Denis,

I have tried them all! Sort of....see my first posts above....

One common thing to ALL of these manifolds and a Holley Carb....getting an automatic choke to fit is the pits!!!! I have not yet solved this issue yet....

Here is my rundown:
Old style F4B: These are a copy of the "Ford-Shelby" intake sold over the counter, sometimes known as "C9OX" intakes. The center two runners are "HIGH" near the jackshaft and require a LOT of clearancing on an expensive bracket to make it work....

New Performer: Seems to fit with minimal modifications necessary. You may run into a "radius" issue at the front most intake bolt boss where the jack shaft bracket fits against it. Slight amount of file work will clean this up nicely.

New Performer RPM: Same notes as regular Performer.

Both of these intakes have the runner design reversed, so there is little to no interference with the jackshaft bracket.

There MAY be some fit issues with your front RH idler pulley bracket in the way that it fits with the front two support holes on the jackshaft bracket.....

I am using NOS parts to fit my new stuff together and as shown in one of my pic's above, the holes don't line up, even with a stock intake!!! Jury is still out on this one..... I may end up having some holes filled, and redrill them where they need to be...

Also, at the rear of the new intakes, there is no boss to attach the stabilizer leg of the jackshaft bracket.... I am going to have a boss welded on mine, once I figure out which one I am going to use!

Either or all three of these would appear to fit under the bonnets just fine with the stock air cleaner. I have pictures from other guys that have either the F4B or the Performers installed.

The Edelbrock Victor Jr series manifold is one that I wouldn't recommend installing if you want to retain the jackshaft. The one installation I saw of this version is missing about 6-8" of the center of the jackshaft bracket all together.

All in all, the stock intake, with the 1" spacer is a very hard intake to beat. The ports are large and everything fits.... it is merely the weight that is a factor!!! If only someone simply cast up a stock intake in aluminum, life would be a whole lot easier when it comes to an intake swap on a Goose!!!!

.....my frame work continues, just haven't had a chance to post pic's!!! Need to work on my ladder bar, hopefully next weekend, to get some machining done, and then it will be some finish welding, and some tidy up of the weld areas, and on to paint...or sanding, sanding, primer.... then pain.... I mean paint!!!

Ciao,, hope this helps!
