so at this point I decided I was going to jump into the gen 3 stuff and not build the 340 I had. did what I thought was a lot of research but learned you can read all you want but doing is a different story. so I started looking for auction donor cars and came across a srt8 charger.
1967 Plymouth Valiant Gen III Hemi 11.42@119 youtube.com/moparman619
make a dumb decision and take the chance and buy the car thinking the motor would be fine and hopes crushed. insurance job I should've sniffed out. you live and you learn
1967 Plymouth Valiant Gen III Hemi 11.42@119 youtube.com/moparman619
so i recoup all my money selling parts from the charger and make a little on top (still didn't make me feel any better lol) and start plotting my next move. also this is the first engine I tore down so that was good for the learning process. ok so in the mean time of figuring out whats next for me I start my search for an 8.8 rear at the junkyards. then pops says he wants a dana and would make me a deal on his 8 3/4 with the offset shackle set. DONE.
1967 Plymouth Valiant Gen III Hemi 11.42@119 youtube.com/moparman619
next I find out since I'm using a slant 6 k member the only mounts besides customs I can use are the schumachers. order those and start mock up. gen 3 w/ 727.

Are you putting oil lines in that pan for the turbos? Interested to see how you do it, because I might be doing the same thing at some point. Great build and thanks for posting your progress.

playing with some bends on the hot side. with a truck front cover and a car intake the alternator location needs to be manipulated. also look where I shaved/ground down the front cover under the throttle body to use a car intake.

next I was in the market for a cable driven throttle body. bbk were kinda pricey and efisource was just releasing adapters to use a ls throttle body. I know I know. heres link for adapter https://www.efisource.com/wp/shop/gen-3-hemi-throttle-body-adapter/ and the throttle body is from warr performance. tb is 92mm and I believe the intake open is only 90mm or so. needs to be bored

I use a Ford 5.0 style BBK TB on my turbo 383. It has never once complained to me about the OEM origin, it's sucked up every bit of air that's gone through it.
The alt is going up above the turbo? Is there not room to put it over on the driver's side somewhere and still run a belt the right way for the waterpump?

That's what I was wondering...but with the truck cover it might not be doable, the Auto(LX/Jeep) cover you can mount the alt over where the Air Compressor would go.

but on trucks it sits up there where the a/c sits on LA engine, right? He might need to use the little denso unit instead of the one native to the car.

44mm wastegate vs 60mm. the 60 I ordered when I ordered the turbo but its massive in an already crammed bay. going to try a single 44 then add another later if creep is a problem

I've seen some BIG holes in these G3s, this was a Turbo 5.7 with a stock cast crank, it let go around 1000hp, #5&6 journal came out the side of the block. , the rear hole was cut to make it larger .front of the block was dissected.

I wouldn't worry so much about the rear end until you start trying to launch hard. Launching soft and bringing the power on down track to learn the tuning should be easy enough on the 8 3/4. I'm still at a 'low' power level but the 8 3/4 in my 70 Fury has been fine with a 12psi 383.
yeah ill have to see how it works out. are you turbo or pro charged? whats your combo and how does it run?

first pass Friday: I pull into the water box. get tires spinning and as I pull out the car shuts off. I had no clue what happened but thought I blew a coupler off. idk why. but had them push me back. popped hood. everything looked fine. fired right up and drove it back tot he pit to diagnose. bummer cause you only get two passes a day. I just wasted one. 2nd pass. drive around water box figuring im gonna just ease it down to get some actual data beside my street driving. walk into he throttle and before the 60 car goes limp. 2nd pass. a bust. at this point I realize my tune is way off. tuning with no ice in the tank makes a big diff in required fuel. lesson learned. I throw ice in the tank and drive it to the airbnb for the night. on the highway I datalog and jump on it a couple times and adjust the fueling hoping for better results Saturday.

Saturday. first pass. I do a burnout and the ca his still running! cool. lol. roll into the throttle hit every gear and it feels good. first pass in the books! its only up from here. 14.13 ! Ive got a 14 second street car ! never thought id be so excited to run a 14. all the hard work made it down the track!
1967 Plymouth Valiant Gen III Hemi 11.42@119 youtube.com/moparman619
guess I should mention pump 91oct. 3.23 gears. and making 6-7lbs. 255 radials. shifted it at like 5500. engine never made it past 6k. timing very conservative.

second pass Saturday. I was feeling more confident in the car but still didn't want to break the puny driveshaft or the gears so I planned to roll into it again but a lot sooner than the first pass lol. well the duster I ran mad that easy. he jumped out on me and my foot got heavy real quick. ca ran decent. more data. 12 second street car! same timing same boost.

https://youtu.be/m_8ZQwaizP8 New personal best. Same boost since the first time out. 6lbs. After reviewing logs I’m not even leaving in boost. Next time I make it to the track I think I’m going to leave the tune up the same and focus on cutting down the 60. I’m sure theirs some et to be found in doing so. Anyways. Hope you all enjoy!

you'd be my best friend if you taped your hotside for a pressure gauge to test backpressure. You can use an oil psi gauge and a copper line, I did that with my Fury when I upgraded turbos to see before and after results.
I have the 5.7 sitting in my Coronet now and the dump truck 76mm T6 I have is big in there, not to mention its 5" exit.
im def game for that. so much to get done on the car. but ill def post results when i get to it!
