665 Cubic Inch (10.9 Liters!) Monster Big Block Engine Build [The Displacement King]

We go all-out when it comes to cubic inch displacement with a massive 665 cubic inch (10.9 Liter) big block stroker with Prestige Motorsports! www.prestigemoto.com
This pump gas monster churns out outrageous amounts of toque on pump gas and is a build you can follow. We show you how to get the most cubic inches possible with a Brodix tall-deck block, stroker crankshaft and Oliver connecting rods. Then to feed all that displacement we use AFR's New 18-degree Magnum cylinder heads and intake manifold.
Prestige uses lots of tricks here you will definitely want to check out. Please leave a comment below and let us know what you think (and what builds you'd like to see next). Thanks!

I took a 1970 454BB, and punched it to 496cid.. it made 1.7hp per cubic inch by the time I was done with it... 777hp... I put a new line of comp cams bumpstick in it and it made it sound like the one in this video as far as idle manners... I miss that car so much... I got cancer and was out of work and so sick... insurance only covered so much... I had no other choice... I lost everything... but out of everything the only thing I really miss is my car and the engine and rest of the powertrain I put into it.. that gave me and my wife so much joy... I’m very very great full to be alive, but I just miss it so much that when I see a real nice muscle car , particularly a nice Chevy muscle car, or hear a nice rumble from a big or small block, I can’t even bare to look and see... makes me so upset to know I’ll never feel that joy again, as I could never recoup that loss now...

[@Acroposthion]

@Dave Allyn, Sr. - There *IS* a difference in building an engine to make full power, for seconds at a time - and a boat motor (of any persuasion) which needs to run at speed and under load for more than an hour at a time. Then do it over, and over. Pushing a car down the highway generally requires about 30hp (+/-). A one-ton pickup, towing rated load on a flat section might use 75hp, steady state. There are only a few places in the US where a roadgoing engine might see full-power for *minutes* at a time. Boats are a different story. Unless trolling through ‘no wake’ zones, boats (airboats especially) ask a whole lot more from their power units, all the time. Obviously an LS engine can be beefed-up to make (and handle) 1,500hp+. Asking it to pull that kind of duty on the regular, is a tall ask. NRE documented building a small-inch, TT-LS lake boat (IIRC) race motor. Even destroked down to 260(ish) CI’s, much was necessary to make an LS last for 15-minute pulls.

sure, i'm well aware of the pounding a v8 gets above 1000hp if more than a few seconds at a time. and shorter strokes is where it's been at for over 60yrs now(for longevity and reliability)--is why i wouldn't make a 5" strike motor and run it past 4k if i wanted it to last. midas well put that thing in an airplane cause it's stroked and bored very similar to a 500hp av gas motor that doesn't rev up above 3k. Nelson Racing has a premiered video on a 260ci LS with piano wire hoops on the cylinder tops and dino'd out above 1500hp...and ran above 9600rpms and he couldn't kill it. that also was for a boat. so yea, i know.

@Dave Allyn, Sr. - That is the engine I referenced in my post above, yes.

[@dallynsr]

short stroke forced induction high rpms are replacing long stroke big displacement n/a's. better mpgs higher potential hp, less driveline mass, etc etc. already semi-truck power plants size have shrunk, mpgs doubled, and hp's more than doubled. and if the aviation world can do it, cars and boats can do it too. just sayin.

i need this in my GBODY

Amazing video!

[@TheHorsepowerMonster]

Thanks a lot!

[@marconius101]

Cool, my headphones work perfect.. And my ears are bleeding now.. Thank you. xXx

[@alltheboost5363]

Anybody else think the starter was hanging the first time they started it? the other pulls sounded fine.

[@garypeterson9083]

I thought so too. Something didn't sound right.

[@MyersJ2Original]

I think maybe with that much cubes and its first time turning over that the surface tension of the lubes just might have been that tight. Similar if it sat for months.

[@RadDadisRad]

This would be an awesome motor swap for an old BBC motor home.

[@nickg7827]

Ya if ur trying to turn it into the spaceballs motorhome! That thing will move!

[@faridgadimov5955]

Motor home with deleted and tuned 6.7 Cummins engine will be the best option. 10l gas engine on motor home will be 2 3 miles per gallon if lucky

Big block beast.😀

[@KaoticFdr1]

If more airboats were built like this, hurricanes would cease to be an issue.

[@thetezz0001]

A man's engine

[@automech4315]

Just imagine this beast swap on a miata

[@dominiccase6846]

So much torque all it would do is spin the wheels on my wife's Miata or even my 46 Studebaker rodded out.

[@chevydyall7619]

Love the channel and your content mate. Just wondering if we could get some follow up videos to some of the cool builds you feature. Wish it didn't end with the build. Stuff like the V8/V6 land speed engine etc. Do appreciate your hard work

[@TheHorsepowerMonster]

Thanks for the kind words. Following up with some info when the engines actually get into the cars/trucks/boats has been mentioned a couple of times in the comments just recently, and I think it's a good idea. I'm going to see if the engine builders have any photos and will start posting photos in Facebook and Instagram. The V6 SB2 land speed engine made it into the car and all the way out to Bonneville, but because of poor salt conditions it never got a chance to make a run at a record. Thanks for watching!
