Pretty strong sounding motor there. If the tach is accurate, it runs to over 8K rpm before it begins to float the valves a bit. A lot of time between 7 and 8.... A motor like that could be used in all sorts of racing venues. Whoever built it knew what he was doing.
@@dylanstassen1058 He clearly IS bagging, not only does he only hit with the front, but he quite clearly slams on the brakes before all of his hits. He cant drive for shit.
Holy shit look at all these Facebook engine specialist that act like they know a thing or two because they watch roadkill and work at a quick lube. Haha
Monera96 I agree with your comment, however I dont see 700 ponies there,it takes big $ to get that out of a small block. A 700hp goal is more achievable for less in a 454, 396 , etc for a few thousand. No, I dont believe 700 horse, it wouldnt even make sense. I am somewhat impressed at the almost constant 7000 to even 8000 rpms this engine endured. No, horsies dont matter in mud, unless your mud draggin but thats a whole other story.
Ko-wing wong I realize that, its not a big secret...But what point would it make to put a 1400 horse motor that costs you around twelve grand or more to build, shove it in a herbie derbie car to try to win $1500.00 and destroy it in the process? Respectfully, you're missing my point.....
+6redline3 It don't even sound like a 700hp small block (or anywhere near it). I don't doubt he has a forged bottom end though, as you said 7000-8000 rpm's all that time LOL
There are guys in Australia putting 1500+ HP motors in a burnout car, i don't see the difference. if he wants to spend the money it's his decision. Personally i love the fact that i can enjoy the beautiful sound of raw horsepower while watching a demo derby!
No matter what you do absolutely do not keep the car running if it’s throwing smoke or has any damage what so ever, up here in Vermont what’s hot is el dorados, people go all over the country looking for them to put in our demo, but, they often times just keep revving their motors sitting there stuck not getting anywhere damaging it, nothing breaks my heart more then that, one of the guys last year blew up on him because of this, endlessly revving his engine trying to get out when he obviously could not, no point in it all it gets you is a even more broken car, and with this nice of a engine I’m sure you wouldn’t want that to happen, great job anyway, and good luck 👍🏻
Man you guys are dumb 😂😂 this car has two possibilities 1 destroked 400 sbc to 377 (high rev motor) and 2 ITS A HIGH HORSE POWER MOTOR, no 305 or 350 is going to turn 8 grand (tapping 9) And be damn fine. He will run that motor again no doubt.
Sweet video! I like your 10k rpm sarcasm for the next engine but that would be cool to see if someone had endless funds. Nothing like seeing a vacuum pump, low tension rings, gas ported pistons, and lots of titanium valvetrain in a derby motor!!
with that motor, and carb set up with those headers, you would be lucky if it gave 300hp, even if it had some quality head work.I call B.S. big time B.S
Some Chevy 350 small blocks had as little as 148hp in the smog era. The engine in the video sounds and revs like a 325-350hp engine. 500hp on mud in a rear wheel drive car would be useless.
That could be a 400 bored to 434 you don’t know and that carb could be a 850 cfm plus who knows dude you obviously don’t know shit you can just tell that it sounds healthy asf I mean listen to the lope moron. For all you know he could have 14:1 compression pistions in it and running race gas,e85 or alcohol. Like dude your a moron 1969 z28 camaros with 302s made more than 3 hundred horse.all you have to do is look at the tach in the left bottom and watch the rpms he took it well over 8 thousand a few times and that just tells this is a well build motor with a steel crank rods and pistions, cast shit would have let lose at that rpm. And to note the valve train there was no valve float up in those rpms so that tells you that there’s a good cam and lifter set, roller rockers ,springs and so on. Anyways don’t talk about shit u don’t know punk
Kyle Doll I agree 100% No doubt it's built. Easy 700hp. Listen to rpms and it didn't miss once. I know the sound of a small block and that was 10rpm at one point. The valve covers are tall and narrow so that gives a clue into the valvetrain, connecting it to a gear drive, wise investment.
I agree if you notice the on the Tac it was already redlining at 7,000-8,000 Rpm, and by the sounds of the engine it was not going any higher than that.
700 horsepower my a**!! Sure it revs, but I highly doubt that motor made that much horsepower. I had a 13:1 gear-driven 468" roller motor that was built by a well known NW engine builder whose race motors were legendary, and it was one of his favorite pieces (he even offered to buy it from me when he was done for $10K), and it made 639 horsepower on a dyno stand @ 5800 rpm. I threw a 400 horse Nitrous "Big Shot" plate system on it just for a little extra kick. Manley stainless steel severe duty 2.250" and 1.900" valves, Crower custom ground nitrous roller camshaft, billet stud girdles, micro polished and balanced steel crankshaft, heads had 38 hours of port polishing, bench flowed, cc'd, reworked 1050 Dominator, ect. If his motor was making that kind of power, it must have happened late at night in his dreams.....lol
If you read the description it will tell you that the front axle broke and the wheels kept working against each other so it probably limited what he could really could do with hp
To those of you commenting that it dont "sound" like 700 hp, sound has nothing to do with the amount of power an engine has.........and to those hating I'd love to see your car.......oh wait hard to build a car while spanking it in your moms basement
Doesn't look like there's very many unibody sleds out there. Old solid steel and iron. Do they muddy the pit to create wheelspin? So drivers cannot get traction and speed built up?
Brady Sprague I guess you've never been to a demo derby before.there's only the driver in the car and most generally it would be illegal to hit on the drivers side. Also this car isn't even close to putting out 700 hp.the title was a lie.these cars are lucky to go 10 to May be 15 mph, depending on how wet the track I do take it you're not much for car racing either.no disrespect intended either
Build your front end right and you won't have to worry about that, I hardly ever hit cars in reverse and rarley trashed a radiator because of how hard I built my front ends
Joseph Holcomb A real demolition derby consists of a dirt or tarmac oval and 20+ cars. Last car running or first to cross the finish line in (x) amount of laps wins.
