FE Intake Adapter

[jayb]

I'm machining #67 now; I haven't done much in the last 8 weeks because of the Drag Week thrash, but am now getting back to the normal production rate.  If you are in the mid 80s I should have yours done in November.

I keep reading the updates but I have apparently missed the pricing and ordering info.  Is there some other way to communicate with you on this?  Email perhaps?  I have 427 hi riser heads on mine.  I believe I have read somewhere that you have an adapter to fit these.  Am I correct?  I am wanting to use a weiand tunnel ram on this.  Is that workable with your adapter?  My name is Randy Kuhnhoff and my email address is rkuhnhoff@fspp.com if you would like to respond that way.  Thanks!

Randy, the pricing and ordering info is at the link below, in the Vendor Classifieds section:

You can also email me at jayb@fepower.net if you want to talk directly. 

For the high riser heads, I can machine an adapter so that the standard 351C intake will fit, but the tops of the FE ports in the adapter will be below the tops of the high riser ports in the heads.  This is kind of counterproductive from a flow standpoint.  A better solution would be to move the ports in the adapter up so that the roof of the port in the adapter matches the roof of the port in the head, but then the problem is that the ports are positioned wider apart on the adapter, so the manifold will not just bolt into place.  The solution would be a spacer plate, that would go between the tunnel ram and the adapter, but I haven't machined anything like that yet.  In fact I'm still kind of in the middle of developing the machining operations for the high riser version.  I might be interested in doing a spacer plate to make a 351C intake work.  I'd suggest you just email me and get on the list for one of the high riser adapters, and then we can figure out how to proceed as I come to your adapter.  Thanks for your interest in the product - Jay

Thought you folks would like to see one of Jay's adapters in process over here.  Making it fit onto a set of Blue Thunder medium riser heads with the large intake port.  Adapter was originally intended for a different port - so we have to change things a bit.  That's where John Marcella - the intake welder - comes in.

He added material to the floor of each runner to allow us to blend up into the higher position of the Blue Thunder port.  We had already port matched the Cleveland tunnel ram outlet to the adapter - so the weld is a built up "ramp" that is +/-5/16 tall right at the exit.  The welds are darn near smooth enough to tootsie roll....

Then he added material to the top of each runner to give us a place for the gasket to seal - the BT heads have a higher roof opening that - while "port-able" would have not allowed any sealing surface up there once done.

The tunnel ram has its own short story.  Before we cut the extra stuff away we decided to have Marcella weld some supports in between the runner banks.  The thought was that the intake might "spring apart" some once we removed all the metal connecting the sides.  John cannot make anything simple - not in his nature - so the welded in front and rear struts have arc shapes so they look sexier...

Overall looking pretty cool and wanted to share.  Milling the welded flanges flat again, and then finish porting at the head end...

The only comment I can come up with is dirty, very dirty.
Really cool Barry.

Wow! Looks great. All I can say is.....it takes a lot of balls to take a brand new part and do that much welding to it!

Looks pretty good, Barry.  Just as an FYI, I recently completed one of the high riser castings for high riser customer #1, who also has the BT medium riser heads.  Using the high riser casting there is plenty of meat available over the top of the Blue Thunder ports, and I did the CNC porting program to match.  Basically, I machined the high riser casting as a medium riser, but with 0.300" over the BT medium riser ports, and the BT medium riser port sizes on the head side of the adapter.  See the pics of this particular adapter at the bottom of the first post in this thread:

Also FYI I've cut several of the Weiand tunnel rams, removing the bottoms, and have not seen any evidence that they spring apart.  But the welding on yours looks pretty cool, probably worth it for bling factor alone LOL!

I had the same thought about the intake warping once cut out, my intension is to leave some webbing between the front and back. I am also considering removing the material between the ports on the side for better air circulation, I am thinking that leaving some webs there would not hurt either. I would imagine with welding on all that will require some milling to true it up also so am not going to remove all the welding as my ports will end up being Cleaveland 4V sized in the end. Fortunately the Trick Flow Box R base is already set up for the 2V/4V port already so a little port work is all I need to make the transition. The nice thing about the arrangement is that later when I get the heads ported the intake and adaptor is already sized for the larger port.

I would post pictures of my intake but can`t figure out how to post the picture?

OKay, The wife came to my rescue for posting pictures. This is manifold # 60 with a Weiand tunnel ram. Notice no braces, it didn`t move when I cut the bottom off. These manifolds appear quite stout. I thought I`d try out the looks of two different air cleaners. The carbs are modified 3310 Holleys. Still working on linkages. I`m kinda thinking of running this setup on my 63 Galaxie for next yrs FE reunion, but who knows. It would hafta be hoodless if I do.

Looks awesome!!!! I want to take the same open approach with my base, like carving a pumpkin LOL.

ive cut and modified my weiand tunnel ram and it hasnt moved at all. it is pretty strong and the runners havent moved after all my torture to it
