Long Tube Headers with a Dropmember

[biketopia]

I know headers and ground clearance get brought up often, and many say use the Chevelle headers...with a BBC. I'm running a big cube SBC, I need to run long tubes. I am also using a No-Limit wide ride kit. I called No-Limit, and they suggested headers from Headman or Sanderson for the C-10 application, but couldn't give insight into ground clearance.

So, those of you with a SBC, and preferably with a drop member, what brand/application/part number of long tubes are you all running that tuck up nicely in the frame rails? The truck will be static dropped on coil-overs.

I don't believe S10 headers are what you're looking for. The only long tube ones currently
available are fender well headers. The rest are mid-lenght headers. I recently spent too many hours searching for S10 headers.

I recommend reaching out to the tech guy at Century Performance he helped me get my new ones for my S10.

Below are some photos of my Burban's headers which I believe are A--body headers. They however didn't clear the frame or the engine stand so the PO used torch to clearance those items.

I used Patriot H8048 headers on an 82 C10, but I've heard they will fit 67-72. They have 1-5/8" primary tubes and 3" collector.

You can see how well they tucked up. Much higher than Hedman and Hooker.

Thanks for the recommendation and pictures! Any idea on the manufacture of the headers on your Burban? Having the No Limit cross-member plus a tubular trans mount may free up some space on my setup. I'm kind of keeping an eye out on marketplace for a cheap set of headers from a known application to pick up and just see how they fit.

Those aren't bad. Noticing many manufacturers state their headers will fit both 67-72 and Square body truck applications with one part number. The Hookers I had on it in high school had the top of the collector at the bottom of the frame, hanging way down under the truck.

According to No Limit's tech documents, the bottom of my frame under the cab will be about 5" off the ground.

Sorry, I've got no idea of the header manufacturer. The PO said he took them off his 71 Chevelle drag car when he stepped up to larger ones.

Hope you have some smooth roads where you live! Or stiff or limited travel suspension.

Had a buddy years ago with an Mazda RX7 that was so low, he had to push it in and out of the driveway so it didn't bottom out on the sidewalk. But it won some autocross trophies!

Hope everything works out for you. That truck should handle like a slot car!

At 5" I would plan on removing the 3 bolt flanges from the headers and use truck bands or weld some flex joints on. Grinding the flanges on the pavement only leads to exhaust leaks.

I think my white OBS '99 SWBCC has ~5" of clearance. The front frame horns don't clear a 4" parking lot space curd/barrier.
My dually is 4-5".
My Malibu is <4.
My '64 is 4" @ the rail (front cab mount).
My Model-A is 4-5" under the front dropped axle.
Miata is ~4" & the only one not lowered yet.....

4" clearance & things are fine w/most roadway stuff but you learn to be more aware of the road. Less than 4" requires slowing down for bad spots as you go. You tend to have select routes to places you navigate .

I'm thinking you should change your screen name to Low Rider!

Seriously, which methods of lowering (on front coil spring vehicles) have you found to work the best?

I've had lowered vehicles off and on forever, so I'm not at all concerned with this one. My Camaro had about 3.5" at the lowest point of the exhaust, with how unfriendly they are to tuck it up close was never an issue. With mine being a static dropped truck, I'm not really concerned about clearance. I appreciate others' concerns for it, though!

The exhaust will have V-band connections for easy serviceability and increased clearance. Now if I could just settle on a header that would slip in and give me what I need, without paying thousands for a set of Lemons

One of the main priorities is building an exhaust system that is no lower than the frame rails. Obviously, it can be a challenge when it comes to full length headers & larger diameter pipes. The cars are more of a struggle vs these trucks though.

I bought a set of the g-body sbc Hooker 2551's for my Malibu. I'll see if there's dimensions I can share once I move things around.

Appreciate it SCOTI!!
