427 SOHC help.
Hello. I have a 1966 Fairlane GT and am wondering if anyone makes aftermarket SOHC parts, heads, etc? I already have a genesis block, just want to go more wild.

SOHC parts
Several people are supposedly tooling up to do new SOHC heads in
aluminum. Other cammer bits and pieces aren't that hard to find, but
VERY pricey. A new cammer build will probably be in the mid $30's at
a minimum. NOS cammers appear from time to time, quite pricey as well!

I have a builder friend with an original set of aluminum cammer heads and he turned down an offer of 6 grand for them,he also has a gear driven timing set up instead of that 7 foot chain that is usually used, that gear drive is simply NOT for sale... so when Fred says pricey.............

An interesting foot note on a 64 Thunderbolt 427 CENTER oiler with the very first Hemi Heads:
This car number 10, is even rarer. It was Ford's first experiment with a Hemispherical head engine. Car number 10 was the second "Thunderbolt" sold to Mickey Thompson for $1.00. He also purchased car #7 which was driven By Butch Leal as an unaltered factory original. It was the car #10 that Mickey entered into a contract with Ford to design and engineer a hemispherical head version of the Ford 427 Center oiler engine. The heads were cast from Chrysler hemi heads and machined to fit the Ford block. The intake manifold was designed with the carburetors side by side. The name "Thompson" was cast directly into the valve covers.

The intake in the picture appears to be a ram induction unit (the right carb feeds the left engine bank, etc.) as used on the two Paxton Supercharged Cobras. It's possibly a modified FE unit, but that's obviously a guess on my part.

Dan are you saying there were 2X4 side by side intakes available or used on an FE BEFORE or during 1964?
Perhaps this is also the FIRST example of such an intake (side by side 2X4). Makes me wonder now what the source was for Shelbys twin paxton setup in 1965 or 1966. Where did HE get his manifold?
JOKER21, go for twin 4's side by side on that SOHC application, that would really be different!  |

Gerald Coon makes billet stub cams, teflon chain guides and other misc. parts.
Rotophaze has cam cores that you can send to Crane.
Kevin Jackson should still have some things available.
Spark plug tubes, cam bearings, and timing chains are available reproduction.
I'm working on a mold for spark plug boots.
If you're really after power get a sheet metal intake made. (Hogans)
What other parts are you looking for?

The Shelby twin Paxton (actually McCullogh) used an Edelbrock 2x4 crossram.
Mickey Thompson produced 2x4 crossrams for any number of engines including the FE, BBC, Pontiac...
The Edelbrock crossram allowed the use of the stock (or at least a regularly driven) distributor. The M/T crossram for the FE required the distributor's drive be extended, with a spliced in piece. This led to some spark issues at higher rpm's when using the M/T manifold with a distributor. |

Ernie, the keyword in my post is appears. I can't find a quality picture of the crossram used on the Paxton Cobras, but you can make out the runners on this one, while under restoration:
The crossram was the first intake to make one hp per cubic in. on Edelbrock's dyno in the late '50s, on a smallblock Chevy such as this one:
The intake on the Cobra appears quite similar to the one on the Thunderbolt you posted; you may have to enlarge the image.

Here is the custom SOHC Weber manifold built for my cammer car by Hogan's Manifolds in CA and being finished by Inglese Inductions in CT:

Well, after much consideration I believe I have decided to bore and stroke my engine to somewhere near 520ci, and I believe I am going to have hogans make me a 2x4 intake. I wanted a SOHC, but the engine alone is around $35,000. A bit too pricey for me.

An interesting topic, this history of cammers, Hemis and 2X4 intakes. |
