best way to acquire a iron block?
Are you guys buying a new block from summit?
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.I agree, if I end up doing another motor it will be a forged 416 or 418 with boost.
