8 Speed AT in 1970 Charger

I've done the Gen 3 conversions with the Tremec 6 speeds before, not hard at all. Now in my newest project, a Hellcat with a 8 speed trans. Who makes the trans mount conversion? Any other pitfalls I need to need about?

Holley has the trans mounts. Not sure on pitfalls other than tunnel clearance and the usual driveshaft conversion stuff

boy that was a lot of work. Holley makes it sound like you just cut out the cross member and use their system, not all that tunnel work.

True, and I wouldn’t want to cut up a Mopar like that unless it’s a low-dollar car.

I'd hate to be the guy that did all that work to that car and youtubed it if you really can just cut out the cross member and use the holley mount:

they only have this for B bodies so far for some reason.

I think there's a point when if you want all this stuff, you should just get a new challenger lol

that's not what it says....

"1966-72 MOPAR B-BODY GEN III HEMI SWAP COMPONENTS"

This particular part says 68-70 b body, not just Charger.

Isn't the b-body trans cross member fairly close to the e body?

My friend and I are each putting the 8 speed in our e body cars. I won't be ready probably until next year (for the body mods) but we are now working on getting the 8 speed to properly mount to the small block crank, figuring out flexplate spacing, tq mounting, etc..

you're using the TF8 with an LA engine?

Furious, yes. Mine will behind a hopped up 318, his will be behind a hopped up 340.

this is such a really cool idea, i hope this works out for you. What flex plate etc to do the swap are you using

We are using the Quicktime -947 plate, it has to be drilled for the new TQ. We thought about using the stock plate but I talked to Ross at QuickTime and he said it is easier to drill the holes for the converter than it is to drill the holes for the crank. Plus the balance on the plate won't change when drilling the holes for the converter (symmetrical) as it could with the holes for the crank (non symmetrical). The tooth count is 1 less vs. the stock 8hp plate (130 vs. 131) it shouldn't be an issue.

Our next step is to get the spacing off the crank to the plate/converter correct for the input shaft and starter.

Didn't mean to hijack the thread from the original poster.....

FYI the next generation 8spd has an electric motor in it with something like 235hp and 335lbft

Really?.......

Any more info?

"Previously confirmed with electrified assistance by the head of sales operations Matt McAlear, the all-new Charger and Challenger with the fancy 8HP box could arrive in mild-hybrid, hybrid, or plug-in flavors. The most powerful transmission is called 8HP80PH, and in P2 setup for plug-in applications, it cranks out up to 215 horsepower plus 332 pound-feet (450 Nm) of torque.

Combine these figures with the 6.2-liter supercharged V8 of the Super Stock that develops 807 horsepower and 707 pound-feet (959 Nm) on pump gas, and you’ll get 1,022 horsepower and 1,039 pound-feet (1,409 Nm) in total"

Dodge is showing off a new car on July 8th

Nice. The wife's 2020 Mercedes GLE 580 has a hybrid setup with an electric motor in between the engine and trans and it provides 30 hp and 120 lbs more torque to the biturbo 4.0.

Holly's cross member will not work with the 90, just the 70.

hmmm, I've not seen a difference in the cases documented - do you have any photos?

I have no idea but Ive seen a couple youtubers swap the 70 for a 90 in LX cars and none of them mentioned any difficulty
