I didn't read all the other comments but to me, it looked like you did pretty dad gum good for a first time out!!!
And if you want to go faster. I'd start with tuning, tuning, tuning. There is always at least a couple of tenths there.

Wow....I've done gear changes lots of times without making other changes to the stock engine and always saw a change in ET's.And back in the day with a stockish cam (you have more cam for sure) we tested 3.23 to 4.10 with no other changes on a fully laden 69 charger and it made absolutely no difference.
Typical Holley, intake, and headers.
In my day the guys with 3.23 gear were usually quicker that the 3.55 or 3.91 guys. The 3.23. were rapped up in second gear and the 3.91 guys were lugging along in third for the last half of the quarter. Now 4.56 word well, but then you needed slicks.... This was my experience..In my 67 street 383 charger, with 323s I'd go 6500 in 2 gears at 13.70-80
With 456 , 6500 in 3 gears at 13.19.
BUT, it's a different political and climate environment up here. We also have French as a second language.

That was my experience too. I had 3:23 stock in my GTX, but I thought I could do better with 3:91’s. Nope, actually slowed down by a couple tenths.In my day the guys with 3.23 gear were usually quicker that the 3.55 or 3.91 guys.

My first car did that with a 383 and 2.94 gears....ran a 14.80 with those but did pretty much the same thing with 3.91's on street tires. Crossed the stripe in top of 2nd with the 2.94's but ran through almost in the top of 3rd with the 3.91's. Think I was losing traction off the line and shifting into 2nd. Sometimes the loose of traction isn't enough to feel it but it's enough to scrub off ET. Also didn't have an LSD in it....That was my experience too.

Well worded. A 440 is a grain truck engine, a 340/383 is a race engine.A 340 or warmed up 318, gears will make a good difference, you need to twist the rpm hard.
A 440 with stockish heads, rpms are not your friend.
383/400 with the stock stroke and basically same head as 440 the rpm range will go up, again gears will not hurt. These short stroke combos are the heavy car smallish engine mentioned before.
I agree with whoever said earlier that I would spend the money porting the heads not a gear change.
Or just enjoy for a while.
