383B Stroker Build
I could be wrong but I think you may have missed on both points. 1st the small bore of the 383 (4.280") may interfere with larger 2.20 intake valve that's used on the Victor head. A 400 block would be a much better choice for this head, imo.
Second, I do not believe edelbrock makes a low deck "max wedge" intake. They do make a 440 one.
Oh, and most guys that have low deck motors generally would recommend a standard port. You can support well over 700-750hp and don't limit yourself on intake options. But hey it's not my cash.....
