I need the round hole style so I checked the ATP Y156. It doesn't list a 383 Dart as being one of the applications for it. This is why I was wondering how the measurements posted are taken. Plus, 19.5" is still a little too long unless there is some way of mounting the cable to accommodate the extra length.
They don't list anything that old in their catalog. I dug onto my 69 parts manual, the pn for a 69 Dart with a 4bbl 383 is 2899337 https://www.moparmall.com/MoPar-PN-2899337-Throttle-Cable-p/808-398.htm

The Performer RPM is significantly taller than stock iron. Also you never said whether you have a B or RB engine. 440 is taller than 383. Do you have the mopar linkage adapter on the 850 holley? Something is weird here. If the cable housing is attached to the firewall and adjusted properly at the bracket ( you do have the correct bracket?) then it should work.

Since your engine is already not stock, have you considered just buying a universal cable and cutting it to length? I've used cables similar to this on on my 440 Dart and my '73 360 truck and they work great. I for one DESPISE those finger pricking POS's ( No offense meant to you I would suggest using the existing cable trimming the excess length off and swaging a new end on or use a brrel clamp likely available at you're local hardware store or lawn mower, bicycle shop LINKY

It's a 400 block and I do have the adapter.and a Mancini high rise bracket. As I mentioned, using the 71 Charger cable, when attached to the carb., and clamped down in the bracket it runs to the firewall and looks like I believe it should (not too short, not too long). But, when I got under the dash to connect it to the pedal, the actual inner cable sticks out about 2" past the little hole it goes through in the pedal arm (with the pedal in the full up position).

I never saw the cable stop before that is shown in the link you sent. That it is something I will seriously consider. Thanks for the link.

Have you adjusted the cable for WOT? Pedal on floor and carb full open?
The Pedal will end up wherever it ends up at closed throttle.

Superglue on the able where you want to cut it usually keeps it together and prevents finger pricks.

He will definitely want one that is longer than the stock BB a body cable. I saw a listing I thought somewhere showing the A body length , it's not on the mancini chart though .

I seem to recall some swap where the Slant 6 cable was the "hot tip", but they're pretty long... Yes it was , think it was in Mopar Action before the current crop of available lengths ?

This is the Mancini number. This cable will work. MRE8668 That might be the 6cyl cable , that one is almost 30" total length

I think I have an old 6 cyl. cable in the garage. I would be happy to measure it for you. Thanks. I'd be curious to see if it is the same length as the one from my car.

As I mentioned in my original post, I tried my original 6 cylinder cable and it is way too long. Post some pictures of what you have going on. This is done every day with available mopar cables and they do not need to be cut.

Seems to me that moving the cable jacket rearward in the intake bracket would effectively take up the slack at the pedal end, wouldn't it ? In other words, pulling more of the cable forward inside the jacket. As I mentioned, I tried that, It didn't change anything.

The factory overall inner cable length should adjust fine. If it's loose at one end it is because either the throttle cable bracket is to far forward. Or the pedal assy is bent (unliklely). Who's bracket is it? I always make my own. The only issue with using a factory long cable like a 6 cylinder is you may hae to loop it a bit behind the left head. The relation ship between th einner length and the outer casing of all factory cables i ssimilar enough to allow adjustment. I can cut and weld it for you if you need. Get a measurement of where it needs to be. I'm in Waterford Mi. Just finished one for the turbo Duster project I'm working on. Doug

I have a similar bracket as the OP and I think I can just weld an extension on the existing tab and move the clamp stud backward about an inch.

Exactly , in the picture it's too far forward , loosen the clamp and pull it back till all the slack is taken up, if that puts it off the clamp location then the cable you have is too long for that mounting bracket design. But to me that cable looks a bit too long, what is the length of the jacket itself ?
