Default ls1 346 vs 383
What would be the benefit of going 383 stroker other than forged internals?

more torque and if the same cam, heads, intake are used it will likely peak slightly sooner

Bump the compression while you are at it too

When I switched my HCI from my 5.7 to the 6.0 it was significantly faster

The bump in low end torque is the biggest improvement. It definitely makes the car get out of corners and start moving quicker. You would also see some power gains as well. I made just over 500 rwhp with my 383 and around 465ish rwtq I believe.
