I installed my new ignition conversion today. Started right up and idles smoothly. I was advised to check the timing at idle, and make sure it was at 6 degrees BTDC (as it states in the manual). I didn't have enough daylight to do it today but I noticed that there is a "pointer" but no scale? Am I missing something? Thanks in advance!

If your motor is a 351W Ford based engine, you have a pointer that extends outward from the timing cover and the "scale" you speak of should be on the outer ring of the harmonic dampener (mounted to the end of the crankshaft). It should have a "0" (zero) and some marks with other numbers such as 10, 20 and so on.

sometimes the timing marks get covered up with dirt, so take some carb cleaner and clean the edge of the balancer and you can use a piece of chalk and rub over the grooves/timing marks so you can see them easier.

Yes, Ford 351. Should have mentioned that in the first post. I'll clean that balancer up and see what I find. I guess I've usually seen the mark on the balancer and the scale fixed on the block. Thanks again.

To make the marks easier to read, my method is to use correct fluid (i.e. liquid paper) and "paint" the line I want to use for base timing and then another a set distance from base. This way you can estimate settings in between the two marks.

If you cannot see the timing marks check to make sure you have your light connected to #1 cylinder. Ford's are different than GMs.

Well, too rushed to put the light on it, but went out Saturday for a test run. Ran beautiful; idle, cruise and fairly high rpms. Lake was too rough to run WOT. The new prop makes an astounding difference. I'm assuming that the timing is close because it runs so freaking good. I wish we had more time to spend on the boat.....

Go to a speed shop, buy a timing tape glue it on to get accurate reading. However the right way is to degree the cam find dead center or use a plug to be sure where the real dead center is. With hrs of runing the chain streeches and dead center changes
Also the orginal chain and sprocket are built in retardeds 9 degrees from the factory. Replace with the over the counter chain and sprocket and gain more power.
