406 sbc vs 383.

If you leave the cam the same, you will see very little gain in HP, but it will make peak TQ and HP sooner (about 200rpm).

I've decided to have a 383 built for my 68 vert. The builder has given me two options at the same price. Option #1. Dart Iron Eagles, 200cc runners, 72cc chambers, flat-top pistons. Option #2.

The 350s use a 3.48" stroke, the 383s use a 3.750" stroke.

I think it would be a lot more to build a 383 compared to a 396. At least were I'm at, there are the '66-'67 396 blocks everywhere and they all have steel cranks.
