Inline six carbs - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Maybe this should go in the "Engine" section, but it's related to the "Post Your Straight Six Pictures" thread, and I didn't want to hijack that thread with a question.
Having said all that, I noticed a lot of 4BBL carbs on the engines. Some of them had the primary's facing forward, and some were facing outboard (to the left). I mounted mine with the primary's facing left because my manifold is a dual-plane, and I reasoned the primary's would service one plane, and the secondaries would feed the other.
I'd like to read some idea's as to which way is better, or if it even matters, and why......

Thanx!
