Graham, you can probably start at anywhere from 6-10 degree BTDC. Setting the initial timing at TDC will be a little on the late side. The motor might feel a little sluggish on the bottom end. To measure the total timing, you'll need a timing tap on your balancer, or a dial-back timing light.

The motor is running, it's at TDC right now. "Time" to break out the timing light.... HA HA HA ... Er, ok, that wasn't funny. Thanks again, -Graham. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mike Holleman Sent: Monday, March 29, 2004 8:30 AM To: The Chevelle Mailing List Subject: Re: [Chevelle-list] timing Graham, When I set timing after having the dist. out I rotate the dist as it requires to get the engine started, set static timing about where the book says, get the engine up to operating temp and then set total timing by running the engine above three grand(or what RPM is needed for total mechanical advance) and adjust to where you hope to run it. Small blocks like around 36 degrees or so, but the key is to run the car and be sure you don't spark knock under load. If you do you are too far advanced. Every engine is different. My Pontiac 421 likes 40 plus degrees. There are many people on this list that know way more than me about tuning. Maybe someone can get you closer than me, but this method will work for most street engines.

Um, well, I remember the folks who degreed in my cam wrote down what the timing is supposed to be set at ... So much before or after top dead center. I just figured that there was some collation there - and I wish I could find that paper. Oh well. So I guess the timing has be done be feel eh? -Graham. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dale McIntosh Sent: Sunday, March 28, 2004 8:49 PM To: 'The Chevelle Mailing List' Subject: RE: [Chevelle-list] timing Are you talking ignition timing?
