LEMONS HEADERS INC.
’78-’87 G- BODY SMALL BLOCK RACE HEADER
PART # SBR-145
Header Spec’s:
This header is designed for any tube size up to 2 ¼” with any collector size up to 4” or our collector muffler up to a 5” size. The design has 2 tubes on each side that go around the frame. The engine needs to stay in the stock location.
What Fits:
We used Moroso frame mounts #62630 and Moroso motor mounts #62515 to locate the engine. The header will also fit motor plates. This header will fit almost any mini starter except aMezier #400 and will not fit a factory GM full sized starter.
We offer Power Master #9540 starters.
This header has approximately 5” of room on each side of a stock oil pan for kicked out sumps. This header is designed to be used with a skinny drag racing type front tire for maximum turning radius. We held the header and collector up as high as possible for maximum ground clearance, if you will have a large exhaust system we offer a Chrome Moly transmission cross member for added clearance. This header will fit a power brake booster, but your master cylinder brake lines will have to be rerouted. It is not intended for use with an air conditioning box on the fire wall, clutch linkage or column shifter linkage.
Installing the headers:
If you are going to be using your inner fender wells they will have to be trimmed to clear the tubes around the frame. Make the opening large enough that the header can be taken in and out.
Before trying to install the headers lay all the tubes out on the floor to orient them to their proper position.
Driver side: Install #1 and #7 from below, snug the header bolts only do not tighten them. Next install the center pair these are the tubes that go around the frame. Then install the collector and go back and tighten all the header bolts.
Passenger side: The Pasennger side will be the same sequence #2, #8 fron the bottom then the center pair. You may have to remove the starter, be sure to reinstall the starter before the tubes are bolted in place.
Refer to our (Header Installation Tips) page for additional information, it will make installing much easier and save you time.
