Different take on ls fuel rail.

[andrewb70]

Andrew,

If you run the factory intake and rail, you will be fine. Are you looking to change the setup?

I am using a Holley Hi-Ram intake with the Holley fuel rails.

This is what the dampers look like in a 03 truck fuel rail.. Hay Bill these are to wide to fit inside my 1/2 inch copper pipe. Do you think it would be ok to shave down the sides till it fits or could I use a flat peace of stainless that will fit.

Andrew,I think there is enough field experience with the Holley set up to indicate that you will be just fine.

Those are made by Delphi and are not the same as the Corvette parts. The Corvette parts that Bosch made do not have the flange.If you trim the flange, the dampers will have a shortened life. I would definitely not recommend it.Maybe you can find an old Corvette rail to steal the dampers from if you want some. It needs to be one of the later silver stainless rails. The old LS1/LS6 rails were black and had a regulator or diaphragm damper on the crossover.

Bill,
Do you think thier will be as much pulsation of the fuel since I am feeding from the ends of my rails and dont have the cross over in the middle?

Kevin,

Actually the crossover in the middle can be an advantage. The biggest magnitude of the pulsations is normally at the ends, not the middle.

However, there are other factors such as fuel volume that help. The more volume in the system, the less of a concern pulsations are.

There is a trick that works quite well, but does not always package on some engines. If you feed both sides from the back with a "Y" and then make a crossover in the front, it gets rid of the harmonic pulsations that cause fuel delivery issues. It works surprisingly well.

So if I do a cross over in the front, (in red) I most likly wont have an problem?

What are the internal dampers made of? Assuming stainless steel, it looks like you are right at the edge of having some galvanic corrosion issues.

I would also take a look at the material in the injector clips. You could likely have them copper plated.

Yup. That is correct.

They are made of stainless steel as are the retaining clips.

wood overlay on the ls manifold... and custom cut some brass valve covers with inlays of wood.

Hydrodip with wood print.

I agree with the above post. It could be one very cool retro engine.

Ill look into it. Might be a little to much for the car its going in, but maybe it will start a theme. Its only a 86 cutlass.

[Mr Nick]

What do you mean 'only' an 86 Cutlass?

That was my first car, and I've been an Olds guy ever since! I'm a bit biased.

Sweet looking set you you're making though, that's what makes a car stand out from the crowd, different little details.

[williecutlass]

I have had mine for about 18 years now. Was my first car.

[williecutlass]

Well I got the cross over done along the front and got the throttle bracket and throttle body adaptor fabed up and powder coated.
Might look into making some bambo coil covers
