An aluminum LS2 block with a 4.00" stroke crank will net you 402ci at the standard bore. If you have the cylinders honed .005" with a torque plate you'll have a 403ci engine.
When people talk about a 408 it is usually the LQ9 iron block bored .030" with a 4.00" stroke crank.
(Either one of these two blocks will handle 800rwhp if assembled correctly with the right parts. It all depends if if you want the iron block for a little more strength, or the LS2 block to save some weight.)
An LS1 or LS6 block with the same 4.00" stroke crank will get you somewhere around 382 or 383ci.
LS1=5.7L 3.898" bore (aluminum)
LS6= 5.7L 3.898" bore (aluminum)
LS2=6.0L 4.000" bore (aluminum)
LQ9=6.0L 4.000" bore (iron)

can i run 15psi safely on a ls2 block if i forge it. i want 800rwhp on a dd but dont know squat about the positives and negatives of iron truck blocks. i really wanted 2 have a ls2 block because of how great people say they are 4 high hp.
