Header Specs:
This header is available in 1 ¾”, 1 7/8”, 2” or 2 1/8” primary sizes, or we can make it as a step design. We can build it as a street or race header.
Collectors can be 3”, 3 ½”, 4”, or collector mufflers up to 5” diameter.
This is a hand made header, so we can make any combination you need.

What Fits:
All tubes are inside the frame with excellent ground clearance and spark plug access.
On our design car we used a Moroso oil pan #20140 and in the 2 1/8” primary size the header was ½” below the pan. Smaller primary sizes would gain ground clearance.
From the side of a stock oil pan we have 3 ½” of room on the passenger side and 4” of room on the driver side for sump kick outs. We used a stock GM starter. Oil filter access is very easy.
This header was designed on Dirty Dingo #DD3575C adjustable engine mounts, setting on stock small block frame mounts.
To position the motor we used a stock transmission crossmember and centered the tailshaft mount in the slotted holes. See photos of engine mount position.
This header will also fit motor plates.
This header WILL fit a power brake booster, but WILL NOT a fit factory air conditioning box on the firewall or column shifter linkage.

Note: It is important that you read our Yellow (Header Installation Tips) page before installing your new Lemons Headers. It will make installing the headers easier band save you time.

Header installation:
Driver Side: When we finished our design header we were able to remove the driver side header easily out the bottom.

Passenger side: We had to remove the spark plugs and starter and take it out through the top.
If we build the header with slip on type race collectors we can cut the header flange in the center, so the tubes would be in pairs, making installation easier.
