I'm doing a V8 swap in my 54 bel air. Would anyone know what long tube headers work well for this? I know there may be some clearance issues. Does anyone have experience with long tube headers? I see a lot of pictures with the Sanderson short headers but not much with long tube headers

Thank You

Nobody makes a set of long tube headers for a V8 in the stock frame of a 49-54 chevy car. This is why I suggest an early Camaro or Nova sub frame swap. You get a suspension upgrade and an assortment of exhaust options.

I went with fenderwell headers. These are the only store bought long tube headers that will work......BUT......they will not work with the stock steering. I installed a Heidt suspension also.

That is correct, there are no headers for a V8 in a 49-54 Chassis. SOME cast iron exhaust manifolds can be used with some trimming of the firewall braces, removal of the 49-54 style emergency brake linkage and a VERY GOOD, VERY EXPERIENCED muffler guy.
When I first installed a V8 in the 51 over 50yrs ago, I used 64-68 Chevelle/Camaro style manifolds, because they have a bracket for an alternator on the left manifold. NO, I'm sure they are not as efficient as a good set of headers would be, but they do a respectable job for my needs.

Even later style manifolds that have a similar style to the 55-56 manifolds will also work. But I do not like those because the spark plugs are not as easily accessible.

Over on the HAMB, a member "deto", modified some later model Camaro headers by cutting and welding on a new collector. I don't remember the specific year headers he used, and he has't been on the forum there for a while; there are NO bolt in, long tube headers, made for these cars (49-54), and the Sanderson's are't really a performance set of headers. They are designed to "work" for a swap. We used a set of "96, baby LT1, Caprice cop car manifolds". You have to remove the tin covers, plug/weld a couple of AIR ports, and drill another mounting hole for earlier heads (7 bolt heads to 6 bolt). These manifolds have individual runners, sweep up and then drop down at the rear; they are essentially a cast iron header. You still have to modify the firewall supports for clearance with them however. They look good, fit good, make power, and are what I'd use in building a 49-54 Chevrolet; we used them on the 51 Bus Coupe. They are used on some Camarons/Firebirds, trucks, and full size cars, and are available new from the aftermarket.

May be no help, but with a Fatman frt end, Ram's horn center dump manifolds fit nicely. Rack and pinion clears up space of course.

I think the 56 style manifold dumps in the front on the driver's side? These both dump in the rear.

The top manifold in the picture that I posted is for the right side, when it's turned around to be installed on the right side, and it dumps at the rear.

Yes, I guess what I'm trying to say is 56's dump in front and in the rear. The Williams both dump in the rear. Has anyone tried these?
