305 timing cover

I bought this 92 Camaro, 305 TBI, that some idiot has played with. They have installed a cam, and did not know how to set timing.

I can see why, their aftermarket timing cover has no timing tab.

Correct me if I am wrong, but the stock 92 305 cover has the timing tab at 12 o'clock, right?

And where can a guy find a factory style cover for these engines? All of my options are turning up generic covers with the tab in the 2 o'clock position.

I believe you’re right on the orientation of the pointer. Put a ad in the classifieds wanted section or look at the junk yard. A tbi truck might have the same cover.

Junkyard item.

Any car or truck with a SBC that has a similar PS pump arrangement will have the 12:00ish timing tab. It started in the late 70s. The PS pump relocation caused by the front-steer linkage, which moved the gear up right next to the front of the engine which in turn force them to put the PS pump in a different place from before, is why they changed the tab location.

Doesn't have to be one of these cars, or TBI, or a 305. Any of em will do.

Awesome info guys. I'll check my local yard and if not I'll snag that ebay cover.

Re: 305 timing cover

You could also go to an aftermarket balancer, and associated timing pointer. The factory one may have poor rubber in it by now anyway. I think I paid about $50 for a new balancer and not much for a new cover and a pointer for it.
