Am I blind? Where is the timing tab on the front cover for setting ignition timing?

Sometimes the spot weld that holds the factory timing tab breaks and the tab falls off. They do make bolt on tabs but without pulling the cyl head you won't know for sure it will be exactly TDC but you can get close with a straw down the spark plug hole and turning the crank by hand.

Pop the LHS valve cover off, rotate the engine until your pointer points to TDC, if both the #1 rockers are loose, you found TDC, if not, rotate again until you find that both #1 rockers are loose.

I have to say, that is stupid, that the tab just falls off, lol. It should be on the driver'* side, correct?

Or, I could pull the dist. cap off and when the rotor is pointing at the #1 wire, #1 is at TDC. Then, using an object in the #1 cylinder confirm TDC. Maybe easier than pulling the valve cover.

At least a new timing tab is cheap. What kind of labor is it going to take to put a new tab on? Does it bolt to the front cover?

Thanks.

Depending on the motor but yes 90% of the time it'* on the drivers side of the timing cover. Some of the old small blocks were directly behind the water pump straight down. As far as pulling the cap there is no need. Cylinders 1 and 6 will always be at TDC at the same time just on different strokes so for marking the damptner it doesn't matter if the dist is 180* out.

Ahh! Of course, good point!

LT1 P has no distributor therefor no tab used opti spark ignition. Y motor 5.0 olds would have marks

Come on man, had you read the rules here, you would have known not to dig up posts that are older than 6 months old. Every forum has rules on this.

It'* not an opti-spark engine, it'* a TBI engine with the small cap HEI. 75 Racer was right, it is behind the water pump, straight down. Thanks, 75.
