Similar HP, but the LS3 drives 1000x better. The 350 to get that HP was pretty radical with a high stall converter. The LS has a high stall converter too, but it has OD with a lockout. Engine wise, the LS3 is just like driving my pickup with a 6.2L in it. Night and day difference.

The 383 as must know is taking a 350 and putting a 400 crank. Both of the above replies are correct, since both the 350 and the 400 are on the same archetecture, once you take a 350 and put a 400 crank in it, it is just a bore difference form being a 400. There are difference in the blocks overall, so you can't just bore your 350 .120" over.

The 23 extra cubes of the 406 (a 400 block with a .030 overbore like the 383) should yield a nearly proportionate power increase but I don't think it would be that noticible a difference unless measured on a dyno or at the strip.
