Clamps for Fenton intake

[Robin (UK)]

Guys,

Does anyone have any idea where i can get a set of four offset clamps for fitting the Fenton dual-carb intake?

I believe the Chevy stovebolt uses something similar.

Thanks.

Robin I have a Fenton, not using anything special for fastening it. what clamps are you refering to????

[Robin (UK)]

The intake has flanges which need to be clamped to hold the intake in place, but the flanges on the headers are thicker, so it won't clamp down.

I've been told that Chevys use 'bridges' on the bolts, to hold the intake.

Robin, do you mean the fat washers that fit over the studs and hold both the intake and exhaust manifolds on?

I had the opposite problem, my intake flanges were thicker than my exhaust flanges. I ended up using a Dremel to cut "eyebrow" reliefs into the intake. I have heard that there are such washers that are machined to be thicker over 1/2 the radius but never found a source.

The fenton and the stock exhaust manifold have not presented those problems on my application, bolted up just fine. You might look a t body washers and see if you can modify them for your needs. the are about the size of an American 50 cent piece.

You need to fit the headers,, ground down (file works great too), the high spots on whatever manifold that is high, to get a even fit for equal pressure to both intake and exhaust.

Guys ,

Thanks for all the info, on and off the Forum.

As usual - you are such a great source of knowledge.

I have to confess that my intake is a Sharp unit (not Fenton) but I knew a lot of you run Fentons so I was trying to tap into your knowledge.

It seems that the intake has thinner flanges than the Fenton headers, so it's not possible to clamp the parts with the standard clamping washer.

The guys at the shop are now going to machine a set of stepped washers, so that the hold-down pressure is correct on each piece.

They are hot-rodders, so they’re used to solving those awkward little problems.

And it’s good to know my car’s in safe hands.

Thanks again.

Have a good weekend.

Robin.

Robin, make sure when they do the install they do not over tighten those manifold fasteners. they should only be about 15 to 20 lb ft. (guess you'll have to do the conversion to newton meters.) The manifolds need to be able to move a bit through engine heat cycles.

Interesting that you have a Sharp intake, I have heard they are quite scarce. I have seen only one on a car and only a couple on Ebay.

Good luck with your enhancement.
