Hot Rods Full-fendered Model A Header Options

I'd like to see photographs of the different ways headers have been handled on full-fendered, OHV V8-powered Model As, especially with full hoods.

It seems that the areas between the sides of the bellhousing and the inner sides of the frame rails comprise contested real estate, with lots of stuff competing for space. Ideally you wouldn't want to take exhaust pipes through there too, or isn't it that hard? I'd also like to see rolling frame pics showing the space available.

Has anyone devised anything (maybe something like narrowish sprint-style headers) which punch through the tops of the splash aprons just aft of where the aprons meet the fenders? Lakes style is pretty obvious so not much use repeating. I'm more interested in other approaches. What have people come up with?

 

Anyone?

 

My Willys headers I built that might, could, maybe, possibly fit an A.

 

With full fenders you can really drop the primaries low and gain lots of room with out anyone ever seeing. The side aprons drop quite a way lower than the frame.

I know I’ve seen a lot of early
Two piece headman headers on full fender A’s. I’d say as long as you aren’t run home g something wide like a caddy/olds/hemi the only
Thing you really have to work around is the steering

This isn't the best photo for showing how the headers came through the fenders because it was taken from a magazine, but this was a local car with handmade headers from back in the 60's. That oval behind the front wheel is the collector for the header

 

That's an interesting approach. Not sure it'll work for me, but worth studying.

 

This style is often used where space is limited. Called Tri-Y headers. You'll probably end up building your own.

 

I am considering using patriot headers. Part no. Is H8017-1. Full length headers they say will fit model a with SBC.

 

Thank you for whoever posted the other shots of Bill Wilde's car. I haven't seen that car in person for over 50 years and the old memory isn't what it once was.

 

Google Image Search wasn't hard.

 

Those statements are easy to make and if your Motor is mounted exactly as the one was they built the headers on you have a strong Maybe in your car. I see Amazon has them so it's an easy return.

 

Those wild headers are on a channeled car so it has nearly a foot less room.

Patriots are a good name as far as I’m
Aware. If you don’t want to build your own buy the headers and then add steering and cross members that will let them work I guess.

Seems like putting the cart in front of the horse but building headers really is pretty damn time involved and there are 1000 different ways to place every little part of the car. There’s no way to Say 100% that anything will fit
Unless you start with everything you want to use and make them fit.

any sort of block hugger is probably a good place to start though

 

My concern with the ones from Patriot is that the 2 end pipes stack in front of the 2 center pipes making them tight against the hood sides if they clear at all.

 

P and B
I don't know if this is an across the board policy but my experience has been some Amazon second party retailers have a 10 to 20% restocking fee.
I found this out even when they sent the wrong ($225) item.

 

This is a fact. Not everything form Amazon falls under the same return rules.

 

First I will say that S&S Headers are no longer in business but I have two sets of their 1&3/4" sbc headers that if I remember correctly were stated as fitting 28-34 applications.
One set is on my 32 roadster and the other set is for my 67 Nova that were modified because there were/are no underch***is 1&3/4" available, plus the car has been lowered considerably.
I guess my point is many times a non-app set can be used with some creative modifications.

As mfg.

 

I would buy them from Summit Racing, I try not to do business with amazon. I will not be using a full hood so the overlap won't be a problem.

 

Went out and took pictures to show how much room for H8017 headers. I ordered them earlier in the day. After taking pictures, I saw I had an email from Summitracing. They said those headers had been discontinued, what the F...! Now what? They have another set, like DDDenny posted. Anybody know anything about them?

 

Photos?

 

They look like they'd hang real low, like below the ch***is, maybe below scrub line. Maybe not, but just picturing how my engine sits in my A, and it sits pretty high, those look like they'd be the lowest part on the car.

 

Photos won't be much good now, they are discontinued. I found 4" from the front exhaust port to the hood line. The rear exhaust port is 6" to the hood line. Just got a smart phone not sure how to post pictures.

@Ned Ludd , what ohv engine are you considering for the full fendered A?
About every possible combination has already been tried and commercially available headers for most are available.

 

It'll depend on availability and affordability at the time, but I've got a short list of likely candidates, at the top of which is a wide Mopar B, as they are almost as common (or uncommon — they're all "exotic" here) as SBCs here. They were in Chrysler 383s, which were locally manufactured second-generation Dodge Monacos with the 383B. Further down, Pontiac 389, Chevrolet W, Olds 394, or whatever presents itself.

It might seem a bit back to front, but the routing of headers is going to have knock-on effects on a range of other design decisions, which I'd rather not have to do when I've got an actual engine sitting in front of me. An early decision to route the headers outside rather than inside the rails might allow me to accommodate a wider range of engine options within the same basic strategy. Though purpose-made headers are a given and there's more than one way to skin a cat, it's worthwhile looking at what other people have done.

 

That’s quick a wide swath of choices all of which will be a completely different situation header wise other than the fact that steering and trans cross member are the main obstacles. Though from my mock ups an early caddy and 394 olds won’t clear the hood at the front of the hood even with stock manifolds so if your concerned about that maybe rule them out unless your ok setting the engine back into the firewall quite a bit.

I know @Nimrod had a 460 Ford under the hood of his 29 but it was set back a couple cylinders deep to make it happen

 

We might see what @rjgideon is planning to use for headers on his Mopar big block T ch***is.

I don't mind blistering the hood sides quite heavily —the Mopar would need that too— and/or exposing the headers.
