- It’s been a couple weeks, not a “hot minute”, but I’m back with a drive video. Not the best audio. Hope to get better angles next.

This is awesome man. Congratulations on it driving without any hickups. Did really well.
Thank you. It’s been very rewarding.
Yeah, buddy!!!! Woohoo!!
I said that couple times while cruising. Lol
Luke thank you so much for sharing this valuable informaton with all of us. Your car is amazing!! With the 3.23 gears, would you say that first gear is useless unless you want to burn the tires off? I am doing the same as you did to a Charger and at this point I am trying to decide which way to go with the rear differential. The Tires I have for my Charger are 26.97” diameter. I have a late model Challenger with the 5.7L Hemi / 8HP70 transmission. It has 3.09 gears in the rear end which seem to be the sweet spot for this combo. Only problem is If I want to go that route, I will need to do a f@#d 9” rear axle which I am hesistant to do. If you could let me know your opinion, I would greatly appreciate it. Thank you Luke.
Your welcome. I have a 6.4 so I may have a bit more off the line but that shouldn’t matter much. I wouldn’t say 1st gear is worthless. It cruises just fine. I may step up to taller tire. But mopar recommends 27” tall with 3.23 gears at least. Sounds like you have the right combo. Also depends on purpose of car is the end.
That’s awesome. I can’t wait to start on mine
Awesome man. I've been driving my Challenger around wanted to do a video. I have 3.55 gears and 275/60/15 and rpm is about 2200 at 75 mph. Just bought a sweet 69 Roadrunner and already thinking of a 6.4 swap. I have a 6.4 sitting in garage already. It's a 4 speed car so I'd probably go with a Tremec 5 speed.
I’m thinking about stepping up to same size rear tires on my car.
5 speed would be awesome. I’d like to be able to hold gears sometimes.
Congrats on getting it on the highway. Just curious, from the time you had all the parts sitting in your garage how long did it take you to get it to here? Seemed like you worked on it at a steady pace.
I’d say roughly six months. I could’ve got it done faster but I only worked on it on weekends. And not both days some times. Not all day. But I tried to set a goal for each weekend. Wether it was get the fuel system in or engine set in.
Awesome! Any issues with the AC compressor turning on the engine with the system not being hooked up? What are the AC system plans?
No issues. The compressor can’t turn on with out a switch sending it voltage. So the clutch just free spins for now. Plans are to contact vintage air. They make fittings that go with these newer style compressors and go with old cars. Just need time and money. Lol.
I have a F5 limelight green 1969 Plymouth GTX i am planning to redo to cruise and go to car shows. Now i see your videos and i am 6.4 hemi and 8 speed interested.
So how much time did it take you to get to this point in the swap? From pulling the old motor to first decent test drive?
’d say roughly six months. I could’ve got it done faster but I only worked on it on weekends. And not both days some times. Not all day. But I tried to set a goal for each weekend. Wether it was get the fuel system in or engine set in.
Hey was thinking of using the dial shifter instead of the t handle one like in a challenger. Was there anything special to use it or just plug it in .
There might be plug differences between them. Reason I say that is when I ordered my trans wire kit from SGA, Russell specifically asked what shifter I was using. Therefore I think the plugs are different, but I am not 100%. I would ask Russell at sound German auto. But when I received the kit it was plug and play for the rotary shifter.
Was this the first drive? Congrats that shes on the road that's a big milestone
Thank you. This is actually the second drive. First wasn’t too far or too long. I was working out any issues, the major being overheating.
i have not picked my rear end out yet I'm thinking about going with 2
3.23 gears and a 27.8" rear tire.
Did you mean 3.23? 2.23 might be too high. Here is excerpt from the Mopar crate install kit, and what it recommends:
Axle Drive Ratio:
The recommended axle drive ratio should be 2.61:1 to 3.90:1 to obtain optimal vehicle performance and fuel economy. A Limited Slip Differential (LSD) or Open differential is recommended for best drivability.
Tire Size:
The recommended rear tire size is 28 to 29.5 inches in overall diameter.
@@LukesGarage yes 3.23. Ok I think I’ll stick with my 3.23 gears.
