IF you want to run something a little different and IF you have the 4v iron heads, you could also consider running a Weiand 1994 Tunnel Ram base with two Holley Dominator #6214 carbs.
The base is already a Dominator bolt pattern without the top. The carbs will bolt right up to it mounted sideways.
Originally you needed to run the 6214 Dominators with the 4 corner idles BUT if you mount a 1" open spacer on it, you can run a regular one with normal primary idles.
The height of that manifold is the same as was run on the Trans Am Boss 302's with the dual dominators.
That set up is as impressive or even more so than the Webers are and certainly make as much power.
ON THE PANTERA ONE thing you can do with the Weber IDA's to help with the fuel reversion is to use tall velocity stacks. 5" is about right.
What happens is that the "cloud of fuel" hovers just over the top of the stock velocity stacks. When you extend them to 5" high, that cloud tends to stay in the stack.
Randy Gillis calls that carb a Holley version of the Weber IDA. It works exactly the same way except for the addition of the power valves.
The spacers under the carbs will also give you a plenum by which you will eliminate the power pulse reversion of the cam, most of it anyway.
Plus your cost for jetting is reduced by 3/4 from that of the Webers.
Every so often I consider this and it becomes just an unnecessary expenditure but it definitely is something that will work and won't stick up any higher than the Webers do.
I don't think that you need an offset distributor with this because of the height of the manifold but I can't promise that. Ask George. This is his dream induction system.
Something to think about. It's a VERY nice dream to have.
What say you GP?
5" tall velocity stacks
