Header outlet/frame interference, SBC, RHS.

[Frank Pav]

The header outlet on the RHS of my SBC is pointed at the fore/aft tubular frame member exiting below the foot box. The exhaust pipe runs into this frame member. I am using the FFR recommended header, Summit SUM-G9005. I thought there might be some production variability but Summit says that the headers are machine welded on a jig and the millionth header is the same as the first. Am I doing something wrong here? Anyone else having problems?

I have the same problem. I am going to take the car and the pieces to a local muffler shop to re-bend the piece to fit correctly

I threw it all in the trash and started from scratch :( Couldn't get anything to run how I wanted. I really wanted to run side pipes but don't think will be high enough. Taking it to the local rod shop next week to finalize the suspension and hope they can get it up high enough for me to install. Will fit my style better.

I ordered a second set of headers from Summit, same interference. I clamped the original header to my welding table and used a heat wrench to soften the tubes and move the outlet inboard one inch. Got the exhaust system to fit with minimal clearance. I’m hoping the stiff engine mounts will restrict movement.

I relayed this info to Blueprint Johnny. He never heard of this problem before.
