finally got around to starting this project, I will keep you informed of the progress, so far much easier than my 427so weber install.

do any of you guys have the part numbers for a center bellcrank type throttle linkage, My Kirkham has one but the webers are mounted fuel inlet inward and the CAV faces them outward, also the 427 manifold is larger so the linkage is different. It looks like this.

Pat Buckley · 09-08-07, 04:49 PM

How about a linkage like this one?

I have a bracket that the cable attaches to for it.

chuck smith · 09-08-07, 05:16 PM

Pat ,I think I have that bracket.

Chuck. Thanks for the post. Are those fuel regulators you have added? I am wondering were the CAV units set to high PSI for webers?

Randy, they are the standard units and I assume are set at 5-6 psi now ,so they will need to be changed. I have no idea how to lower them, maybe someone here does.

Install a fuel pressure regulator.

chuck smith · 09-09-07, 10:17 AM

Pat, I think those are regulators mounted on the bulkhead, I do not know haw to adjust them down however.

Neal · 09-09-07, 11:56 AM

Chuck,
Holley and Aeromotive make low pressure, 2-3 psi, regulators.

Pat Buckley · 09-09-07, 07:51 PM

Chuck -

I think those are one way valves so you don't keep swapping fuel from each tank.

I could be wrong.

But I don't think so!

Chuck, I bet the CAV regs. are adjustable, I just removed the acorn nut from top of regs. and there is a adjustment screw. I have CAV 134 and am about to do what you are doing. Try backing screw off,these are diaphragm style regs,but will they go low enough?

this seems to indicate the regulator can be lowered plenty

The CAV regs I have on #29 are adjustable to 3.5 PSI, no lower. I've installed inline gauges on both sides before feeding the 48IDAs. Back out the acorn locknuts and turn the adjuster nut. They were originally set to 5 PSI to feed the Holley but the new plumbing for the Webers leaked at that setting.

ragrod · 09-12-07, 07:24 PM

Ray ,how do the webers like 3.5 psi.? I would think it would work.

I really don't think it is going to work. If you could have 2.5 or 3.5, you would be much better with 2.5. I think your float needle and seat with leak at 3.5.

thanks Rick, I found them and talked to the guy today and he set me up with the needed stuff.
