Victor, Super Victor...or just stick with my LD 340 maniflold

I'm not a fan of dual plane intakes on strokers in performance builds. If I were building one with low compression for a truck without much gear then yes.

For the op, I'd look for a Weiand X-Cellerator or something similar. At your weight and smallish cam IMHO a SV is too much intake. A Victor would be the biggest I would consider.
