Header Specs:

This header is designed for any tube size up to 2 ½” with any collector size up to 5” or with our collector mufflers up to a 6” size.
It was designed on a stock chassis with an aftermarket “K” member ( BMR or AJE ) and with motor plates only, no side motor mounts ( we can clear BMR side mounts ). The engine must stay in the stock location.
All of the tubes are inside the frame with good ground clearance and spark plug access. It requires a mini starter a full size GM starter will not fit. A Power Master #9500 starter has the most room. Measuring from a stock oil pan on the passenger side we have 2 ½” at the top and 3 3/8” of room at the bottom for an oil pan sump kick out. On the driver side we have 3 ½” of room. The driver side with a large tube size is close to the steering column, you may have to replace the factory rag joint with a smaller “U” joint.
This header will fit with a hydraulic clutch system only and is not intended for air conditioning or column shifter linkage.

Header Installation:

This chassis is very confined especially on the passenger side. We build this header with individual tubes and a slip on collector for easier installation.
Install the tubes on both sides starting from front to back, only start the header bolts so the tubes can move freely until all of the tubes are installed then snug the header bolts, but not tight until the collectors are installed then go back and tighten all the header bolts.
Refer to our header installation tip’s page for additional instructions.
