Thanks but I already ordered the other one, and the MSD distributer, should be here today.
This is all the info I have been looking for and it all makes sense. So, I need to make it all come in later, around 3000?

You'll want to change the gear on that distributor. The $2.00 gear that MSD uses is junk.

No, you need all the timing in sooner. Use a blue spring and a thin wire silver spring. I would get the bushings from FBO, and use the 10 degree one. Leave the vacuum advance disconnected until you can put in the crane adjustable unit, and install the advance stop properly, not like in the crane instructions. The cannister the MSD comes with activates and pulls in fully at too high a vacuum level for most performance engines, and adds too much advance also.

OK, I got the new distributer, now I have to set up the timing curve. Ill have to order the other bushings. So, I want it all in sooner? The distributer comes set up with heavy springs so the timing isn't all in until 5000 RPM, I know that's no good.

Re: Another cam recommendation. Hyd roller

So, if I use the light silver and the blue spring and the black bushing (18*) and set the initial at 18* that will give me 36 all in? I don't like to use much more than 18 initial because it pings under load sometimes (10.3 compression with iron heads), Where does that make it come in? On the dyno it made peak power at 34*, should I be aiming for that? Thanks, I never tried to dial in a timing curve before.

Re: Another cam recommendation. Hyd roller

I would start with the black bushing and two blue springs.
Yes it will give 36 total if you det the initial at 18.

Try to email this guy
[email protected]
He sells 10 and 14 deg bushings/10$ per piece.
If you want 18 initial and 34 total get one 14 and you can sand it smaller so it gives the 16 deg you want.

Set initial at 16, with the 18 bushing that will give 34 total. one blue and thin silver will be all in by 21-2200. 2 blue springs in by 2500. Without running vacuum advance, you want it in sooner. That will maximize efficiency at cruise speeds. The one blue and one thin silver is the quickest combination you can run without the timing bouncing around at higher rpm from my experience at least. 2 blue is not fast enough.

Re: Another cam recommendation. Hyd roller

OK guys, you all were right, I have the new distributer and the 4 speed trans in the car and the surge is gone, its a pleasure to drive again. Thanks again. I cant believe I ever put an auto trans in this car, its so much fun to drive with the 4 speed back in it. After all, if its not fun to drive there is no point in having it because I drive my cars a lot.

What spring setup, bushings, etc did you finally end up with?

Sure it will - the timing is moving in and out of full advance between those rpms. Iím sure there is no issue after it hits 2800 rpm.
Thereís nothing wrong with the distributer. Itís just set up wrong.
I'm not sure about your theory.

The vacuum advance will be all in and the only part of the advance that might be changing is the centrifugal part of the curve.

But the centrifugal part should be steady at a steady rpm.

So maybe his advance weights are screwed up and not advancing in a smooth predictable curve ?

Oops, just saw you solved the problem.

I did what "Pockets" above recommended, it runs great and no surging.
