Any early A fans that can fab headers?

Looking at the spitfires, it seems it would be fairly easy to modify the basic paired design to get a true 180 degree 4-2-1 configuration with a 1 3/4-2 1/4- 3 collector. By pairing the outsides and then the insides and then finding independent paths out of the engine bay ending up in a 2 1/4"-3" (or 3 1/4") collector I think would not be overly complicated to design and build using flow master pulse tech D merge collectors.

The key is if you build them right you could expand the market not only to early A's but also late A, B and E bodys. Perhaps by flanging the pairs/down pipes to allow for modular chassis adaptations. This could be a big market for Stroker guys of all body styles.

Any body want to give it a go?
 
Here's my take on the concept. I just built a set of 2 inch primary, headers for my 440 powered 65 Dart. From start to finish between my time and materials, I'd profit maybe a couple hundred bucks. Not worth it when I can go to work for a 4 early, sit on my *** reading a book, and profit the same.
 
It's all good, I've got Stephen Daurity, he's gonna make them. He's an awesome fabricator, the wagon is down at his shop now.

What wagon are you builing? I'm building a 64 Dart wagon BB. Daurity does nice work.

This motor 4.25" stroke 440" 360 with ported W2's and a mild 251/259 @.050 .605" lift Bullet roller

That's gonna need a LOT more than Spitfires or similar. Why not go fenderwell headers?
 
Don't really want to run fenderwells but if we need to sneak s couple though that's what we'll do.

Stephen will figure out a way to get them in there, the TTI's design seem a bit overly long, torque is not gonna be an issue, lol. A 4-2-1 180 TTI-y with 1 3/4-2 1/4-3.25 would be about ideal. It's a street car all done by 5800-6000 with peak power around 5400.
 
Please keep up posted. I am building a 66 Dart with a 383. I think there are a few other guys building big block cars also.

By the way, nice wagon.

That's a street engine with those huge ports? I have a feeling you are going to be very disappointed in its low end torque. That engine will just be coming to life about 4500. You need to go with small port heads with short tube headers. IMO
 
A standard un ported (just a decent VJ, bowl blending and guide shaping) W2 port on a 340 motor starts pulling really nice at just below 4000 and pulls hard through about 6800. This is a 440 inch small block so proportionally the sweet spot will start coming on as low as 3200 and pull really well into the mid 5000's, the heads are ported to allow the motor to rev and not drop torque rapidly above the HP peak.

We just did a very similar design philosophy for my buddy's 442" AMC with similar size ports and a similar hydraulic (this is a solid but compensated for lash) roller and it made 545/545 with a torque curve as broad and flat as Nebraska. Ran 12.90's at 103 in a nearly 3800 lb w/driver jeep granny shifting at only 4800 rpm. (First pass down a drag strip, when he shifts at 6000 I promise it'll go at least a 12.20.

Headers are important but not as critical as many people think when the combination is well sorted. W2 doesn't need a lot of overlap (fifth cycle scavenging) to keep the holes fed. spitfires were far from ideal but I know they would at least fit. It's no matter now since Stephen Daurity is going to build a proper set. This is just gonna be a driver do I'm not too worried about over 5000 rpm

I didn't want to leave much on the table but I was willing to only because I had the motor before I found the car, fortunately I hadn't speced a cam yet.

With respect, y'all.....I've got a 'pretty fair' level of experience with strokers guys,
Been building them for close to 30 years and can predict within about 5 hp what a motor will make. I've got a 517 low deck bbm, a 427" sbf and a 414" SBM in the garage right now. Check out wizerulz on YouTube.
 
as for the W2 port size, it's probably borderline big for 340" on the street but not for a 440" Stroker small block, the port size is essentially as cast just cleaned up a bit. 90 % of the work to these heads is in the boles and the valve job

4.25" stroke is a loooong way down

Sanderson is making a set that are nice and affordable. I'm running the dougs and they are a pain in the ***.

From the looks of Sandersons website, those headers are for 67 and up A bodies. You really had my hopes up, lol. Eric L
 
They are not listed on their site. Trust me all I have is 65's and they have them. Just call and ask them. Why they are not listed online yet is beyond me. I actually held a set in my hands at the goodguys show in Pleasanton Ca. If I hadn't already bought my dougs I would have got those. Think they were around 400 bucks or so non coated.
 
Seems I recall other posts on the Sanderson's and they are small tube, as in inch and a half. I can't see them helping much on the Wise Man's 440 stroker combination.
