I agree with Beekeeper. Axle ratio of 3.73 works excellent with a TKO with .64 fifth gear final drive, and running close to original tire height. :cheers:

Pull the steering column connector apart. Make sure all connections are clean and the connections fit tight together. You can slightly squeeze the female ends together so the male end fits tight. Use some dialectic grease on the terminals before reconnecting. Do the same thing to all the bulkhead connections.

Once all connections are good, retest with your test light.

I believe it was the Mopar Performance kit.  I got it from Jegs.  I'm pretty sure I got the installation right, I used assembly drawings from other sources online.  I'll check out the Spicer option, it sounds like a possible lifesaver, thank you.

You would need the AAR/TA style exhaust manifolds to use the exhaust as it is shipped I believe is the simple answer ..

Which are standard 70 340 E body manifolds which are the same as 68-70 A body 340 manifolds.... Which are reproduced.. But are stupid money..... Use stock AAR-T/A tips & mufflers but personally I'd run shorty headers & have a good muffler shop make the head pipes....

Thanks for the info everyone, yes I am very inexperienced but I think I'm not getting across  what I was asking very well. I was wondering if it's possible to use the AAR exhaust with a 318 while building a 340 6 pack on the side and still be able to drive the car. So the 340 wouldn't go in for quite a while. I understand the 6 pack is a pain in the butt, I'm not 100% on It, which is why I was asking about other options too. I appreciate everyone's input and apologize if I'm not explaining myself very well or coming across ignorant. Thank you!

Have 2" TTIs.
Their website gives some good ideas on how to make it work. I think my current tailshaft is causing some clearance issues as well. The webbing on the side is fairly thick compared to the one I'm changing to that has the mounting tab for the torque shaft bracket.
Hopefully I'll get the clearance I need with the new tailshaft

Ok, I was hoping for easy, not this time... If you want to tear it apart again...

I'm guessing you used the sure grip clutch kit from Mopar Performance? They are known to be harsh.. And the assembly instructions that come with the kit are wrong.....
Proper assembly order....

Sure Grip assembly order

1. Clutch hub

2. Flat fiber plate with hole in ear

3. Dished disc*

4. Flat fiber plate

5. Dished disc*

6. Flat fiber plate


*Assemble dished discs with I.D. positioned away from clutch hub. 

Pre-lube clutch pack with straight friction modifier. 


FWIW there's a second supplier I believe it's Spicer, their clutches are known for being much less harsh to the point of slipping when you don't want them to...

I put a Tremec five speed in my 64 Vette. I like it a lot. One thing to keep in mind...I had 3.36 gearing in my Vette and 5th gear was simply too tall. Freeway RPMs were too low and the small block bogged a bit. In the end, I had to switch to 3.73 gears. Check the rpm calculators on the internet to determine your highway rpm's just to be sure you're gonna be happy with the final drive.

340 manifolds bolt right up to a 318..  Personally I'd probably build a 408 or a 414 stroker.....  Good luck with your project, sounds like a fun toy.. :cheers:

FWIW from the outside a 318, 340, 360 or a 340-6 (T/A) all look very close to the same.... Fact is T/A heads are the exact same casting as 70-72 340 & 71-72 360 so unless someone takes the valve covers off they are identical...  On a clone I wouldn't get to hung up on real T/A heads or trying to get a T/A block....  Just build it & enjoy rather than being super anal.... If you want to do a high dollar resto don't spend your money on a clone, get the real deal....  FWIW I like clones & would strongly suggest going that way....
