LEMONS HEADERS INC.
’68-’72- CHEVELLE- BB RACE HEADER
PART # BBR-545
Header Spec’s:
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.

What Fits:
We designed this header with the engine in the stock location setting on small block frame stands for the front motor mounts with Moroso #62510 solid motor mounts or Prothane #7-505 polyurethane motor mounts. It has 2 tubes on each side that go around the frame which will require that you trim your inner fender wells for clearance. It also allowed us to get the best possible ground clearance, oil pan room and spark plug access.
It WILL fit motor plates, aftermarket “A” arms and a power brake booster, but it will NOT fit a factory air conditioning box on the fire wall or *column shifter linkage. Factory clutch linkage will have to be modified to work (ask our sales person for more info.). A deck height and raised exhaust port combination of 1” or more may require moving the steering column outward for clearance. It is intended for use with skinny drag racing type front tires for maximum clearance with the tubes around the frame. Your master cylinder brake lines will have to be rerouted for clearance.
This header will fit almost all mini starters except a Mezier #400, and will not fit a stock GM full sized starter. Available oil pan room for kicked out sumps, measuring from the side of a stock oil pan we have 4 ½” of room on both sides. The oil filter is very accessible and the starter can be removed unless you have a big pan kick out. Spark plug access is very good we recommend using a 45 or 135 degree angled spark plug wiring boot. We hold the headers and collectors up as high as possible for ground clearance. The bottom of the header is even with the bottom of a stock oil pan. If you will be using a large exhaust system we offer a replacement chrome moly transmission cross member for additional exhaust room.
We carry Power Master #9540 starters.
Installing the headers: It is important that you read our Yellow (Header Installation Tips) page before installing your new Lemons Headers, it will make the installation go easier and save you time

Driver side: install #1 then #7 from the bottom and snug the header bolts, but don’t tighten. Then install #3 and #5 these are the tubes around the frame, snug the bolts. Now install the collector and go back and tighten all the header bolts.

Passenger side: install #2 and #4 from below with the starter in place, then #6 and #8 these tubes go around the frame, then install the collector. If there is such a thing as an easy header to install this is it.

Thank you for selecting Lemons Headers!
