12 Second N/A Slant 6?
All you need to do to a NAG1 is put a billit stator convertor in it & go race.
The creep characteristics of the billit stator TC will allow streetable stal speeds up to 4000 RPM & more. The TC in my car is rated for 4400 RPM but my weak little old 5.7 only flashes to 3600 but unless you get a bit too quick on the throttle you never know it's there. The TCM lock-up parameters also help streetability & fuel mileage.
It already has a manual slap shift feature (as well as after market paddle shift) or you can let is shift itself in drive. In the stock configuration all you have to do is bump the shifter right for upshift, left for downshift.
Unless you are going forced induction W/800 HP or more, no need to open it up, just run it. I was making about 530 HP @ the crank N/A & hitting it W/a 175HP shot of juice. Never a bit of trouble out of the transmission. I'm still running it W/just over 80K miles on it. Other than swapping a valve body, the pan has never been off.
Guys running forced induction strokers once they were getting over the 800 crank HP level were starting to experince failure.
Mercedes designed these transmissions to hold uo to the big AMG "Compressor' (supercharged) models.
Want a streeetable gear ration that will work well on the strip? Want to have air conditioning & kick a$$ sound system in a car that you can drive across the country to drag race?
Put a 2.93 axle ratio out back & you have 4.13 FDR in 3rd gear, 2.43- in 5th
Put a 3.23 in & the ratios are 4.55 & 2.68
A 3.31 gives you 4.66 & 2.74
A 3.55 gives you 5.00 & 2.94
Will it outperform a Torqueflite on the track? No, of course not, but it will do just as well aside from a bit of a weight penalty, will stand up far better when comparing stock OEM assemblies & allow a very streetable combination.
If you want to have your cake & eat it to, a NAG1 will deliver.
If there was a way @ the present time to run a NAG1 in an "A" body I might go a whole different direction W/my Valiant.
Just throwing this out there as a "what if"?
