How rare is hilborn for a mopar?

Thanks, I will be looking at the set up in a few days. I will keep you posted in. He says it is missing the pump, Does anyone know what pump they reccomend for this setup. I looked at Hilborn and their pumps average about $500.

In case I p*** on it I will let everyone here know about it.

They are still building them and using them today. I can't imagine they are that rare.

 

Pumps are sized to motor displacement, or on blown engines, blower size and overdrive.

For a 383 you are between a 0- pump and a 1- pump. I run a 1- on my motor, but for gas in a 383, a 0- will be just fine.

Used pumps are hard to buy. New pumps are expensive. If you buy a used pump, send it to kinsler, hilborn or any of the host of other reputable outfits that will test and fix it. Just be careful, there is a lot of really bad used up circle track stuff out there. The pump should turn over stiff, maybe one finger on the end of a 3/8 wrench, but not feel like its full of sand, and not spin easy by grabbing the spud.

 

So what problems if any would result from using the manifold for a wedge head on a regular head? Since the intake port would be larger than the head port?

First we need to get the nomenclature correct. Wedge is the shape of the combustion chamber on 350-361-383-400-413-426W-440 mopar motors. As such, the term wedge is often used to describe any non-hemi in the mopar family, to distinguish them from the hemis. It is also the shape of the combustion chamber on most other motors, like the small block chevy, but the term isn't needed in the chevy world as they don't have to clarify the difference between them and other motors.

Max wedge has come to mean the 413CID and 426CID wedge motors that mopar made between 1962 and 1964, rated at between 410hp and 425hp. They were the most powerful wedge motors to come in the factory wrapper.

So, to install max wedge intake (hilborn or other) on a standard wedge head. First, Max wedge heads have no heat crossover, so the intake often has no provisions to cover the hole in the middle. Second, the gasket sealing around the ports is a little tricky. All the crossram equipped mopars I have had (and that is quite a few) always have had sealing issues. Hasn't been a problem with the injectors though (2 piece manifold helps a lot). Judiciously used RTV and proper torque are important, but with the injector, vacuum leaks are less critical.

If you do buy a max wedge injector and want to trade for my standard port, we could work something out...

bit of a problem in the flow department

 

A little porting and it should be fine.

 

Was it a difficult modification? I'm going a bit mad trying to find good alternatives to the Packard's awful four-barrel manifold and microscopic WCFB carb...

 

I had a Hilborn gas set up for a wedge years ago. The proximity of adjacent ports put the ****erflies close together so the ram tubes had to be special angle on the bottom that made them angle out away from each other if they had much bell at the top.
Also, the manifold was straight out from the head with no upward angle either, so the ****erflies faced each other on the opposite head making the ram tubes to also have to be bent so they would point up if they were long enough to hit the other side.
Bottom line, ram tubes for one of these are not straight off the shelf cut to length like fit everything else.

If it is 2 separate pieces it doesn't matter if it is low deck or tall deck. That's why they built them that way.

 

Amish ... the post (and poster) you are asking a question about is from 2009. I think your best bet to get a direct answer from that person is through a "private message".
