Hi All,

I went to install a romac 0224 balancer on my '71 slant the other day and it appears the timing marks are way off. Has anyone had this issue before? As I understood all the slant balancers are interchangeable but I knew this could be an issue with the timing marks.

I'm not keen on making my own marks on the balancer considering the cost of the piece.

Anyone know of a part number that would fit up to my '71 and zero out to the stock timing indicator at TDC?

You might look up a bolt on Factory early timing tab.

Yes, you need the early bolt-on timing tab.

My Google skills are failing me, can either of you point me to the tab I need?

Thanks All!

It's a "go fish" used item you're after. Post a parts-wanted ad.

Okay, I have one that is spot welded on right now.

However, one more thing that that is throwing me off is that even with a different timing tab I'm not sure how close i'll get. the pully is reading about 270 degrees near the stock timing tab. I would have to rotate it almost 100 degrees to get it close to my tabs, zero.

Will the bolt on tab correct that issue? Do I need a whole new timing cover?

Did I find TDC correctly? I have #1 at TDC, both valves closed, and #6 has both valves open. That's correct, right?

Anyhow - I'll try and get some pictures later to help clear it up...

Is this what you guys are talking about?

Wrong. It sounds like you haven't found the correct TDC.

At the correct TDC on #1, both valves on #1 will be closed and both valves on #6 will be closed. The rockers on #1 should be loose since the lifters should be completely off the cam lobes (compression stroke), but the rockers on #6 should be tight since the lifters are riding the end of the exhaust lobe and the beginning of the intake lobe on the cam.

To find the correct TDC, remove the valve cover and trunk the crank by hand while watching the valve on the #1 cylinder. Turn the crank clockwise until the #1 intake valve opens and closes. When the #1 intake closes, the #1 cylinder is on the compression stroke. If you continue to turn the crank clockwise after the #1 intake closes, the first timing mark that lines up to 0 on the timing tab after the #1 intake valve closes will be the correct timing mark. Once the intake closes, the timing mark shouldn't be more than about 160 degrees away from the timing tab. If you have to turn the crank more than 180 degrees after the #1 intake closes in order to have the timing mark line up, then something isn't right.

No good. And the one you show in the picture is a '78-up indicator. The one you need is held on by one of the timing cover bolts, and is on the manifold side of the engine.
