955 Horsepower NASCAR Engine for the Street! (w/ ProMotor Engines)

[@robertreavley7145]

Another great video!! Love this build. It was nice to see the differences in this race motor from a high power street build. Like the shimming of the rockers to save weight on the rocker! To me both engines are great. But for a descent street machine, it would have to be the slightly muted 750Hp. As low down power is better suited for the street! As you wouldn’t be able to hit 3rd gear without getting a ticket!! Gonna watch it again tomorrow incase I missed something. Well worth the wait bud!! Thanks!!

Not high performance, because it's intrinsically a poor design. And typically enough too many people don't have any knowledge of recent engine history. A 90 cubic inch BMW four cylinder racing engine made a reliable 1000hp and up to 1400 hp for qualifying, in the mid 1980s.

Dad laughed inside! He came back after about 2 races, dad said " how did it go" the driver said "man, some of those guys had to sign their name with an X and couldn't read or write, but by god they could build a car and knew how to DRIVE! I never lasted 2 laps!"

This is one of the best Aspirations Index ( AI ) for a naturally aspirated engine ever. 397 times the 8300 rpm power peak, divided by gross peak hp is 3450. The Australian V8 Supercar 305 engines, its 3630. I cant recall exactly the test, but I know for sure one of Richard Holdeners best 5.3 liter destroker LS was 3880, it was some thing like 550 hp at 7000 rpm or 630 hp at 8000 rpm from 305 cubes. A flat head Ford was 221 × 3600/ 85, or 9360. As the AI number drops, you are extracting the most hp from the least rpm. That modified R07 IS a Dynomo!

A lot of the problem is that everything is different than standard engines. Such as they don’t have places for engine mounts because in the race cars they use engine plates. It also gets into race car stuff so the price tends to be high. With plentiful cheap turbo kits a lot of people just go the easy way and throw some turbos at a more standard engine.

[@richardlong6097]

I appreciate them being so considerate and wearing a mask around the engine. Cup motors getting the Rona is a top fear among many of us.

[@PropsandWings]

A food for thought in case no one else figured it out. By moving the camshaft up further, it allows for a reduction in pushrod length and a much more narrow block. Less length means less flex and less flex means more RPM to turn without fear of bending a pushrod. The extra head studs also distort the cylinder walls and change it from a circle to more of an oval shape when it's torqued down. This change can have a major difference in ring sealing and power making plus a reduction in blowby. It's the small things you chase that make a big difference and wether you're 1st or last.

[@VGHCX]

Raising the cam was necessary just because the cam journals are so big. I always wondered why production engines had the cam so low in the block. I thought it should have been raised long ago.

@@bman6198 Horsepoop. Late nights every once in a while old racing shows can be found. I saw one a few months ago, the Talladega 500 from 1974 the fast cars were coming out of the curves at 200 and in the straights could do near 240. If you changed the tires, added windshield wipers and put mufflers on the cars you could have run it on the street. Today's things that run in circles are creations of a corporation, which due to cost, you only have a very few other corporations with the money to field one of those things. Back in the day, if your rig was fast enough to qualify, you were in the field. The things that run in circles today are far slower than the past, and there is no real competition, except in the pits for time-savings. Pretty much a race is won by luck and how quick your pit crew is, not by how well a car is built.

Badass motor. You should get ahold of Dugans Racing Engines in Riverside, CA. They are building 555" motors that are 1100hp designed to go 1000 miles offroad in Trophy Trucks. Similar builders are Kroyer Racing Engines in Las Vegas, Nevada.

Somewhere a tree hugger is apoplectic. The irony is that this engine probably runs cleaner and more efficient than most factory engines.

[@madrew2003]

No way with that much valve overlap. It's a gross polluter by any measure, except maybe at or over peak torque. It's efficient for sure in it's operating range, but don't confuse bsfc with clean tailpipe emissions. NOT the same thing.

[@PistonAvatarGuy]

No catalytic converter, carburetor, huge cam. leaded fuel.... no, buddy, that thing pollutes like a Chinese factory.

@@MrLadysman333 Seriously. The term 'gross polluter' has taken on a completely exaggerated definition today. A whole fleet of these things wouldnt make a dent in any environment.

"Used" parts or not (except for the crank), that's gotta be a $50k motor.

[@c.albrow9161]

says it's $30k on Google.

[@pookysdad4884]

@@c.albrow9161 That actually sounds reasonable, given the exotic parts, and machining involved.

Remarkable piece. The similarities and differences compared to the Ford Trophy Truck build are fascinating.

That’s one Badass motor right there 💪🏼🏁

My god!!! Once that thing creeps up past like 7500, it starts to sound REALLY good!!! 🥰

One of my favorite engine channels! Haven't seen a video with a ro7 yet. Can yall do a vid of the SB2?

[@TheHorsepowerMonster]

Hey thanks! Have you seen my video on Keith Dorton taking an SB2 from Hendrick Motorsports and converting it to a V6 to go land speed racing? kzbin.info/www/bejne/eKS9ZnmKqch7r8k I do want to do a good high-power SB2 build for street/strip use someday, but that's the best I've got right now. Thanks for watching!

Who else wishes they would make a vintage nascar series running the late 80's early 90's cars with conventional small blocks?
