At what point (rpm) do you want all the timing in?, and what is a good total timing number to set up the dizzy at?

Thanks for the info!!!!

I am not sure how altitude affects timing, but looking at you sig I would start at 20 or more initial and 35 total by 2500.

I agree. I'd start with the numbers above.

Of course, timing will change with each engine/combo. Having said that. 20* initial is WAY too much in most cases, and usually you don't want full advance before 3000RPM. A lot of people will suggest to wait until 3500RPM for full advance just to be safe.

i agree that all in by 3k is pushing things a bit. i used to like all in by 2500, but the lighter fluid we use as fuel today wont handle it.

302ci + 244*@.050 + Vic JR + 5000' elevation = a lot of initial. Idle and throttle response will improve a ton with a lot of initial. You will see.

So do you want all of your timing in, by the time that your cam and manifold wake up, and start making power

I am no expert but I do follow a lot of what this guy says at Bad Ass Racing Engines. He has a HUGE tech tip section with all kinds of subjects. I put a link to that page and another link to one on timing. I am not sure if what he says applies to you guys, but it seems to be good info anyway.

Link to his tech page: General Engine Tech Tips

Link to the article about timing: Where should I set the timing on my performance engine?

I learn a lot from this guy. I can't use half of what he says though because my car isn't even CLOSE to being a performance car. Mine's just a daily driver.
