Header Specs:

This header is available in any tube size up to 2 ¼” with a 4” collector or a 5” collector muffler. Designed for the Alston front clip it will fit side motor mounts or motor plates and the front sway bar kit. The steering column must be installed per Alston’s installation manual. Because of the large tube size this header was designed for we run the 2 center tubes on each side around the frame. This allowed us to keep plenty of oil pan room. Measuring out from the bottom of a stock oil pan we have 4 ½” of room on the driver side and 3 5/8” of room on the passenger side. The oil pan we used on our design car was a Milodon # 30900 which has a 1 ½” kick out on each side and we could still get the oil filter in and out. This header requires a mini starter, either a Hitachi style or a Nippondenso style. A full size GM starter will not fit.

We offer Power Master #9540 starters.

This design has very good spark plug room, some of the plugs can be removed with a socket and extension and some will require a socket and an end wrench. Ground clearance on both sides is excellent. The design header ( 2 ¼” tube size ) was ¼” below the Milodon pan, smaller tube and collector sizes will have more ground clearance.
This header will not fit factory air conditioning, clutch linkage or column shifter linkage.
Header Installation:

Because of the tubes around the frame we use our slip on type race collectors. The sequence for installing the headers is the same for both sides. With the engine in place install the front tube first from the bottom, then the rear tube from the bottom and last the center tubes which go around the frame. With the header bolts snug but not tight, install the collectors, bolt them on then tighten the header bolts. Installation is way too easy!
