Im writing this up to make a one stop fact checkpoint. All info I've gathered from various sights and some other sources. I spent countless hours searching the high tides of the world wide web. Finally got a loophole to go through and were makin it happen. I had every company tell me this wasn't possible to achieve. IE (Allstate gear, South bend clutch and quite a few other). I bought a rollin chassis for a very good price and it had an Nv4500 but it was an early case which meant it had the lower 6.34 gearset smaller retainer bolt pattern and bellhousing as well. I actually got around to pullin it all apart and it wasn't too bad. I actually enjoyed the teardown. My 727 was just rebuilt and I smoked it already. So the solution to all the problems at hand. First, the input shaft bearing retainer needs to be swapped, Chevy runs a 6.5 inch shaft and Dodge runs a 7.5. Also the opening is smaller on the Chevy for the retainer so the Dodge one needs to be machined down to fit the smaller case hole. Also the bolt holes for retainer needs to be elongated to match smaller pattern. The bolt pattern for bottom 2 bolts on the bellhousing will need to be drilled through as well. Second, the cluster shaft on the older units are a 2 piece meaning the main gear (4th ) can be pressed off and switched to accept the Dodge input shaft. (38 tooth for 5.61 Dodge and 39 tooth for 6.34 Chevy). Third, the flywheel was a pain in the ace to source. Reason being there weren't any 440s made after 74 with a standard transmission. Which means the flywheel has to be rebalanced for a externally setup motor to accept a 12 inch clutch. Mopar Madness out of Colorado was the only one that wanted to make some money cause he made it happen. If you guys ever need parts that are hard to find he's the guy. I've been told the 12 inch clutch from a 1995 and up Ram truck will bolt right up to an older style flywheel bolt pattern. The flywheel should be here this coming week so we'll see. Lakewood 15335 is the bellhousing I will be using. I'm still looking into how I'm going to setup the clutch slave cylinder. Anyone who has any feed back on this topic can chime in.

# 1 / why not just use a "dodge" NV4500 0r NV5600 / getreg 535
# 2 / there are 100's of thousands of 1974 to 1978 440 flywheels [ ask the dozens of 440 - 4sp RC owners on here ]
# 3 / why the fork would anybody go thru ALL that to to use "chevy" parts in a dodge [ see # 1 ]
Have you seen the prices of these transmission? They go for about 2000 plus. And you need a core to return. I got this trans for 400 bucks. Main Reason I'm using a Chevy trans is so I can run My 32 spline np203 from a chevy. And if I wanted to I could delete my doubler and just run my np205 cause it has the 6 bolt round pattern just like the 4500.

There may be 100s of thousands of flywheels for a 440 that year but they won't accept a 12 inch clutch like the 4500. This hasn't been covered with all the facts in one spot, I just wanted to help the next guy from pullin his hair out.

What "bigger" flywheel are you using?

74-77 Medium duty 361/413 flywheels accept a 13" disc

I was told the biggest clutch for a 440 flywheel was 11 inch. I'm using one from a guy whos rebalancing a internally balanced unit.

you got the WRONG info on the flywheel
All the flywheels I've tried to find are 130t count for a bigger clutch. I need a 143t to use my old starter. I've done plenty of homework and called numerous places and that's what they've told me. If you aren't here to help then just keep your comments to yourself.

Thanks

hate to say but if YOU dont have the Correct info you should NOT post this dribble

besides your title says and l quote = nay-sayers delight

that means your pretty much expecting blow back
and l give you some and your panties are in a twist LOL
That's why it's a (technical discussion). your trying to have a pissin match and saying I'm wrong but have no defense as to how. If I had it all figured out then I wouldn't add at the end of my post feedback is welcome not some idiot who would like to be right but doesn't know enough about the topic. Title says that because I've been told it can't be done and I'm figuring it out, doesn't mean I'm expecting ppl being rude and just blowin smoke up my ass. Hahahahah

My observation with 94+ nv4500/magnum parts listings is both the 11" and 12" clutch fit the same flywheel.

That's correct, I was having lots of trouble finding a flywheel for my engine being that it's externally balanced.

To a point, flywheels aren't specific to small block, big block, etc. Those 130 tooth flywheels came in cars behind 318, 340, 360, 383, 400, 413, 426W & 440s. Yes there are different balances but a flywheel can be used behind multiple engine types.

The 143 tooth flywheel came in light duty trucks from 69 into late 80's. These are the mechanical clutch linkage trucks. A 143 tooth flywheel from a 318 will work behind any other internally balanced crank like a forged crank 383 or 440. Flywheels are "sized" to bellhousings more than to particular engines. Likewise clutch disc are sized to flywheels (diameter) & to input shaft (inner diameter & spline count).

I brought up the medium duty flywheels because there are yet larger than the 143 tooth versions that came in 69-87 trucks.

Yes some flywheels can accept more than one clutch disc size.

I will admit I am rather ignorant on the NV4500/5600 transmissions, but it looks like you have researched those pretty good yourself.

If you are hunting a 143 tooth flywheel for a cast crank externally balanced 440, one from a 400 should work. There used to be a guy in Texas called Cajun Jon who sold new 143 tooth flywheels. I bought one from him, but that was over a decade ago.

Kajun Jon Bergeron was his name. I see he passed away in 2019

Yes, most of them share the same bolt pattern for the crank. The engine I have has a cast crank in it so it was really hard to find something that was externally balanced. Maybe I wasn't lookin in the right places I'm not sure but I've been on the hunt for about 2 months now and so far this is wat I've come up with. Thank you for your input as well, much appreciated. 👍
