Ok I've read a bunch of articles on installing a distributor.......

Half of them say get the motor to O TDC and get the rotor pointing directly at the #1 post on the cap..... the other half say set it at 8-10 BTDC and then get the rotor to point directly at the #1 post on the cap .........

Its an MSD Pro-billet and my motor builder suggested I start out with the black bushing and light silver and light blue springs......he said about 38 degress would be a good place to start....

I set it to zero, but 8-10 advanced would work! You just want to get that new motor fired with minimal cranking!

38 degrees of total timing? Mine has 12-13 initial and 20 mechanical for a total of 32-33.

38 degrees of total timing sounded really high to me too.....

For right now my objective is to get the motor running, broken in and at least driveable. I'll worry about optimal HP/TQ tuning etc later. I have a friend of a friend that does dyno tuning, so I'll worry about that stuff then.

I am not the guru on how much total timing an engine should have, but here are lots of other guys on the board that could tell you.

I am sure others will give advice some good some great. My input, based on just doing it recently, was to set it at 0 degress, point the rotor at or close to number one, hopefully you are on the compression stroke of #1, and crank it over. Once it starts then start your final tuning. I like to set mine for 35 degrees (SBC ZZ3 350) and let the initial fall to around 12 to 14. Again it is pretty much upto you on how you tune the car and its application. Good luck!

without knowing more about your engine/combo. I would say to shoot for 34* total that should get you in the ball park. 38* seems a little high to me. This won't be an issue until you get the car running , cam broke in, etc... If you have access to a dyno then I would tune for what gives the best results.

I am with Paul on the initial timing, just set it to zero and fire it up, you can fiddle with it as you break in the cam (to smooth it out a little). Once the cam is broken in you will have plenty of tuning hours ahead of you.

If you turn on the ign,
set the engine about wehre you want the spark
then
rotate the dist it will spark even when turned slowly
a timing light makes it easy to see the spark or you can hear it
tighten the hold down and it will start

I think it is much easier to get it close
Good luck

If you are talking about a 327, I wouldn't be scared of 38 degrees, unless you hear it pinging.
