#BBR-505 BB Race header for stock chassis with stock steering box
$1,750.00 – $3,850.00
This header is designed for any tube size up to 2 ½” with any collector size up to 5” or our collector muffler up to a 6” size. It has all the tubes inside the frame with excellent ground clearance and spark plug access. On our design car we used a Milodon low profile oil pan #30950 and #30955 to design with and the bottom of the header was ¼” below the bottom of the pan. Measuring from the side of a stock oil pan we have 3” of room on each side for sump kick outs. This header will fit on side motor mounts or motor plates. Engine position is critical! Use small block front mount frame stands to position the engine with Moroso #62530 solid motor mounts. Rubber or Polyurethane motor mounts will have to be trimmed for clearance. Ask our sales person for more information. Any mini starter will fit, but a full size GM starter will not fit. The header tubes are to the outside of the oil filter so if there is no oil pan kick out on the driver side the filter is easily accessible, but if your oil pan kicks out under the filter it will be trapped and you will need a remote filter. If you will be using our collector mufflers you may need our tubular transmission cross member #CAMX67 for additional room.
This header will only fit up to a 7” power brake booster and is designed for clutch linkage, but it will NOT fit factory air conditioning or column shifter linkage. If you are using a Lakewood style scatter shield you may have to slightly trim the outer edge of it under the starter area.
We normally build this header with individual tubes and slip on collectors for easier installation. Remove spark plugs, oil filter and starter. On the driver side motor mount frame stand you will have to trim the back top corner at the base of the mount to clear the #1 tube (see drawing).
Driver side, start with #1 and #3. Install them at the same time from the top. With big tube size or a kick out oil pan you may have to raise the engine slightly to get these two in. Get the header bolts started. Next install #7 from below and start bolts. Install #5 from the top and snug all the header bolts, but don’t tighten them until the collector is installed then go back and tighten all the bolts.
Passenger side, install #2 then #4 from the top and start header bolts slightly leaving the tubes very loose. Next install #8 from the bottom and start bolts. Install the starter (the size of the oil pan will determine the difficulty to install the starter). Then install #6 from the top. Snug all the header bolts, install the collector and then tighten all the header bolts.
