    318/8 Speed Swap

    2.94 is a great gear too, a little more responsive than the 2.76.

    318/8 Speed Swap

    Sound German has a gear indicator display so you can see what gear you are in. Possibly, Dakota Digital dash may have that too? Not sure... Dion..yes I think the 2.76 puts me right where I want to be, with your info backing it up. The V6 weighs in at 3886 lb, so I am still about 500 lbs...

    318/8 Speed Swap

    My car has a 2.76 gear in it now, 8 3/4. You would have to find used for that gear. I need a sure grip still. From what I understand the C bodies had 2.76 sure grips. Also thinking since my car is probably 900 lbs or so lighter than a new challenger, the 2.76 might be just right. I could...

    318/8 Speed Swap

    Reviving this old thread.... work has finally begun getting the 8 speed in. I changed direction on the flywheel from the QuickTime -947 to a kit from JVX Racing in Tenn. He has a full installation kit to make the easy (he also sells the kit and adapter for a big block). Tunnel was cut and...

    318/8 Speed Swap

    Hi Johnny, I never tried moving it in or out. It is at the shop with the car so I cannot try it. Maybe the next time I go down I will see how much movement there is. It isn't just for harmonics as the ram truck has a full floating rear axle like our cars and they have quite a bit of travel in...

    318/8 Speed Swap

    I've also been playing around with the shifter. The easiest would be to just mount the new shifter in place of the old slap stick. The sizes are close (I mounted a old style pistol grip to the stalk, not done yet). The stalk needs a sleeve to get it to the proper diameter but I think it will...

    318/8 Speed Swap

    I don't recall what it came out of as I bought it from Craigslist. I do have part numbers off of it... P52123616AA its at the shop with the car but the part with the slip joint, the length is close for a barracuda, challenger would be a little longer of course. I think it will need to be cut...

    318/8 Speed Swap

    Hello Mgo, I am in Fayetteville. I plan on using the 2 piece driveshaft from a ram but I think it was from a rear wheel drive. The second part of the shaft has the slip joint. The front section has the output mount for the trans so the plan is to remove that and put on where it joined the mid...

    318/8 Speed Swap

    Hi Steven, I am going to use the controller from Sound German Automotive. I've spoken with the owner, Russell, who also developed the controllers. His controller only needs a TPS, brake switch signal, RPM reference - tach signal. The controller otherwise plugs into the transmission, using the...

    318/8 Speed Swap

    We are using the QuickTime RM-947 plate. It needs to have the TC holes drilled into it. I was thinking of using the stock 8 speed plate, but it would need the hemi crank bolt pattern holes welded closed then drill the 6 bolt crank holes. Last step would be balance checked.. A lot of work for...

    318/8 Speed Swap

    We are gearing up to get to it this year. My friend and I both have the transmissions and related parts. He is pulling the engine and 727 real soon. His will probably be in before mine as I am still on the road runner. If only I had more garage space....

    Torque converter for 42RH swap

    It is, we were talking about the 42RH but I am using the info towards the other project too.

    Torque converter for 42RH swap

    I am running a 71 318 with stock crank and rods, new balancer for a 318. Build will be like the Hot Rod mag. "Junkyard Jewel" but with retro roller cam and aluminum heads. My friend is running a 73 340, external balanced with original harmonic balancer and I believe a B & M flex plate. He...

    Torque converter for 42RH swap

    Plum, so it depends how the engine is balanced? You internally balanced the engine so the convertor can be "neutral balance". Is that correct?

    Torque converter for 42RH swap

    Thanks Transman for the excellent info.

    Torque converter for 42RH swap

    Transman, do all converters need to be balanced to each engine anytime you put in a different converter? I am changing a trans behind a 318 and a 340. What about the flex plate?

    driveshaft experts, quiestion about dents in an aluminum driveshaft

    I've been looking to use a Dakota aluminum driveshaft after I do a transmission swap (don't want to shorten original shaft, so need another one anyway). I was currently planning on using the 42RH so the shaft/ yoke would be correct on the front end. The rear would need a u joint to work with...

    318/8 Speed Swap

    Thanks Kursplat but I would like to keep all the geometry set. I am trying to find the easiest/ cost effective solution (without large modifications/changes) to make it work; thinking aloud. A modified oil pan can be replaced with a stock one at anytime; so no harm done as with anything "bolt on".

    318/8 Speed Swap

    I am not interested in cutting the floor. I see what you are saying about the drag link so probably the safest bet is to modify the oil pan.

    318/8 Speed Swap

    I've been thinking more on this subject and am seeing that to lower the engine (as not to have to cut out the car, helping with clearance for the trans) the drag link is the closest thing in the way. I've thought about doing the torque tube idea through the oil pan. I've just thought about a...

    Appreciate the videos as well but your installation is not behind an LA small block, which this thread is about.

    318/8 Speed Swap

    Talk to Hemi Denny's company. They may be working on a way to get that in an a body without too much cutting but since those bodies are smaller with less room, I don't think you have much of an option. I know US Car Tool has a lot of options for support structures, so check them out too.

    318/8 Speed Swap

    Hey Travis, I don't have any further information. I have been doing some research on trying to get the engine mounted lower though. Since my car is apart, I don't have any direct info to try but I've been asking around. So far I know this, if using the Gen3 hemi with this trans, Holley and...

    318/8 Speed Swap

    ChevelleGuy, Yes, thanks for all the pics/info. Do you know what drive line angles you have, front and back? I am wondering with the CV joint should you maintain a close to 0 or very small degree down on the transmission side and maybe less than 4 degrees up on the rear differential side...

    318/8 Speed Swap

    Hi ChevelleGuy, welcome to the board and thanks for offering your help! I do have a few questions. As far as a controller, contact Russell Drake at Sound German Automotive. He is the go to guy for a controller. 1. Did you use a Chevy flexplate to attach to the torque convertor? 2. What...

    As for the issue of the flexplate, can this be used to mount the TC to this flexplate then to an LA crankshaft? PRW 1834500: Gold Series SFI-Rated Chromoly Steel Flexplate Mopar 5.7L/6.1L Modular Hemi | JEGS

    318/8 Speed Swap

    Let me know what you have in mind, Wish. I just recently read, I think on Facebook or somewhere, that if the engine is moved forward slightly, the transmission can fit better in the tunnel. It wouldn't be necessary to cut the tunnel. I don't know how easy it would be to do this with an LA on...
