Stock 340 Manifolds or TTI Shorties?

Yeah ! ! !

You get wayyy more than 10 h/p too ! ! !

The way people throw 10 h/p out there, doesn't matter 6 cyl or 512 stroker, it's always "only 10 h/p" ! ! ! BS !

I called TTI and talked to one of their techs (Sam). Asked him about the shorties versus full length headers. He said the shorties were designed primarily to deal with ground clearance issues. He said for me with my 408, I should definitely go with long tube headers. He said I should expect substantial improvement over the manifolds. Was enough to nudge me to the long tubes! I asked him about the lead time. He laughed, and said there is still quite a backlog (for TTI headers). Dougs headers, on the other hand, are in stock at Summit so I ordered them.
