Reply to "IR - Classic weber IDA or IDA TBI EFI?"

It's a 351w 2x4 Holley intake made by Price Motorsports.
What he does is mill off the front thermostat housing and water passage, mill the rear of the manifold to fit the 351c block, and build aluminum billet spacers to mount the manifold.

You would think that the manifold would need to just be cut to fit a 9.2 block but the engineering to match up the top of the ports requires spacers.

The set up is in progress. He should get to it this week. He's a busy guy. He's gonna' email me the picture of the spacers when they are done.

The ports on the manifold are the same height as my A3's but narrower. When they are done they will come closer to what I need on the width. You can't get the full width of the port because the manifold isn't thick enough BUT they should come to about what the width of the B351 head.

The manifold as it is cast flows 285cfm @ 28in of mercury. That isn't terrible and for a street manifold will crispin up throttle response. On a track it would surely suffer in the 7,000 to 8,000 rpm bracket at WOT but doubt it will ever get there?

Because of the spacers the manifold will not sit on the block. He has a cast aluminum valley cover for this and the result is it will look and work like an air gap set up.

Here's a picture of the manifold. It is available with both the angled carb base or flat. The flat will work best on the Pantera.

Oh, and all of this for $680. Not bad I say?

I can already tell you that I have the Blue Thunder 2x4 "high-rise" on my 68 Shelby GT350 (347/302) with 600cfm Holleys. To say it loves them is an understatement. It has to be the best running carburetored setup I have ever driven.

I would expect the Pantera to be nothing less and quite possibly hotter. This Cleveland has more cam, much better heads (A3) and 180 headers.

I would say that this set up will not fit under the stock screen or without cutting the decklid. Mine is already cut for the Webers.

By the time it is done it will resemble the GT40 MIV air cleaner set up with ducting to the window scoops and a big benefit is it won't be subject to sucking in rain or car wash water and soap. To me that's a big plus.
