Tri-5 swap headers?

Has anyone ever tried these? They look like they might just fit and I found a set of ceramic coated ones for a great price here locally... Looks like they would flow very well and they have O2 bungs in the collectors + I dont have to make an EGR block off for my 98 f-body manifolds. Im still a few weeks out from mock up.

I have not tryed them, but no I do not beleive they will fit the truck chassis. The tri-5 cars have the crossmember well forward.....crazyL

Re: Tri-5 swap headers?

based on my fitment, I can't imagine those would work unless your motor sits pretty high.
The primaries are too long before they kick back, and would most likely hit right into the perches. Manifolds for these truck swaps need to kick back almost right away, and tuck back and in. Thats why some of the tbss and fbody and camaro stock manifolds seem to fit the best. The cast design eliminates the long primaries and lets the exhaust start heading towards the rear right away.

#1 and 2 primaries will definitely give you problems.
