Am installing stock 302. Put on an iron 4bbl manifold (C8AE) and Holley 8007 carb. A spacer would help keep the control cables and fuel line off the manifold.
I read about the performance qualities in the archive section.
They don't look that complicated, and I saw where some have been made of plywood. I have plenty of scrap 3/4 inch birch (cabinet grade) plywood and access to a lot of tools.
Is this practical? Or is it one of billy-bob's-off-the-wall-ideas to save money? Just need to raise the carburetor an inch or so. Don't want anthing that will leak or catch fire.

 

I don't like the idea of wood because it can absorb fuel over time and become flamible, but, I've seen them used at local drag strip a lot and no one ever had a problem.

 

A 1" 4-hole aluminum spacer is available at AutoZone or any parts house, they don't cost a whole lot and come with gaskets and longer studs.

 

DONT DO IT !

 

Thanks for the replies. I'll get a phenolic one. Did sound like bit of a fire hazzard.

P.S. Has anyone ever used an old water heater tank to store compressed air? They work great......untill they EXPLODE.

 

The wood spacers have a performance advantage, but must be replaced regularly because they do absorb fuel. If your going stock, best stick with an aftermarket piece. Get a 4 hole, this will give better low end torque. The open ones seem to boost higher rpm horsepower.
If you want to get real crazy, you could make a bunch of spacers out of wood and see which one works best with your combo, they buy the plastic one.

 

They make them out of plastic and phenolic, plastic is cheaper to do your testing but use phenolic as the final spacer as it is stable vs plastic crushing down over time and heat.
