8hp70 transmission crossmember mount
The HDK mount is what I'm referring to...4.7Light cut up a mount that was intended for a NAG1, if I recall, and a universal x member support.
It looks like the hoop bolt might be exactly where my connector pops into the trans. I barely clear the x member now.. but I do need to cut a little more off yet. So the HDK may be fine as well. Just hard to tell
For Denny's set that's for a Hemi 6.4 and moved forward and he used stock location cross member trimming of course. Very little tunnel work as well again Hemi is not for the weak you will be doing more than just this. Watched him share his work amazing kit if your going that route. I bet you could move the 360 forward they make a motor mount to do it.
On mine I had the built LA 360 and cost on my side this was super cheap. Amazing value for what a built 360 can do in front of an 8HP. I drive it everyday if I can grocery store anywhere!
My setup is trimming the left and right side cross member just behind the holes then I put a plate square closing that all around. I used a 3 inching dropped Mancini transmission mount. I put in 2 x 3 sqr tube frame connectors and then put the drop mount just behind it dropped right in easy peasy I probably went over board on trans tunnel but I wanted to have lots of room and my feet are fine. I also used 14 gauge cold rolled steel tunnel and made it much stronger. I got plans for turbos on the 360 someday and I need to make sure it won't twist.... it won't.
This swap is NOT cheap
transmission is like 1000
controller 1000
Driveshaft 400 and up
Adapters drive shaft and flex plate about 500
Auto Shifter Challenger style wanted brand new Mopar that's bling bling 500 to 600
Cooler and line 300
TPS 200 Holley
RPM converter or ECU with square wave 5 volt
I used a NAG1 hoop but looking back now I would make my own simple.
So yeah 4000 to 5000 it's not cheap it is a game changer ask the mid high 11 I run now with ease and I don't know what the heck I'm doing Im just mashing it and holding on.
I also plan to track the car at Hallet local near me on Oklahoma and with this transmission will for sure let me do that. It's great fun flip shifter to the left and for some sport driving on a curvy road.
Best part is this made my car plain mean fun it's so much fun shocking the crap out of cars that expect to knock my doors off. Tesla got shocked and a few bikes now. They don't expect a crappy Dart to pull on them lol. Car scares the crap out of me now. I got a few runs in quickly to 140 or so last few weeks and it was still going hard. Its not safe now needs some changes bigger brakes different headers sparks at 120 was lots of pucker factor and dumb as hell. I will admit I didn't realize what the transmission would unlock. My 727 did not do this just bad mismatch I guess. I'm using factory tune for 6.4 Scatpack redlines and all.
Working with Russel Drake is amazing as well and check out the Facebook page 8HP70 build la conversion page. I have a write up and all my pictures here and there.
