Supercharging a Mopar Slant Six - Pt.1 - putting the Aussiespeed kit to work!

Published 2022-05-12
This little 1965 Plymouth Barracuda needed something a little hotter under the hood. We decided to skip right past the run-of-the-mill V8 swaps, instead cobbling together a retro polished blower kit crowning the 225ci of bulletproof Chrysler power. Follow along with a cup of joe for this moderately detailed but relatively straightforward installation, mounting a B&M 144 supercharger to a mostly stock engine. BCG will be covering installation, supercharger rehabilitation, mounting concerns... and even recommend some of the products to employ to make sure your blower performs like it should... if we don't blow it all up in the process.

If you've got an oldie and want to get stupid with it, maybe check out www.aussiespeed.com and see if they have anything for you. Inlines, orphan cars, right-hand-drive stuff... hard to beat the cool factor of finned aluminum! (or alu-mini-um if you're across the pond?)

Editors' note- these videos were taken over a few weeks and some whisky-soaked late nights, so there's some rambling and a little double coverage of some things... if you don't like the video feel free to request a refund! ~H

    I owned a slant six Coronet station wagon with 3 on the tree. I’m so glad it had that iconic engine. It wasn’t fast but fast enough to get me in trouble.
  • You of course know these awesome slant 6's have bigends as big as a 350 Chev V8's mains, and mains the same as a Hemi 426, so with a little balancing and sump windage system, you can't go wrong (with the correct cam lift and duration), my first was a 63 Torqueflite Valiant single barrel carburetor and the torque was amazing 👏 thanks for choosing my favorite engine and brand, and for sharing your experience and experiment with us 😀
  • Wow..Just found the video...I am a big fan of slant's, have one in a '38 Plymouth....Cant wait for part Two, "Hurry up"

    When you use exhaust wrap it's best to wet it first , stops the fibreglass dust and needles floating around and when it's wet it tends to mould its shape to the pipes better

    The old school roots looks just right. This makes me want to buy an old Dodge truck.

    Slant 6 engines are awesome it was what was in my first car when I was 16 and I'm 43 now and have a super six that came from the factory in my 1979 D100 and I have another slant in my garage on a engine stand that I have put higher compression pistons with a street/strip type cam with aftermarket 4bbl intake and aftermarket exhaust manifolds and the head has had some porting and valve work done on it. anyway love them engines and love seeing what others are doing with them. I need to get a camera out and make a video of it one day so I can show off what I have done to mine

    Had to prescribe to this. It’s just the crazy medicine I need! James, St Louis

    Awesome... just awesome... I'm super excited to watch this series... Picked up a 76 Scamp last year and have since rebuilt suspension, new seats, new vinyl top, working stereo, etc.... soon will be time to modify away from the anemic 1 barrel carb... I've been thinking of the Torqstorm, but watching this series will give me more ideas! Keep up the entertaining vids!

    Slant six's are bulletproof my '70 Valiant blew the no 1 cyl and that still got me through high school and 3yrs of my first job I then sold it to my neighbor and i still see that car built up....40 YEARS LATER!! Every time i go back home I make him an offer and we laugh on my begging and him saying no.

    ...my hubby sez from experience in his pre-aviation tech days, MoPar motors' weakest area of their blocks were the cast iron moror support attach points...realize that 6bangers were built for torque values, and came out of military uses...then after WWII, the engineers were freed up to adapt these odd motors to the truck industry first...and then when the "compact wars" began in the 60s, the "Big 3" began on the draftsmen drawing board the adaptation to these "downsize" vehicles... GM had the famous "Stovebolt 6" Then FoMoCo developed the 300c.i. tug/truck 6 from/for commercial aircraft G.S.E ramp service. And, of course the old Chrysler had the advancement flat-head 6/primarily fork lift/stationary ground power generator power industrial transition into autos of the 30s-50s. Society of Automotive Engineers seemed to either share basic ideas until the shift to "economy" motoring began.

    Great motors even here in Australia the famous slant 6cl , 225 cubic inche 👍 we even had that motor in the flat bed dodge trucks here
  • Some people don't realize that the original slant 6 inlet manifold was actually especially designed to give the 6-1 cylinders longer branch for more torque at certain rpm and shorter for 2-5 for higher rpm torque etc for equally spread power range, so it wasn't just how it turned out for the casting design but well thought out, also it was as you know, a problem with cold intake manifold as soon as people added headers, my best resolution was I used LPG 110 octane with my 215psi cylinder head, but previously to that I used a 350 Holly and had no flat spot on acceleration, but I can't wait to see the blower giving what they love the most, lots of oxygen and the colder the better 😉. PS don't forget to connect your main vacuum to the other side of the blower and not on the manifold.
  • Well done, I have a Torq Storm supercharger on my 69 Valiant slant six. Headers wrapped the same.
  • Got me subscribed. Torn between the Aussie speed rout vs the torqstorm.
  • Great job but needs a volosaty stack air cleaner as the nostalgia thing not the sparrow catcher can't wait to see it finished.
  • Love the video,i couldn't tell when you installed the rotors into the case but have you thought about installing 3 or 4 lobe rotors in that case later on ,thanks
