Im swapping a s4 13b and bought a Holley carb, intake, etc with the motor. Was previously installed in a REPU.

The carb throttle bracket is on the radiator side not the firewall side like a RB prepped Holley. Before I make a mounting bracket for the throttle cable, is there one available somewhere?

this is how the cable bracket attaches. being as this is going into a 1st gen, u wont need the extension section due to the cable not being as long as it is on the fc.

Yes unfortunately that will not work since the throttle bracket is on the opposite side of the RB Holley.

 

 

I can't tell if you guys aren't reading or just trying to troll.

The RB bracket will not work for my setup.

 

Look at their post counts. They are trying to help but have no experience with a JW manifold.

Your best bet is to fabricate something.

 

It's hard to tell from the JW pic that the carb needs to be oriented backwards to that of the RB manifold.

 

The carb doesn't need to be oriented backwards on a JW. I think the OP has a weird carb.

 

Yes. JW intake/Holley Carb/RB cable bracket and LoKar throttle cable is all you need for this setup.

 

His carb is probably backwards.

 

Yes the throttle linkage is on the opposite side as the RB Holley. The JW manifold moves the carb very close to the alternator and thermostat/water neck. The hard line fuel inlet to the bowls will hit the water neck if I flip the carb to put the throttle on the firewall side.

Unfortunately I can't get a hold of the previous owner to discuss how it was installed on the REPU.

Goal is to get it driving then put Webers on ASAP

 

If the goal is to put Weber's on you might want to skip putting this Holley on. You could also move the alternator to the drivers side where the AC/PS would go.

 

get a pic of the carb u have. all the 4bbl carbs i've dealt with, whether it be stock, holley, or edelbrock, have the throttle connection on the firewall side of the carb when sitting on the intake.

 

It's backwards.

 

Here's a decent photo of one like it. Did I mention it's a 750dp and completely oversized!

Webers will come once I can verify the motor is good and burn off a set of tires. After 5 years I just want it running. I'm sure many can relate.

 

Take the carb off the manifold, and flip it around. It's backwards.

 

Consider me dense... one issue with flipping it is the hard-line for the fuel bowls hits the water neck. May be less of an ordeal than making a throttle bracket though. Thanks for continuing to beat me over the head with the obvious... it may stick eventually .

 

If the hard lines hit the water neck, they simply don't fit.

Running that carb backwards like that isn't going to run right anyways, since your primary venturi will be supplying fuel to your secondary ports...

 

Since the JW is a single plane manifold, it probably does not matter which direction the carb is oriented. Does it? Aren't all the outlet holes of the Holley the same size? I do not have one handy to check, but I am sure that someone does. Is the Racing Beat manifold also single plane? I assume so, but could very easily be wrong.

 

It isn't single plane, it's 4 hole. I made a single plane one though. Yet to test.

 

Jegs says JW manifold is single plane. It can have 4 holes and still be single plane. What does the plenum look like below the holes? If it is all one big space it is single plane. If there are two totally separate spaces (plenums actually) then it is dual plane.

 

From online pictures it looks like the RB manifold is probably dual-plane. I am just asking out of curiosity.

 

It's totally separate runners all the way down. And the JW secondary ports are massive.

 

Interesting. Thanks for the info.
