Hemi Swap: Transmission choices for Gen III 392 Hemi

[392 Cuda]

I'm almost ready to start my hemi swap and I cannot make a decision on the transmission.

My Build:
- 74 Barracuda, original 318
- 392 Crate motor and Mopar engine controller, TTI 3" exhaust
- AlterKtion front suspension and Street Lynx rear suspension
- Wilwood 12.19" drilled/slotted all around, manual 15/16 master cylinder

I live downtown Chicago, and I don't think a 6-speed would be much fun if the traffic.

Transmission options:
- 727 with manual valve body, GearVendors overdrive
- A41 Perfect fit transmission
- Wait for a good 8 speed kit and find a boneyard trans (soundgermanautomotive.com claims to have figured out the harness, but has not yet produced any kits)

What stall torque converter?

I would appreciate any experiences or opinions...

Any reason your not considering a 500/518?

I have to admit the 8 speed in my truck is pretty darn impressive. It's the best automatic I've driven by far.

@1 Wild R/T, I thought the 518 required more customization, and still required a manual overdrive. Is it easier than I am thinking?

518 bolts right up to your Hemi, it requires trimming excess webbing from the transmission to allow the trans to fit into the tunnel & a custom crossmember which US cartool sells....     http://store.uscartool.com/Transmission-Crossmember_c_82.html

Patc sells parts to make the O/D & convertor lockup to work automatically...    https://transmissioncenter.net/shop/patc-727-to-518-46rh-conversion-kit-click-here-for-727-to-46rh-swap-wiring-diagram/

If you are looking for a 518, I have a NLU two pin rebuilt I need to sell. I have the crossmember as well.

I've been running a 518 behind my 340 for 2 yrs now and it's the best mod to date.
My next project is the Gen3 swap and the plan is to bolt up the 528.

I had the 727 manual valve body on the 392 originally and while it worked it was not much fun.  I did a swap to a Passon 4 spd OD and it really woke up the Hemi.  This engine loves a manual trans if you can swing it, plus its way more fun driving the car rather than just riding along IMO.

@Katfish, Did you have to modify the tunnel for the tail of the 518?

[Katfish]

No floor pan mods needed, direct bolt-in with the cross member.

We are putting a 5.7 in a 72 Challenger. I have a NAG1 and a 545 but decided to go with silver sports A41 auto. It all fits in the existing location, you retain the slap stick shifter. They even make a plate that is the same as original except it says 1,2,3, D instead of 1,2,D.
