carburetor spacer

[MrFreeze]

So I fit the 4100 carb on the stock 1" spacer on top of an Edelbrock Performer RPM intake, and it looks like it will be too tall for my stock hood. In addition, the stock aluminum spacer is wider than the top of the intake, and it looks real questionable about whether or not it would even seal up. I had heard that might be an issue, and wasn't too surprised.

Can I use one of those thin (3/8"-ish) phenolic spacers to make this work? Will it seal the 4100 carb to the Edelbrock intake? Anybody have a suggestion for me?

Thanks,
MrFreeze

Hello Freeze

I have a 1/2 in spacer on my edelbrock performer with edelbrock carb. Lots of clearance.

I did switch to the Hi-Po air cleaner. It has a recessed base and sits about 1in lower than the flat air cleaner that I had in the first place.

I believe the RPM is taller, but with the Hi-Po air cleaner it should fit.

I placed a big ball of plumbers putty on top of the air cleaner and closed and opened the hood a little at a time to check the clearance.

Just get a generic 1/2" spacer with a PCV nipple and Holley flange. Make sure you use a gasket on each side with an appropriate sealer if it looks questionable.

how about a drop base air cleaner? I am having the same issue but I have not got around to measuring how much drop i need. I have an edelbrock rpm intake and an edlebrock 600cfm carb and with the air cleaner I have lying here there is no way my hood will close.

Most likely you will need a plate to protect again vacuum leaks with the Autolite base on that intake setup...

Edelbrock #2732 "sealing plate" :


and a carb. spacer with a PCV input like Barl notes... Unless of course your running a road draft tube out of the passenger valve cover

Why get a drop base when you can get this!?

I used a gasket, this spacer then another gasket and then a stock pcv spacer another gasket and then the carb, summit sells em cheap and they work well.

I found out the hard way that my edelbrock 500 on top of a 1 inch spacer on a performer 289 will interfere with the hood. Add a 1/4 divot to my hood to the "body work " list...

I used the thin Boss carb spacer with the pcv tube on my RPM Performer manifold to seal the carb and for hood clearance with an Autolite 4100 carb.

As long as the gaskets are fully sandwiched between the carb/spacer and spacer/manifold then you should have a good seal.

Good point... With most aftermarket aluminum intakes the plate is going to be used below a stock Ford spacer (since spacer is designed for the Autolite), or in most cases above an aftermarket spacer due to the size of the Autolite. One way or the other depending on spacer used...

i'm bringing this one back since I have this issue. I have an edelbrock RPM intkae, 1"inch spacer and edlebrock carb. I tried a drop base but the one I bought did not clear my electric choke or my linkage.
