I wouldn’t want to go leaning on it and hurting it either.. imagine if it booted a rod out the side of the block (unlikely but can happen and does happen).. the point of this build was to preserve history, not make a million hp... no one sees this!
D G and they nitpick everything they did to death. I promise you not a one of them would of said shit if they were standing there. Just a bunch of assholes that think there shit don't stink for some stupid reason.
All what power? 116 octane with 600 cubic inches and just around 1000 horsepower? A natural pump-gas engine around 600 inches will make 700 ft/lbs at 5k RPM. That Bigfoot engine should be making 1,500 horse easy. I think they went too high of octane and it ran shitty due to low compression- and blower engines run low compression. What are your thoughts on this build- seriously?
@@delljr2769 like I said I'm a Chevy guy... but the technical stuff I dont really know about. So I would be foolish to have much of a discussion about that. The fact is big foot the truck was an icon of my childhood In the early 80s. I bet i could get 1000 hp out of my ls if my checkbook would let me. Lol

@@AgentSmith911 Probably? Maybe? No matter what the truth is, IMO it is very poor production quality to; in Part 2 discuss the importance of the O-Rings, show the machining process, and then show nothing about it in Part 3. You are left with the impression that either they forgot to show it, forgot to do it, or decided against it for some reason. Again, IMO it is shows very poor production quality.
@@L1A1Rocker Bull shit. Just because they didn't mention every little detail that you assumed they'd include, doesn't mean it's overall a bad production. Very few shows have been this detailed in their shows, even Discovery channel can't compete with this. You're just too full of expectations or spoiled or both. Go make your own show.
That was wonderful to hear. I remember my first time seeing this truck and engine combo at the Pontiac Silverdome as a little kid. Nothing compares to this beautiful truck as far as i'm concerned.
I liked his organizer until I remember how often I'm leaning on something and just ONE pen or driver is annoying enough, or when that one specific pen doesn't have the strength to stay clipped when bent over setting a lift arm....no bueno for all day every day techs working on a large variety, me-thinks.
This is an excellent build guide for a technical college training program..I attended such a program through the university of Illinois back in 1968-1969 on gasoline and diesel engines ..every step you see in this video are the same steps that are taken for large industrial engines of all types ..
I’m a die hard Chevy fan. But long live Big Foot. I truly hope it gets a proper resting place for all to see for a long long time. Any man alive can tell you they’ve known that truck from their childhood
My little 5.4 2v with a vmp gen 3 soon to be R makes 787 rear wheel hp 813 lbs of torque at 6200rpm on 23 lbs of boost. 890 ish at the crank. Crazy how technology has come so far. Still wouldn't mind having that big bastard in my engine collection.
I love watching engines being built by people who know what they are doing and care about the end product. Sweet build and some great tricks. Cheers :)

There’s no replacement for displacement. Watching that engine go back together gave me chills. Now do a monster truck budget engine build. Your budget is 50k. Thanks guys, great work.
Ford made more than one of those blocks/heads, but none more iconic than this one! It’s a a shame kids nowadays aren’t watching this and learning monster truck history.

Decent low end torque to move the thing... gotta also keep in mind that it is no longer a 640ci, but maybe around 570ci, because of the smaller bores for strength.. which was a good idea, because when I saw how thin those walls are for a boosted and NOS vehicle, I'm surprised it held together as long as it did overall.

Even NA that motor shoulda been capable of over 1hp per cube and then add over 16+lbs of boost and it should be in the 1300-1400hp range. More than likely it's just an RPM issue. They built a high rpm setup but tested it at low rpm's and even stated it was just gonna be a show piece. Kind of a waste if you ask me.
The whole point of this build wasn’t for big hp anyway, it was to restore and preserve a priceless piece of Motorsport history... they barely tickled this thing on the dyno because... well... would the risk of kicking a rod out the side of that irreplaceable block be one U would be willing to take..?? I do agree to a point that they went abit too “all out” on this thing for what they want to do with it now and in my opinion takes away the originality and nostalgia but hey... when ur as wealthy as bob chandler.. who cares right
I am 8-71 blown away at how little power that thing made. That is Naturally aspirated power when we are talking about the cubic bucks that were poured into that thing. Especially a Kasse build. I get that it was only ran to 5k but I just thought that thing would have put up much bigger numbers.
I loved this 3 part series, but I have to be honest. Bit of a let down in the power department. Sure it lost 68 cubic inches which I'm sure is worth over 100 hp. But I tend to think it's way over cammed for 6500 rpm. Maybe the cam was spec'd for 640 ci rather than 572. IF it made 1000 hp, I suppose that's only about 100-150 hp down on what I'd think it would have made, given I doubt it ever made much more than 1200-1250 hp.
It’s not intended for competition. It’s intended to sound good and make some descent power. Doesn’t need to make 1500+ like most of the monster jam trucks are capable of making. In reality, if thing was built for competition, It would have a hard time not making 1500hp. These Boss 429 platform engines can make in excess of 3000 with the appropriate parts
Wow.. P series Clevite bearings!! Nice to see you using the base crap scrap rebuild series of bearings in this low dollar rebuild. Wouldn't wanna use high quality bearings for such a low end project.
I use to run the Kindig / Predator carbs. Big problem were the fuel bars and no idle circuit but boy they made plenty of horsepower when they kicked in.
Man I really wanted to see Bob's face when the truck fired up for the first time with that rebuild. I invested myself in this 3 video series just for that payoff.
Connor lewis Boost is just a measure of restriction, not CFM’s. It’s only an 8/71 blower on there, not going to make huge power with that. Its only @ 26 degrees of timing as well, 32-34 degrees is about perfect for big block fords. It made 950Hp at 6000rpm, which s plenty for its intended use
ṖauḶee ḂlueṢtreet - I’d like to know exactly how Ford copied anything “mopar” built. I earned my degree in mechanical engineering a while back but I’m sure you have much to teach me ?
640 cid, all new everything, 16 psi boost from a new roots supercharger, triple performance carburetors; all to barely best a stock hellcat engine......... 750 hp from a hemi headed 640 cid engine is a great example of how far we've come.
I’ve been a professional auto tech for nearly 20 years and I own repair shop. Wish I had got involved building motors as a full time job not just a hobby, it’s much more fun and rewarding building engines.
It's a PULLING motor. Torque moves those massive tires. Not horsepower. Low end power, versus high end. Also, that engine was built with a direct port nitrous oxide system. Meaning : that blower engine is built a lot lighter on the scale. Built stouter than ever needed, or tested. The nitrous system, has never been used. Built at a higher compression, without the nitrous thoughts and system ... I'd imagine, your 1000 plus hp number, would be readily seen. You didn't ask, so no offense meant ... just providing more information, as to why the low number.
James Campbell even then, it’s fuck all torque either. They could have made much more torque if they wanted. They’ve either left a lot on the table, or built a very lazy motor. I’m also assuming that the nitros is no little 250 shot.
The torque number is ridiculously low too that engine is very capable of over 1200 hp/tq.... Especially having the best ford engine builder doing all the highly technical machine work. They ended up building a turd od an engine that a na crate engine could laugh at!
Torque at the WHEELS moves the car and that's a function of gearing. This is why horsepower - as a measurement - was invented. If you make very little torque at high revs you move just as well as if you made twice the torque at half the revs. Horsepower is the only measurement that gives any indication of performance cos it factors BOTH torque and revs into the equation meaning gearing doesn't affect it like it does torque. 500hp at 5000rpm vs 500hp at 2500pm just means the high revving engine makes half the torque at the crank at peak horsepower, but it's restored by a gearing advantage for a given road speed, ergo the same "work done" (the definition of horsepower) occurs at the wheels at a given road speed for both engines despite the low rpm one making more torque at the crank - a meaningless figure taken in isolation, but people keep on doing it. Our obsession with low rpm torque is based on the undesirable peakiness of higher revving engines which despite regaining the torque through gearing, are rarely as linear. The CURVE of the power delivery determines how many gears you need. The world's most powerful ship engine in 2013 - Wärtsilä's 109,000 hp RT-flex96C engine - redlines at 102rpm. If we put it in the world's largest truck, and compared it to an engine that redlines at 5000rpm with the same horsepower, that engine might do 200kph with overall gearing of 3:1 (resulting in it's torque being tripled to the wheels as the rpm are reduced to 1666 at the wheel), but the ship motor's gearing to achieve the same speed would be 1:17, hence it's torque would be REDUCED by a factor of 17 due to gearing required to speed the axles up to 17x the measley 100rpm crank speed. But they'd both end up with the SAME TORQUE at the wheels, which are spinning at the same speed, with the same horsepower. So the poor old Wärtsilä''s 7,000,000Nm is slashed to just 412,000Nm at the wheels (meaning the other engine made a measley 135,000Nm or so at the crank at 5000rpm, hardly worth getting out of bed for really) tho with a 2300 tonne engine and what I imagine is a reasonably beefy drivetrain and chassis, it'll need most of the remaining 412,000Nm at the wheels to get up a steep hill. On second thoughts, that's probably still enough. And we thought THIS was a bigblock :)
The only thing I use those red shop towels for is to clean up messes and spills. Then I throw them in the cast iron stove to heat the shop in the winter.
If it’s going to the Smithsonian, I’d honestly rather have seen it on a stand so the entire motor can be viewed. Hell, a junkyard 302 out of a fox body, a bronco, or a host of other fords could have been dropped in for the very few times the truck will ever need to move under it’s own power again.
T J that makes more sense to me also. I figured why not just build a smaller, more efficient and modern big block that looks the part to move BF1 around if they need to and display that original 1980’s work of art so it can be viewed all the way around. Personally I don’t care how old the video is to those who’ve mentioned it in comments, it’s cool to see how they did it in the 80’s. I’d like to have the opportunity to see some old school engine tear downs and builds that are original or period correct recreations.
@@vtwinbuilder3129 nothing has changed today building such engines as the same as the physics of metallurgy will never change and the laws of chemistry and electricity ..the only thing that has changed is our educational programs that teach nothing to you stupid millenials who half of you idiots will think the world is flat ... Lololol
"We know why you came here, to see big numbers on the dyno, so heres a mild tune 5k RPM pull at 750 HP with no nitrous....." Right.......... 3 videos for that........
Exactly What i just thought... Its gonna run a tour then be put in a museum; Why not run it real hard... Almost like they are scared of the work they did.
Ben Moore with only 26 degrees of timing, they aren’t trying to lean on it real hard. Still made 950 @ 6000rpm with is plenty good for its intended purpose. Full competition set up, the boss 429 platform CAN and WILL make north of 3000hp if you want to push it that hard. You could qualify one of the engines in NHRA pro mod if you wanted
Well for one, prolly didn't wanna rag too hard on a freshly put together engine. Another thing, the engine is a piece of history. Would have been a real bitch if they did a hard ass pull and blown it TF apart from some freak accident.
The spark plugs are gapped at 12 thousandths? I knew that you needed a smaller gap and/or higher voltage to deal with higher compression, but I didn't think the gap would get so small.
I like how you signed it. $500 says that Engine never gets taken apart again.
Yup
Maybe in a century or two
No kidding... It's going on display for the rest of it's life. 🤦🏻

I do agree to a point that they went abit too “all out” on this thing for what they want to do with it now and in my opinion takes away the originality and nostalgia but hey... when ur as wealthy as bob chandler.. who cares right
D G yep!..exactly.
*_Awesome Engine...get it back in its home....BIGFOOT #1_*
Great video as always, thanks for posting this
I am 8-71 blown away at how little power that thing made. That is Naturally aspirated power when we are talking about the cubic bucks that were poured into that thing. Especially a Kasse build. I get that it was only ran to 5k but I just thought that thing would have put up much bigger numbers.
Originally the Blower was done by Leo's Superchargers of Manchester, Mo. Leo is still building Superchargers.
Who else is here binging these videos?
loved the video. Thanks for sharing
This should be in the Henry Ford museum instead of the Smithsonian
I loved this 3 part series, but I have to be honest. Bit of a let down in the power department. Sure it lost 68 cubic inches which I'm sure is worth over 100 hp. But I tend to think it's way over cammed for 6500 rpm. Maybe the cam was spec'd for 640 ci rather than 572. IF it made 1000 hp, I suppose that's only about 100-150 hp down on what I'd think it would have made, given I doubt it ever made much more than 1200-1250 hp.
It’s not intended for competition. It’s intended to sound good and make some descent power. Doesn’t need to make 1500+ like most of the monster jam trucks are capable of making. In reality, if thing was built for competition, It would have a hard time not making 1500hp. These Boss 429 platform engines can make in excess of 3000 with the appropriate parts
Road and track said it actually makes 1400 hp. It currently has a crate motor making 800 hp.
That Big foot was built in Chicago Ridge Illinois
Just awesome
Great series guys!
Wow.. P series Clevite bearings!! Nice to see you using the base crap scrap rebuild series of bearings in this low dollar rebuild. Wouldn't wanna use high quality bearings for such a low end project.
Lookin Outstanding Gentlemen.
In these days of super modern high tech engines, I love seeing this old school power plant get a second life.
I use to run the Kindig / Predator carbs.
Big problem were the fuel bars and no idle circuit but boy they made plenty of horsepower when they kicked in.
Man I really wanted to see Bob's face when the truck fired up for the first time with that rebuild. I invested myself in this 3 video series just for that payoff.
Yeah thought they would do some dyno pulls
Hasn’t there already been a video of the motor assembled and running in Bigfoot?
A full race motor rebuilt was very interesting. I would like to see more this. Disappointed you didn’t run it up to full power.
Bradley Griffin probably didn't want to chance blowing it. Let it run full power at the show.
Bradley Griffin It’s not built for competition anymore. Just an updated original. IF it were full race, this thing would surpass 1500hp easily.
Is it just me or is 750 horsepower in a 640 cubic inch engine with 18 pounds of boost at 5,000 rpm not really great at all?
The first time I saw big foot was in the movie take this job and shove it. Big foot had a diesel engine in it that had to be in the mid 70s.
Connor lewis Boost is just a measure of restriction, not CFM’s. It’s only an 8/71 blower on there, not going to make huge power with that. Its only @ 26 degrees of timing as well, 32-34 degrees is about perfect for big block fords. It made 950Hp at 6000rpm, which s plenty for its intended use
Long live the king Bigfoot
Love the sound of that big block Ford
ṖauḶee ḂlueṢtreet - I’d like to know exactly how Ford copied anything “mopar” built. I earned my degree in mechanical engineering a while back but I’m sure you have much to teach me ?
Over .800 lift??? Holy shit!
640 cid, all new everything, 16 psi boost from a new roots supercharger, triple performance carburetors; all to barely best a stock hellcat engine......... 750 hp from a hemi headed 640 cid engine is a great example of how far we've come.
another 2500 rpm it could go.....
Had go back an look at older videos that poor engine went through hell!!!
Great video guys, thank you!
Magnificent! Bigfoot never sounded better, or at least the powerplant.
Coffee filters make for disposable lint free rags
Haven't you heard , you can now buy lint free rags on a roll at auto zone ..they are called shop towels...fuckjng millennial dip stick
I'm learning quite a bit about engines from this.
I’ve been a professional auto tech for nearly 20 years and I own repair shop. Wish I had got involved building motors as a full time job not just a hobby, it’s much more fun and rewarding building engines.
changing tires isnt a tech.ive done clinical research and found 99.87% of people calling themselves "tech" change oil,tires or wash cars.
Bbf with a blower and 3 carbs making 800hp!! WHOA!!! Hold onto you hats fellas. 🙄
Lol my thoughts exactly its like i expected at least 900bhp
It's a PULLING motor. Torque moves those massive tires. Not horsepower. Low end power, versus high end. Also, that engine was built with a direct port nitrous oxide system. Meaning : that blower engine is built a lot lighter on the scale. Built stouter than ever needed, or tested. The nitrous system, has never been used. Built at a higher compression, without the nitrous thoughts and system ... I'd imagine, your 1000 plus hp number, would be readily seen. You didn't ask, so no offense meant ... just providing more information, as to why the low number.
James Campbell even then, it’s fuck all torque either.
They could have made much more torque if they wanted.
They’ve either left a lot on the table, or built a very lazy motor. I’m also assuming that the nitros is no little 250 shot.
The torque number is ridiculously low too that engine is very capable of over 1200 hp/tq.... Especially having the best ford engine builder doing all the highly technical machine work. They ended up building a turd od an engine that a na crate engine could laugh at!
Torque at the WHEELS moves the car and that's a function of gearing. This is why horsepower - as a measurement - was invented. If you make very little torque at high revs you move just as well as if you made twice the torque at half the revs. Horsepower is the only measurement that gives any indication of performance cos it factors BOTH torque and revs into the equation meaning gearing doesn't affect it like it does torque. 500hp at 5000rpm vs 500hp at 2500pm just means the high revving engine makes half the torque at the crank at peak horsepower, but it's restored by a gearing advantage for a given road speed, ergo the same "work done" (the definition of horsepower) occurs at the wheels at a given road speed for both engines despite the low rpm one making more torque at the crank - a meaningless figure taken in isolation, but people keep on doing it.
Our obsession with low rpm torque is based on the undesirable peakiness of higher revving engines which despite regaining the torque through gearing, are rarely as linear. The CURVE of the power delivery determines how many gears you need.
The world's most powerful ship engine in 2013 - Wärtsilä's 109,000 hp RT-flex96C engine - redlines at 102rpm. If we put it in the world's largest truck, and compared it to an engine that redlines at 5000rpm with the same horsepower, that engine might do 200kph with overall gearing of 3:1 (resulting in it's torque being tripled to the wheels as the rpm are reduced to 1666 at the wheel), but the ship motor's gearing to achieve the same speed would be 1:17, hence it's torque would be REDUCED by a factor of 17 due to gearing required to speed the axles up to 17x the measley
100rpm crank speed. But they'd both end up with the SAME TORQUE at the wheels, which are spinning at the same speed, with the same horsepower.
So the poor old Wärtsilä''s 7,000,000Nm is slashed to just 412,000Nm at the wheels (meaning the other engine made a measley 135,000Nm or so at the crank at 5000rpm, hardly worth getting out of bed for really) tho with a 2300 tonne engine and what I imagine is a reasonably beefy drivetrain and chassis, it'll need most of the remaining 412,000Nm at the wheels to get up a steep hill.
On second thoughts, that's probably still enough. And we thought THIS was a bigblock :)
Think you have enough stuff stacked on top of that blower?
The only thing I use those red shop towels for is to clean up messes and spills. Then I throw them in the cast iron stove to heat the shop in the winter.
I have the latest road and track that features Bigfoot one and it now has a 800 hp crate motor but the original v8 is still there.
If it’s going to the Smithsonian, I’d honestly rather have seen it on a stand so the entire motor can be viewed. Hell, a junkyard 302 out of a fox body, a bronco, or a host of other fords could have been dropped in for the very few times the truck will ever need to move under it’s own power again.
This show is from 4 years ago, dummy. Bigfoot's not going anywhere near the Smithsonian.
The engine is now on a stand in Bob Chandlers office. That Bigfoot has a 460 in it now.
T J that makes more sense to me also. I figured why not just build a smaller, more efficient and modern big block that looks the part to move BF1 around if they need to and display that original 1980’s work of art so it can be viewed all the way around. Personally I don’t care how old the video is to those who’ve mentioned it in comments, it’s cool to see how they did it in the 80’s. I’d like to have the opportunity to see some old school engine tear downs and builds that are original or period correct recreations.
@@vtwinbuilder3129 nothing has changed today building such engines as the same as the physics of metallurgy will never change and the laws of chemistry and electricity ..the only thing that has changed is our educational programs that teach nothing to you stupid millenials who half of you idiots will think the world is flat ... Lololol
Dudes rockin one hell of an amish beard
And not a single drop of grease or oil on those hands... amazing.
Outstanding video.
Best in the biz! Great job again guys 🤘
I just came here to see some supercharged big block Ford power.
Those are some monster heads 😳
Such a iconic engine. Great show guys let's make some power
"We know why you came here, to see big numbers on the dyno, so heres a mild tune 5k RPM pull at 750 HP with no nitrous....."
Right.......... 3 videos for that........
Exactly What i just thought... Its gonna run a tour then be put in a museum; Why not run it real hard... Almost like they are scared of the work they did.
Because this show is/was a joke. Hence why it failed
Ben Moore with only 26 degrees of timing, they aren’t trying to lean on it real hard. Still made 950 @ 6000rpm with is plenty good for its intended purpose. Full competition set up, the boss 429 platform CAN and WILL make north of 3000hp if you want to push it that hard. You could qualify one of the engines in NHRA pro mod if you wanted
Well for one, prolly didn't wanna rag too hard on a freshly put together engine. Another thing, the engine is a piece of history. Would have been a real bitch if they did a hard ass pull and blown it TF apart from some freak accident.
Did you see that nitrous plate looks like about a 5000 horsepower fogger..if you , you tube fogger plates you will see what I am talkin' 'bout
The spark plugs are gapped at 12 thousandths? I knew that you needed a smaller gap and/or higher voltage to deal with higher compression, but I didn't think the gap would get so small.
On this episode, guest mechanic Abe Lincoln joins us in the shop.
lol that was the funniest thing i heard all day ty
