The Chevy one may or may not work, manufacturer's did different things at different years. Could be possible. You'll need to establish exact TDC. Go to the knowledge base for this, there's also been alot of posts on ways to establish this. I personally liked Doc's method. Then you'll need to fasten the tab to the block day~um close.

I have a diagram for olds 350 timing tab but what year is it??? Is this engine out of the vehicle???

Chevy motors have 3 different combinations, I don't know about Olds. I think I'd get a top dead center piston stop and a degree tape and establish TDC before I trusted just any old timing tab.

As mentioned in the post by the Spector, TDC piston stop and degree tape to me is critical. I'm going to assume here that you will want to dial in your timing for your specific application later, not just turn the dizzy until the engine quits pinging!!

If you have a fax #, PM me and I'll get the diagram I have to you. If not, maybe I can scan it..............maybe

The Olds timing tab is completely different from the Chevy tab. Olds used two different types. The 1960s and 70s motors have a stamped steel tab, the 1980s motors used a plastic one. I don't know if they interchange or not, but I'm willing to bet they do. The tab is retained with the two bottom driver's side bolts on the front cover. The tab from any Olds V8 (455, 330, 400, etc) will work.

I have a 1977 olds Cutlass that has a 350 rocket motor or what most people I know call it a 355? anyways I set the timing the way I was taught on a 350 chevy. Bring the #1 piston up to top dead center. Mark the dizzy to the post on the dizzy cap for the #1 plug then put the wires in this order 18436572 it should run fine.. Mine does maybe I got lucky

hope this helps

Ed

You are exactly correct Joe. Olds 350, 400, & 455 all the same. This tab also looks identical to my '71 Chev 350 tab. Don't know if it's exact but looks awfully close.. Interchangeable???

Maybe get the Chevy one from the parts house and compare it next to one in a wrecking yard??

Again, the Chevy tab will not work. The Olds tab picks up the two lower timing cover bolts on the drivers side as well as the dowel pin. Chevy motors are different in this area.

I was thinking that I bought a chrome tab that bolted with the timeing cover bolts to the block and it had a third hole for the alignment pin.....its on a motor at the house. I'll check tonight and get back to you.

Also make sure that someone hasnt put a aftermarket balancer on it measure it around the outside of the balancer.....its concevable that it had a 6.5" on it and someone put a 7" in place of it...and cut the tab off

That's all good advice, but trust me, you just CAN'T buy that stuff for an Olds motor. You Chevy people are spoiled...

Universal timing tab= short piece of stainless steel wire , available at your hardware store. Put a loop in one end, bend to fit your timing mark 0 at top dead center. Bolt to timing cover and your good t go and it don't cost squat.
