I just came in from about a 30 minute drive. I laid down about a 20 foot mark on the pavement!


Jeez I would have liked to have been there . You sound pumped! With no vac adv I think you can go with a bit more than 35 maybe 38 but for now I would retract it to 35 (you can continue to experiment later) and yes on the springs you want it to advance in a linear (straight line) fashion with no elongated slots or 2 stage etc. (1) get the initial where you want it (2) set the screws for 35 total (3) get the non slot/non stage springs in there that keep it just under the pinging point at WOT up thru the gears and that your spring choice does not start advancing any lower than 200 RPM above your in gear idle speed. You can use mr gasket or MP or even chebby springs in any combo to get the rate you are after but keeping the OE light spring on the one side is a good start




Once the motor has cooled a bit I think I am going to try an orange and a pink spring. I will drop the advance back down to 35 all in and see how she does. I am pretty excited at this point. I am seeing some positive improvement. Hey, it's my birthday too! I got to do a burnout on my birthday! Might even go for two!

Not insulted at all... I appreciate the heads up...Of course I will probably still call it valve chatter. Old habits are hard to break. Plus it sounds like the valves are chattering to me. Just sayin...

At least 2. EDIT I just read thru the instructions for the mallory system that challenger1 provided as I've never owned or worked on one & it mentioned that some of their springs might be a little too long (by design for their system) & will likely let the timing flutter if the wrong combo is used and they mentioned that their tabs can be bent (within reason). Bottom line you want no slack at your idle speed.

The slack is in the purple spring. Thats why it does the two stage with that spring combined with another non purple spring. The purple spring only engages once the advance reaches a certain point and slows it down as it goes all in. There's not really slack at idle. The non purple spring is holding the advance. It's just that the advance goes quick until the purple spring gets tension and slows it down. Listen to me...I sound like I know what i'm talking about!

I swapped out the purple spring to another pink. It now has two pink springs and goes all in fast. I closed the slots a bit so that I get about 38 degrees all in. I have it set at 22 degrees initial. I took it up the road for a quick ride and it is definitely better. I think swapping the spring made the biggest difference yet.

Oh OK I see what you are saying, there is no slack in the system cuz even tho the purple has slack at idle the other spring is taut & there's no (overall) slop. I would want what you did & that's light springs with no slop in either of em. Sounds like you ended up with one hell of a birthday

You may not get the engine to knock at 40 degrees total, but it should make more power at 34 - 36 degrees total.
The more advance you run, the more negative work is done on the piston, expanding gas pushing on the piston as it comes up. More modern combustion chambers are running 28 to 32 degrees total for max power. LA Mopars typically use 34 - 36, big blocks need 38. Mag heads if set up properly use low 30s.

The best way to tell this is to use the quarter mile dyno, the fastest mph is the max power setting.

Back in the day, the hot 340s on the street all ran 3.91s.

I got home a little early from work today. I took the car out for a drive. It was the first significant drive since I did the last changes on the distributor springs. I had also readjusted my rockers to solve a ticking issue. I was on a country road and stopped at a stop sign. There wasn't anything or anyone around so I stomped on it. I laid down a double strip of rubber at least 40 feet long! I actually fishtailed a bit. Keep in mind a week ago I could barely get the rear wheels to spin with the brakes held down. I absolutely roasted the tires with no brake usage. I haven't even installed the new torque converter yet!!

I'd double check the TDC mark. It sounds like it might be off a bit if you are running 40-42 total. I sent you a PM on a gear.


I want my fair share

I got the new torque converter installed today. I just finished up a bit ago. It was too late to take it out. I will fill it up with trans fluid in the morning and give her a spin. I can't wait!

All I can say is Wow! I had no idea how much difference a good torque converter could make. Between the lower transmission gears, the fine tuning on the distributor and the torque converter my car is now officially a beast! It's almost scary now. I hammered it and it would not stop spinning! It spun all the way into second gear! I even punched it once when I was moving about 15 mph and it lit up the tires! I just came back from about a 45 minute ride. I now have about half the tire tread that I started with.

I can't think everyone enough for all of the advice. I need to send an extra shout out to RapidRobert for all of his help. You guys are the greatest.

I wish you guys could have seen the ear to ear smile on my face when I was roasting the tires!



I have my sights set on a set of 3:55 gears. I can't wait to see how that does.

Congrats.
One thing is for sure, these cars need to be dialled in but once they are it is amazing how well they can work.

Congrats on your success!

Personally, I would not waste my time going to a 3.55 from a 3.23. The actual return will be very small.
