Mild 440, iron heads, a 509 and 3.23 gears running 11.97..... sounds like it's working pretty good to me. 
Obviously I need to get my act together, mine should have a ton more in it........... 
I agree you have a nice low RPM that will last forever. Consider yourself lucky.

More gear for sure. I think your rpm limitation may be fuel, and/or the ehads. I only say that since they are "stock" iron heads. Are they unported? On the whole, I agree with the comments that the results aren't bad given the mild nature of the combo.

the reason your engine runs the fastest et shifting there is because you were smart enough to try it
a very old racer in charleston by the name of Art Windom would jump into someones 440 powered car, shift between 5000-5500 and always run a new best in the car. aarlucas will back this up if he happens to read it. he knows Art well

 I'ld also say that's really good for what you have.
Throw some head work and gear at it and

Need's more gear to pick up the ET. Don't think you need more fuel at 115, that's pretty good. Started out years ago with a similar engine, sounded great shifting at 6000, but always ET'd better shifting at 5500!

Upping the static compression wouldnt hurt either. Thats a decent sized cam for medium to low static and a tunnel ram.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

ALL you need is a converter swap and it'll go mid 11's (your 115 trap speed is enough to go 11.50's).......... with the gear you're running right now....... When the converter is right, gear ratio has VERY LITTLE effect on ET........ Call someone like PTC and get something that'll stall in the 4,000 to 4,200 range and you'll be there...........

I agree with this to an extent. I think (my personal opinion) is more conv will be too much for the gear.
On a second note, you don't need more gear if it doesn't like the rpm's, if you have tried more.
600's may help or may not at 5200 rpm. I would let that sucker alone and run the pi$$ out of it and have tons of fun.
BTW it runs very well compared to most.

75-125 hp of spray hidden under that ram, shift that baby at 4500-4600 and go looking for some easy money. But you may need the 600's then.
AND DO NOT SHOW ANY PICS ON THE WEB IF YOU HAVE ANY PLANS OF DOING THIS!
Good luck

I have a stock shortblock 440 with .030 overbore 9:3-1 compression with a 509 cam, Stock steel open chamber heads and a tunnel ram with two holley 450's
10 inch 3500 converter and 3:23 gears
3380 pd with me in it 70 4 door valiant
I took it out the first time to the PRP chrysler classic it ran a best of 11.97 @ 115mph
It would ET best shifting at 5200. Why is this?
I do know the jetting was lean as the plugs were real white (but no popping) the carbs have metering blocks in the back w 61-69 jetting and a 4.5lb powervalve. Timing ran best at 35 degrees
Has anyone ran a similar combo w tunnel ram and 450's and when I jet it up should I keep the same incrament between the front and the rear?
Do you guys think it will pick up with 600's
I would like it to run mid 11's
your 9.3:1 w/ a 509 probably nets you a 8.5:1
3.23 gears w/ a 509??? you need at least 3.91's
With that compression you could probaly try 38* total and be fine.
Are you springs ok for a 509? you might be getting float at 5200+ if you have weak springs.
Also T-Rams are cool but a good single 4 bbl intake w/ a 850DP would probably run stronger.
I address the gear and timing 1st. W/ 3.23's I'm suprised you broke 12.0

I hear that a LOT, but I've done it so many times I can't count...... I've got 3,900LB cars running around with 4K converters and 2.76 gears and they work GREAT........ 
Quote:

That's another reason why I recommended the converter, instead of a lower gear........
Two 600's is more CFM than that motor can use, so I'd keep what's there for throttle response and tuneability.........
For an example, the car below runs 10.70's @ 124 with a pump gas, stock stroke, 440 with 3.55's and a 4K converter......so it's ETing real close to where it should according to the MPH.......
