My 327 has adjustable lifters so I'm presuming they are mechanical. The service manual says the adjustment should be made with the engine fully warmed up. My question is what should I set them to initially?

On a side note, the manual talks about the 200 & 300 engine. Is the '300' engine the 327?

Thanks,
Joe

I usually do 9 on the intakes and 15 on the exhaust when cold. The manual was written for the 51s so the 300 meant a 327 with 5 mains, though they had hydraulic lifters.

Ross, thanks.

Mine's a 327 with 5 mains, should it have hydraulic lifters?

Also do you have a head water outlet (5.0508) and associated parts?

Thanks,
Joe

Joe, how did you make this determination?

see attached photo
I can adjust them with a couple of 1/2" wrenches.

I set mine hot then checked them cold to see the difference. There wasn't any.

Thanks for the help. Guess I set them to start as Ross suggested to be safe, then do the finals after it's running.

Good advice from Ross for a proper and accurate method for valve adjustment. Here is a different method that I prefer as I dislike trying to adjust the valves with the engine running and being close to all the heat and noise. The center cylinders are particularly hard to adjust with the engine running.

I run the engine up to operating temperature after preparing the car for valve adjustment including removing the tappet covers. Then, with the engine warmed-up and shut-off I adjust the valves, one cylinder at a time to the hot setting. I usually adjust one-half of the valves then run the engine again to restore operating temperature and finish the job.

Perhaps I like this method because I do it so infrequently. Those, like Ross, who do valve adjustments on a regular basis get adept at working the wrenches and feeler gauges with a running engine and can do the job quicker than the way I have described.

I like to use go and no-go feeler gauges rather than the one thickness type.
