Headers vs 340 manifolds

I was specifically asking MopaR&D as I saw he was going from the shorties to the Dougs. However, anyone who has done both is more than welcome to chime in and your input is much appreciated.

The reason I asked is that I have a mild 300hp 318 (ie; built from the old 318 Street Recipe mag article) and have been debating on which way to go for my Barracuda that will be 99% street and I later plan to do a Gen III swap. The shorties are a lot cheaper and would probably be fine for what I'm doing I think.

I think you'll be fine going with shorties although you want ones that aren't "block hugger" type with the outlets pointing straight down; having the outlets angled backwards instead will be a great benefit because you can have smoother bends with the downpipes and keep them the same ID as the collectors. I had to use angled collector extensions from Sanderson iirc to make it all fit with the Hedman Tight Tubes which required the diameter to neck down right off the headers.
