Ok so did some searching around here to look at different timing marks on pulley and couldnt find one like mine sorry for poor pic image  :
so question is the dent is TDC to the left of it is a notch and to the right of the dent are four notches (white erase marks are four notches) that my pulley has what are they or how should i time my car?
Im running 34pic3 carb 009 distributor and my car 68' struggles on hard acceleration as in when i floor it it stumbles bad

Those are home made marks.

Do the "pencil test" on cylinder #1 to find TDC (top dead center). Then you will know for certain where TDC is and can go from there.

Or you can pull your distributer cap off along with your valve covers to check that way. Also while their off, check your valve clearance...
good video on how to do this--->

But read abut all the a-holes that dropped it in before.
Remove the crank pulley and the keyway is at 9:00 when it's at TDC.

Glenn's photo rotated to show notch at 9 o'clock position and TDC at top. Remember, this could be TDC for either #1 or #3, look at the valves or the distributor rotor position to be sure.
And don't use a pencil; if you feel you need to do something like that, use a plastic drinking straw.

bingo... can't tell you how many times over the years I've suggested a drinking straw to someone only to later read their thread on "how do i get a broken pencil out of my cylinder".....
I use a positive stop, myself...

I didn't drop a pencil in the cylinder, but it did break off as I was trying to slowly cycle the engine to get it to TDC. I was however a good excuse to do a teardown and rering the cylinders and freshen up the engine  |

haha...the key is to hold the pencil so it comes up straight... the pencil has a tendancy to drop to the bottom edge of the cylinder... damn gravity.... this puts the pencil in a bind as the piston comes up....

This pic shows you that the stock timing marks are along the front (front of car) edge of the pully.
Also, if your distributor and pulley have not been kept as a matched set, the timing mark on the pulley may not be correct for the distributor you have installed.... lots can happen over the decades since our cars have left the factory.

That works when you are familiar with the motor and KNOW that the distributor drive gear is indexed correctly. But if you are unfamiliar with the motor, I'm not sure you should trust that the rotor will point to the mark on the distributor body rim when the cam/crank is set for TDC on #1. Also different distributors point to different posts for #1 cylinder. And the installation of an electronic point module can change where #1 fires.

Or if the engine was rebuild and the builder installed the driveshaft 180 off and then just moved the wires to accommodate it.
Never ASSume.

the real key is to leave the Muir manual in the shithouse and the Bentley in the shop...people seem to gravitate to Muirs worst proceedures..hell I gotta pencil in the shop,I use it to write shit down,crank position and valve position is the only way to tell TDC 1,on compression. |

I like the Muir for just reading for enjoyment. Like a comic book. But since I just got my Bentley recently..."wow", thats like having a vw mechanic in the garage with me.

I gotta be honest johnny.... I've never read Muir, and I don't even think I've ever had a copy in my hand... the pencil idea wasn't Muir's, its been around longer than muir...in a standard V8 or I4's and I6's, it's a viable indicator of when the piston is at TDC... I agree that valve position varification is the only way to know if you are on TDC on compression or exhaust.... that said, I pointed out earlier that I never suggest someone stick a pencil in their plug hole, if they need the visual(since pullies seem to vary) then use a drinking straw... I use a positive stop to check all my pullies(aftermarket) for accuracy, not a straw or pencil...

Why not just go by the pulley. Have any of you ever had a stock pulley that was made with the TDC mark or the keyway in the wrong place? How about an aftermarket? I guess Ive never heard of it.
