before you swap alt,get one of the newer solid state elect voltage regulators to replace the old points type you have with the round back alt with one feild wire
this will help the dim lights at idle and works way better than the points style VR
best 12$ upgrade I did to the 68Dart I had 
you can run a square back alt by grounding the 2nd feild wire and hook the other up for an up grade, the one from the truck should bolt right in place of yours
you can use an external regulater denso 120 amp(late 80s cars/trucks/vans) on stock non a/c pullys,has the double grooved belt pully on it and works on the stock external VR for a good upgrade
i have one on my 440 in the sig pic on stock brackets,you just crimp on eyeloops for the 2 feild wires and bolt it on
IMHO,I would do the 12$ replacement VR first and see if that fixes it enuff for you,before changing the stock alt for another
x2 on a timeing light and vac gauge to start tuneing on the carb,all 3 work together to dial it in
good luck
Thanks..what year regulator would I need? Anything above say a '71??

If you're going to try and tune the carb, don't forget the step-up springs. They can make a big difference in how lean/rich it runs.
This is probably the biggest oversight by many. It's the equivalent of the Holley powervalve.
I ran a 750 Comp. Series Carter for 14 years on two different cars. A great street/strip carb that is fuel efficient too.
The metering rod plungers would occasionally seize in their bores and it would idle rich but other than that never had to do anything after tuning other than change a needle/seat one time. Jets are easy to change, no fuel spill, metering rods change in seconds. Pump squirt selection and adjustment is limited though.
Good for mild-to-warm street driver, street/strip cars.
My 69 RR got 14 mpg and ran 13.70's at 103 mph on street tires with a 383, single-plane, 284/484 MP cam, headers, 4 speed, 3.91, 28" tire.

To the best of my knowledge. This both backwards and innaccurate. The 1407 is a manual choke version that is set up a little richer out of the box. The 1411 has an electric choke and is set up a little leaner. Niether is "Permanantly" leaned out. The jets, rods, and springs can be set up in either carb however you like.
Backwards, yes. Sorry about that...lol
I referenced the website and read the picture wrong.
But, in terms of the leaner... I had both to look at and the "leaner" is not metering rods and jets, but the emulsion bleeds and non-tunable passages that make them leaner. The reason they say not to use them on higher performance engines (well, with RPM or Torker II intakes) is because you can't simply swop rods, jets, or springs and properly richen the entire system. They come with leaner tuning parts in them to work with the other non-adjustable circuits that are calibrated leaner.
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.

Quote, Thanks..what year regulator would I need? Anything above say a '71?? Nope it is a direct replacement for the regulator you have. It is just electronic instead of points, there fore more accurate. They are for sale right here in the classifieds. Even look like the original, and install the same.

Sounds great. Sounds like I need to get the air fuel mixture correct then jet it a hair richer to compensate for the larger than stock camshaft ( not radical though). Then play with setup springs.

Cool..because the '65's look way different! (when comparing them to the newer units)...

Not telling you what to do............but the metering rod springs were the first thing I did to get driveability dialed in. The weakest spring that idle vacuum would pull shut gave me the earliest enrichment when the throttle opened and vacuum dropped. With a narrow LSA, early mech advance and early power enrichment help make those cams tolerable.
Do you remember which setup springs you went with? Or are there several of these things?

The other thing to check is there are two Edelbrock Performer 750s. One is a leaned out (permanently) replacement for the mild 454/460 trucks - List #1407. One is a true performance 750 with the performance air bleeds - List #1411. No carb should be bolt on and go. So I would buy the strip kit and expect to tune it. Especially with a non-stock camshaft.

This is "currect", but IMO there both "JUNK" period, thats my , i'll say no more

Not specifically, they were just the lightest ones available. These were the Carter products, Edelbrock probably sells some too. Just buy a few sets/pair and try them out. Kind of fun to play around with.
Intresting...what effect did the lighter ones have?

Hello: Buy the Kit from Edelbrock and you'll have all the springs, rods and jets you'll need. If you really want to get into things also buy the book "How to Rebuild and Modify Carter/Edelbrock Carburetors" $24.95 Car Tech Books Type in >carburetors< in their search box. Then you to can be an expert..LOL Good Luck Maynard

Yes I would get the electronic replacement VR, it's a far better setup than the problematic OE electromechanical one and Mrrandy on here sells an electronic converted one w a black cover that looks OE for $27 to your door and your parts house has an electronic version, a "Wells" brand either a VR706 or VR607 (I think VR706) that bolts on/fits OK but does not look OE & if you have converted to a later higher amp 2 field terminal alt (excellent plan) you can just ground 1 alt field terminal and what I did was to trim the sides of a '71 up VR and it will then fit neatly into the squarish recess in the firewall where the OE electromechanical VR once resided
