I can tell you that putting any of those intakes on an adapter for a FE...you can throw all those numbers out the window. They won't mean a thing.

They called me for intakes. Most of those will not fit factory heads which adapter is made. Which I explained and they never knew. They were hoping to find the rare roush intake. So if they buy that one they will have to cut up. Why they are not using billet or fabricated i have no idea.

Scott. Im not saying you are. I know you did it you mentioned before.Thst intake you hsve there is no longer available.

All I'm saying is that even with the best candidate, it's a shit show. The port alignment just isn't there. The end runners are the issue. The ram has the best chance/will make the most power with the straighter end runners but any 351C single four intake is going to have the same issue no matter how good the intake is. The air has to make almost a 90* turn on those end runners. Not to mention trying to get enough area in the runners to feed more ci than the intakes were designed for.

I know the Super Stock guys use those wide spacers with the FE and a Cleveland manifold.

There are several of them. It was a big deal and the rules ended up getting changed to allow a spacer between the intake and head. So the SBC guys take advantage of it as well.
On Jay's testing, the Cleveland intakes on the FE did about what they do on a Cleveland. The Strip Dominator and Torker were way up there, along with the Tunnel Ram.

Don't know why they'd bother with that nonsense. All the SS FE guys I know of are running sheet metal intakes but my knowledge is limited.

They are probably running GT.. I could run a sheet metal in GT.
New rules this year says you can't run in GT unless you have a front wheel drive conversion car. So there are many guys having to switch back to SS. In other words a traditional SS car you have to run the proper engine offered for that car. GT you can run any combo you want.

What's the point? Marketing.
Problem is there really aren't any contemporary "good" single plane intakes for the FE. The whole adapter thing came about from a company called Pro Stock Engineering back in the 70's so you could run the Cleveland TR when it first came out. The Cleveland TR itself is outdated by decades, but it looks cool and makes -ok- power. The only answer, really, for making any serious power with an FE is a sheet metal TR but most of this is moot anyway because there's only a handfull of cyl heads with the potential to take advantage of any serious intake effort or make any serious hp/ci.

The FE manifold adapter to use the Cleveland intakes was done years ago by Pro-Stock Engineering - as well as a few other Ford FE race components. The idea was slightly modified and re-introduced a few years ago.
Port alignment is a big deal - and the outer ports are a fair distance away - not ideal at all.
Short of a sheet metal intake - perhaps a welded up Victor intake or a welded up Trick Flow single plane would work
for high rpm race use?
The tunnel wedge does seem decent for dual 4 builds.
I haven't seen anyone modify the existing single plane manifolds - perhaps someone has?

Paul is one of the go-to's for FE sheet metal intakes. That's not for Clevelands. Super nice piece.
This is the Jay Brown Cleveland adapter. It's hard to see in the pics, but the end ports are at about a 30* angle.
