There's something deeply satisfying in an oldschool blower setup like that. Love that stack.

Who doesn't love a giant roots blower on a stuffing-centric holiday?! haha. Awesome content as per usual. Happy Thanksgiving, HpM!

Love the videos. Love seeing motion race works parts on so many builds nowadays too. Made in the USA!!!

Hey Horsepower Monster. Now that would look fantastic in my 1954 Fargo. I couldn't run it because I would twist the frame into a pretzel. Thanks for sharing.🍁👍👍

I LOVE IT!!!!! STATE OF THE ART IN TECHNOLOGY SPOKEN HERE!!!! TOTALLY AWESOME HORSEPOWER SPOKEN HERE!!!! THANKS FOR SHARING!!!!! SO MUCH FUN!!!!

Cool car! I got to see that car, when they painted it. My aunt was banging the guy who owned the shop. She introduced me to all these guys too. The chick's really dig me.

That polished blower helps act as a mirror so you can see around that big thing sitting in front of you when you drive! LOL

What I like about your builds is that instead of just throwing tons of money at the engine, you guys use your head and make sure everything you add on or modify WORKS and has a definite reason for being in the motor. P.S. Besides muscle cars I've had 5 VDub Transporters....so this has a special interest for me. Of course, the BBC is a known quantity, too. Doggone - when you fired that up with the blower, I was afraid it would throw the belt......are you sure you don't need another spring-loaded tensioner? OOPS! Spoke too soon! LOL

there's just something so wonderfully wrong about a giant blower with 2 carbs on top of an LS. i absolutely love it. great video as always

Just wanted to give the guys a big thanks for helping me decide which pistons I would use in my 383. I was torn between the old standby Weisco and the DSS fx series. After seeing a few builds from Prestige using DSS I went ahead n took the leap. When they showed up I was more than impressed!! Top quality and all wighed +/- .05 grams

That boost line is so beautiful, gotta love superchargers

Wasn't expecting a complete engine build up video. I'm currently working on a 454 that's gonna get a 8-71 BDS blower so this was awesome, subbed!

Looks crazy

This is the best informative engine build channel on yt. I love watching these. THANK YOU for the details. Noboy reall like to share much you know. I mean, some do, but this is better ; )

Awesome as always, excellent builders and narration.

Add velocity stacks and filters= higher than the roof. good fun. Awesome content.

love the channel makes my day so much better

great video .....that is one beast of a LS

Came back to watch again. Yep, it’s real.

Clean build as always 🤟

Oh I want to see some of those sweet 1871 blowers, make a build video with one of those monster blowers

Gorgeous motor

They could've gone with a turbo EJ 2.5 in the back for handling and plenty of speed but this is just showing off. It does make a statement. Not sure what it says but it says it loud. Well done.

I'd say at least a case of beer to come up with something like this. Lol.

Badass 💪🏼🏁

Nice I'm working on a LS with a 871

A motor that big in a “Thing”….. unfrickinbelivable………👍👍👍👍👍👍👍👍👍👍👍👍👍👍……only in 🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸

The blower belt seems really loose. Is that correct?

That would look awesome in a speed boat

Ive got a goofy little combo going together! I'm using mostly stuff I got laying around, I did some trading last year and ended up with a aluminum L33 5.3 block and I have a few good sets of gen4 4.8 rod's, Pistons and cranks I picked the best ones weighed all the rods and Pistons there all within a gram with rod wrist pin piston and rings I was proud of that,picked up a rebuild kit from TSP arp rod bolts a BTR blower cam that's probably a bit much lol some of there 120$ push rods ls7 lifters some .660 springs and some lifters I already had with trunion kit in them a set of 799's that have probably been decked as much as possible they have had a rough life lol ls9 head gaskets some arp studs I'm running my old summit brand 102mm sheet metal intake and throttle body (I went to a Holley low ram 16 injector setup last winter in the race car I swapped to methanol in 2019 and was running 8 precision 550's but struggled with the tune then picked up some billet Atomizer 325's and hated them They stuck open all the damn time so I went back with what I know Bosch 210's 16 of them lol) I'm running Bosch 210's and gonna run e90 and Holley EFI but the fun part is the tourqe storm blower and I pulled out my old air to water intercooler and 5 gallon ice/water tank Ive never had a blower car just turbo and nitrous it should be a rowdy little feller it's in my 77 nova my pawpaw bought new and the first car I Ls swapped and turbo'ed I've got a pretty nice glide and ptc converter and the 8.5 10 bolt is filled with strange axles gear and spool the car has been 5.90's with a sbe 4.8 back in 2016 it was sketchy getting it slowed down with the factory disc brakes and drums out back lol it's just been sitting so I figured the old girl deserved some love so I cleaned it up and fixed any half ass shit I previously did went to a 1" drop Calvert leaf springs and painted the old caltracs and replaced the strange single adjustables out back with some doubles a buddy helped me out big time to get some decent brakes on its got strange disc brakes on all 4 corners now it really needed it back when it was running I had to put a parachute on it and used it quite a bit it had to be around 3300-3400 pounds and trapping low 120'smph it's gonna see alot of street miles so I pulled the 10 gallon cell and picked up a plastic summit 15 gallon and a Holley dual brushless 450 drop in cell fuel pump setup it's pretty close to being done I'm waiting on some solid state relays and aluminum pipe to finish the intercooler and charge pipe and lots of little things that are just agravating I've been waiting on my 7" Holley dash screen I bought my terminator ECU used and not a fan of the little 4" hopefully it will be done by early February I can't remember what it weighed with the turbo setup but I'm hoping to come in at less than 3500 with me and go 5.70's maybe .60's lol and be able to make at least 100 mile round trips no problem on pump 93 with a splash of VP's octane booster or boostane the compression the compression is a tad over 10 to 1 and I'm not the best tuner and As good as Holley EFI is I don't like to count on it correcting and catching my mistakes lol we only got one gast station with e85 in north Alabama where I live so I have to order my fuel anyway Ive always ran ignite E90 it's good shit and not super expensive for a 55 gallon drum not as cheap as M1 tho sorry for the long post I'm a maintenance man and production is slow today so nothing is really tearing up so I'm just chilling in the parts cage! LoL

loved it the ls but one would think bds would manufacture there intake ti fit applications without drilling new holes.

I have a big 2.5 inch cog pulley on my alternator/water pump/crank, guess I should loosen it up some!

I want one for my Mitsi mid sized people mover please.

- Å fan!

What a better than 427 ls with roots blower on street carr

I would love to see a 10-71 Detroit Diesel, make it a 72 degree V10 with N90's and a pair of aftercooled S480 turbo's pretty please.....

Awesome build & final product. Same build using a procharger ? What would the difference be ??? Great video, as always.

How do you not get demonetized from the Brittany music? Good video.

Are there any performance benefits of a roots over a twin screw? Roots are less efficient and make more heat, but are used more often. I know twin screws are prone to blowing up when moving too much air, but I figured there would’ve been a modern solution or technique for preventing explosions.

I still would add a guide pulley to the blower belt to reduce to unnecessary flapping

What can you do to stop the belt from slappin around like that ? Add a second tensioner with just enough tension to kill the slap ?

some of yall in this comment section talking about semantics of blower nomenclature are silly

Can I get a part number on the cam shaft?

So I haven't watched the entire build video but dayum...if this engine isn't capable of making 1500-2000 HP with 23 studs per head, forged internals (limited to the rods in my experience with Eagle), and the awesome cam specs, then idk what is.

What's the O.D of the push rods?

Nothing exceeds like excess

I wonder if this would fit in my wife's Kia Sedona...

A beautiful engine in one of the top 10 ugliest cars ever. I love it. I’ve always wanted a vw thing just because it’s so damn ugly

ONLY 9LBS OF BOOST! Boost is just a sign of restrictions. You could make 1000hp at 9lbs with a larger or more efficient motor.

Good job old Adolf didn't have that type of power in DKW'S back in the day. Just might have change the outcome of ww2😆

why did he put Teflon on the rocker bolts?

Big is 14:71 and above.

He doesn't need arp studs he's better off with factory studs saves money still holds

Problem with all those head bolts the head gaskets don't blow, you just blow up the motor or crack the heads.

Why doesn’t anyone ever put an idler or two or even a tensioner to keep that belt from getting slap happy? That shit isn’t good for those belts. I use them industrially and you’ve never ever see them allowed to slap around like that. Edit: yes, they do not like being tight. However letting them slap around like that fatigues the crap out of them. They should always be snug and under control.

lol, dont make sense to do that to an airboat, they got a 6000 rpm limit and the propeller, looks cool but not practical you can only turn a propeller so hard before it splinters apart and kills somebody

Certainly the testosterone of the BDS blown LS engine was offset by the estrogen of the music.

Could pick a better song

smeagle voice "go away. and never. COME BACK! stop giving us ideas on how to waste our precious"

Blower belt is too loose

The compression ratio was so dissapointing

There is no 10-71 gm blower. 2, 4, 6.

Shit block

That engine ain’t even a Chevy anymore it’s like 50+% aftermarket isn’t only the block besides the main caps stock?

Too much belt slop

Belt control is less than desirable.

Calling a roots blower that goes on a v8 a 10-71 is kinda dumb. Rather I’d call it an 8-89 blower as the 8 always referred to the number of power units it was feeding air to, and 71 was the volume of that power unit at bdc. In this case it’s flowing enough volume to feed an 88.75 cid power unit, so round that to 89 for simplicity.

What a waste of a good motor there's no way that car or that thing LOL we'll ever hook up or handle the horsepower waste of a good motor in my opinion

Doing all that for 10psi Boost.??? Seams like a waste of money and space. On my Diesel Chevy 6.5L I was running 27 psi with a stock Turbo. Not to mention all that noise, who wants to listen to that screeching all the time? It's like sand paper on my ear drums.
