click the images to see a larger size photo
This header is designed for any tube size up to 2 ½” with any collector size up to 5” or our collector mufflers up to a 6” size. Three tubes on each side go around the frame. The position of the engine is important for proper fit. This design requires motor plates and a rack and pinion steering. Attached is a diagram showing the required engine location. The steering column will have to be lowered where it comes through the fire wall. The back side of the “K” member will have to be notched for the oil pan sump. This is a very complex engine swap.
This header was designed using a Tilton starter. Oil pan room is limited on the passenger side to 2 ½” at the bottom of the pan only, on the driver side we have 3 ½” of room top to bottom. Spark plug access is very good you can get a socket on all plugs.
This header is intended for race cars only it will not fit air conditioning, power brake booster or column shifter linkage etc. Skinny drag race type front tires are needed for maximum turning radius.
Passenger side: install the #2 tube from below with the starter out. Before bolting the tube in place reinstall the starter. This is the only tube inside the frame on this side. Next install #6 then #4 then #8. Only snug the header bolts don’t tighten them until the collector is installed then go back and tighten all the header bolts.
Driver side: Install #1 tube from below this is the only tube on this side inside the frame. Next install #5, then #3, then #7, then the collector.
