Sep 7, 2004 · In terms of FB385 vs. 383, a 383 will make a little more power (20 to 30 HP) and they have a flatter torque curve. But it's harder to make that power because the bore/stroke relationship is more "truck-like." If you think about a pro-stock engine, they are large bore short stroke and so they have very good cylinder fill characteristics. Re: SBC 383 vs. SBC 400 (Jenny) I'd probably go for the 383 unless I already had access to a good 400 block. 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.Re: SBC 383 vs. SBC 400 (Jenny) I'd probably go for the 383 unless I already had access to a good 400 block.
