'66 Malibu N/SA - Page 19

Okay, the manifold is back on, and as a test I dropped in the distributor with no gasket. I measure an .026" gap between the bottom of the distributor and the manifold.

Here it is with an .030" shim and a gasket.

Hopefully it'll stay together a little longer this time.

If you don't think that gasket material will hold the distributor at the right clearance, I have seen valve spring shims used for clearance. Might have search to find one the right size but might give more peace of mind. Nice build.

Seems to me, the FelPro blue distributor base gasket seems to work as well as any for a combination gasket and spacer. The cheap gray fiber gaskets swell up and get soft after a while. Great build!! The valve spring shim is a brilliant idea. Just finding one the correct ID is the game.

If I remember we tried differential shims not sure what car but definitely was from a Chevy my partner at the time was a parts mgr so we used to shop the parts bins regularly might be worth a look otherwise depending on the ID of those spring shims they do work. FED 387

I'll measure one this weekend, but I'm thinking 12-bolt pinion shims might be a near perfect fit.

Now that I think more about it it was probably 12 bolt pinion shims you might get by with one or may have to stack them--- just remember consider tooth engagement between the cam and dist. gears--FED 387

Wow, that's a lot of ideas!

Actually, if you look back at my previous post you'll see I mentioned that I already have a shim (.030") in there, and yes it's one of these nylon shims. Seems like it should work fine.

12 bolt shim is 1.45x 2.08 diameter if it helps anyone
