L-36 ignition shielding brackets

Re: L-36 ignition shielding brackets

Here is a theory why 68 and later BB had orange supports for the shielding.
In 68 the shielding box profile changed to a simpler design. The valve covers also went to chrome from orange. If ALL BB had the shielding (even non radio cars) to "dress the engine" then it may have been more advantageous to install the brackets at Tonawanda and thus they were painted with the engine.
If someone has an AIM for 1968, they might look up the shielding and brackets to see if they indeed have a Bill of Material part number which usually indicates "installed on the assy line in St Louis"......

Also the intermediate rear ignition bracket, welded on a 67 valve cover, was eliminated in 68 which probably required the orange bracket to support the wires in the 4 hole rubber grommet as shown on the example photos above....

The attached photos are of a 67 BB showing the welded bracket on the valve cover

But what do I know... I didn't stay at the Holiday Inn last night!!

Re: L-36 ignition shielding brackets

Stephen, thanks for the effort to find out. I have a 3937793 on my Jan build 68 now(going to assume it was replaced under warranty early in its life) and am looking for 3919849 so wanted to make sure everything was right when I install it. From what I've learned here I'm just going to paint the supports orange individually. Thanks again!

Edward, funny you should mention that engine George has for sale. I have that for sale thread in my favorites menu and have been using the pics for awhile now for reference although I suspect that engine has had some paint touch-up done to it.

Thank you everyone for your input.

Re: L-36 ignition shielding brackets

Terry et al, George (1960fi) was selling a late 1968 L36 engine on the other forum for awhile and it appeared to be very original. HERE'S THE LINK.

As you can see, the supports are orange.

I do see the orange supports but the rest of the engine paint job was not done at Tonawanda, so all we can hope for is whoever painted the engine repainted what was originally orange. It is hard to see much of the distributor shield supports either, so there is no way to tell from those pictures if they were spray painted or brush painted.
