Keith Dorton intake/header combo

Post #1 by Bill in SC » Sun Feb 28, 2016 9:02 am

Anybody run one? I have an old friend here in town that used to make similar ones to race on dirt tracks... He said if I got the flanges, he would make me one...

I've long thought that would be a great way to build a setup, as long as major tuning changes were not in the plans.
It gets 10MPG, but goes up to 14 if I lie.

That's similar to what I'm doing with my two 240/300 projects. My intake and headers are a different design but I'm building them using a 1/2" thick steel shared head mounting flange. I'm just starting on these. I've started on the flanges.

Image

My 300 is going into a E350 van. It's getting a 2-2V design intake. For the header I'm going with a modified tri-Y, single outlet, mid length design. This one the collector is going to be right in the bellhousing area ( over the top ) .

My 240 project is going in my 54 F100 4x4 project and it's getting a hi-rise 3-2V set up. This header is going to be a long tube design that I'm splitting at the bell housing area. I'm going to have a second flange at the bellhousing, so I can unbolt the rear half of the headers. That way I can pull the rear half, if I need to work on the transmission, clutch etc. That will make life a little easier then having to pull the whole intake and header assembly.

If you are interested, I've got this one kicking around my shop.

1pc, it has 1 5/8" holes for all runners, both intake and exhaust, cut from 3/8" steel.
Image

I cut this pair quite a while back, the 2pc went to Clintonvillian, but I could cut another if there is interest.
Image

The 1pc is still in my shop.
Image

He used the exhaust flange to fix an old set of headers, and the intake flange to build his own custom sheet metal MPFI intake
Started on headers and efi intake today! -- FordSix.com

Not mine, but interesting.

Here is some pictures of a manifold setup my dad and I built for a 300 in a pulling tractor.

This one was bouncing the web a while back, and is kinda-sorta what I was thinking:

I don't know if a carbureted version could keep the mixture from separating but the BMW ETA intake design folds 550mm of runner where the I-type fits 360mm. Stock EFI 4.9L intake would seem to be a decent basis, but reasonable side draft carbs are scarce here.

To be clear.. I was offering to mail you the 3/8" plasma cut 1pc flange for the price of shipping.

About that blue one, it sold on eBay a while back and one of the forum members bought it.
I snagged these pics from the auction.
Image
Image
He resold it because he was concerned that fuel would pool in the intake runners that drop down and then come back up for ports 2, 3, 4 and 5.
