Ciao!

Spacers are by Edelbrock. Yes the air cleaner fits under the hood.

That is the Blue Thunder repro of the original Ford high rise manifold.

The '67 Trans-Am Coupes used the C6OA lettered 2x4. There were only 2 '68 302TP's both run by Shelby.

If you look at them vs. this one, those runners are rounded and flow more. It was made for the GT40 heads, C6FE, C7FE casting numbers.

According to Randy Gillis, flow testing showed that mine, the rectangular runners couldn't flow what the "as cast" GT40 heads did.

He also said that flow tested showed that no matter who ported the standard heads (like my 302 4v's) they couldn't be made to flow what the as cast GT40 heads did.

So Ford redesigned the manifold with round runners that flow matched the heads.

For me, this manifold with (if you noticed) the '85 "Motorcraft (Holleys)", converted to Holley side hung bowls, work NICE!

I think the secret is the 427 Ford linkage that makes the carbs progressive.

The fact that the main jets are #59's says something right there?

This set up gives you around 25 mpg simply because the linkage has you running on the primary/primary until about 3,200rpm's.

Now this is also a 347 stroker built into the original J code heads, balancer, block and distributor. Same as a 'goose.

The heads were race ported and the manifold was matched to it, 1.94 intakes and 1.60 exhausts and the thing just boogies! Big Grin

This would be such a nice set up in a 'goose, except maybe for all of the bent chassis components it would cause? Roll Eyes

This is the 67 289 Trans Am manifold. See the rounded runners? Now look at mine with the rectangular runners.
