Getting ready to do this, just want to make sure I am not missing anything?

Have a rebuilt A833 that was out of a 70 Demon, rods and a new shifter setup.

Have the tunnel piece from the same car the trans came from.

Bought the American Powertrain hydraulic kit.

Looking for a pedal assembly, the one I bought is junk.

Have a Lakewood bellhousing for BBM (I have a 440 in my Duster)

I need to pick a clutch.

the flywheel is the weird part of this. My 440 is cast crank, as were MOST of the 440's made, yet not very many options for a balanced flywheel.

I can just buck up for the Mcleod one that has the weights add on, I have also read instructions on where to get a machine shop to drill balance holes but that seems sketchy. How did you guys solve this? Just pay for the proper one and move on?

As far as install goes, taking out the auto stuff is easy enough.

Cut the tunnel inward of the tunnel piece I have and I will probably 3M panel bond it. I will be careful of the crossbraces right under the tunnel.

I have a new manual carpet to put in. Using a floor mount shifter boot.

Anything I am missing?

Brewer's also caries pedal assemblies; new, used, rebuilt, and conversion pieces for automatic pedals. And I believe they will also rebuild your bad set.
 
I didn't realize they had the flywheel I needed, much cheaper than the mcleod.

On the pedal thing, I am leaning toward buying the Malwood pedal system and using the bearing my other kit came with, and selling the rest. Seems uber simple
 
One last question, when i was originally going mild 360 I had bought the Mcleod 75109 street pro clutch, still new in box.

I ended up going very warmed up 440.... am I asking for trouble being cheap and using this? It has to better than what a 69 charger with a 440 had factory??

69 Charger with 440 would have had 11" clutch. 75109 is 10.5". McLeod generically rates the Street Pro to 400 HP across the board....I think that is pretty generous. A lot of factors come into play....rear axle ratio....tire height....weight of vehicle....intended driving style...etc.
 
Fair points... 440 Duster with aluminum heads, intake water pump and housing so should be very similar in weight to a stock iron 340 car. Just running 275/60 BF's in back, so not much chance of biting hard. 3:91 gears. Driving style, I guess drive it like I stole it will be the plan. I won't get my money out of it selling the clutch, so why not just use it until it cooks. Gives me something to do next winter! Thanks for all of the replies!
 
Would anyone be interested in a partial American Powertrain kit? I am using the bearing and collet, but everything else would come with, brand new. I think a Mopar Ram bearing is fairly cheap to make it a kit again or maybe you have a bearing already. Let me know. You would get the bracket with master, the resevoir, both hoses, and the heim joint and all of the hardware. I ordered the under dash pedal from Malwood
