- this is a brief look of the tail of two @HolleyPerformance Dominator Carbs. We take a look at the 4575's The original Dominator vs my New @allstatecarburetor built 750 Dominators built for Casper/MIXED UP BOSS
check out the live chat provided by my friend @DragBoss351Cleveland with Mark Campbell the Dominator Carb Father!!!
#holley #nonamenationals
My dad had one back in the early 70s that came from Darryl Armstrong. He had bought his whole A/Econorail dragster. I heard that thing actually flowed around 1350
That is pretty cool! Thanks for watching
Andy
Really need help with some advice on a couple carbs I’m tuning for two totally different engines. I don’t have anyone to learn from around here. Love the videos sir, thank you. I hear a lot about the dominators in RUclips videos and hear they’re great.
I did not know that u could get Dominators buit to "your" specks...!...very cool...!...love the carb videos...u can do alought with holleys..."IF" u know how...!..!...thanks 4 the videos...reguards,Brian
Allstate carbs will build you carbs to fit your needs... I cant wait to get these dialed in once Casper is up and running
Thanks for watching
Andy
It all makes sense now...early 1971... Mopar team experimenting with IR intakes... no platum... and it didn't work...
Thanks Andy!
Good information bro👍👍
Awesome Content Andy
Thanks Brother!
Now I want to put a dominator on my mild small block.
me too!!!!! makes me want to build an engine just so I can use 2 dominators!
Do it have a 1050 on a street car runs great fuel economy as well 20 mpg
Another great video Andy! Love the looks of the Dominator. Can't wait to see what you do with them.
Thanks, I'm going to clean and restore the 4575's and I do want to make a pass with them on Casper just to see what they will do.. lol
Andy
Great vid.
I am enthused at the opportunity to learn your strict tuning methods for economy with these otherwise wild setups and breaking the myth about fi being so superior. Nothing beats a 1050 for tune ability for economy, drive ability, or performance. Mr Campbell, designed them that way.
Carter, You are in luck. Im working on a video that covers many of those items..
Thanks again
Andy
hi andy ,i wouldnt modify the old carbs either there to nice
Yeah I couldn't live with myself... They have too much history!
Andy
I think you made the correct decision. More low-end torque and plenty of airflow. Just my SWAG theorie.
Excellent video showing off the two different generations of dominators
Thanks Jed, I figured while both were on the table I would do a quick comparison video.. things have changed a lot over the years!
@@UnityMotorSportsGarage its very cool seeing all of the differences
Awesome vidja
Thanks Dylan I'm glad you enjoyed it
Andy
I'm going to have to wish you the best and I hope that you have a great evening! Thanks for your history lesson.
You know me Andy, love the Dominator’s. Cool vid, can’t wait to test my 2 sets on something.
I can't wait to see you test them as well! Dominators for Life
Andy
That vintage Holley has to be the most beautiful carburetor that I've ever seen.
Put a ring on it....
.
IR Individual Runner Carburetion on American V8s are extremely rare and extremely tedious to nail down the perfect tune on. Part of that is that none ever saw production and the other part is that when finally so-nailed no amount of cam overlap will cause them to rump-rump idle. Dummies like that, you know.
Thanks for respecting the old prostock carbs!
Yeah, they are only original once! I want to just clean them up and maybe find a Real BOSS 429 Tunnel Ram to display them on!
Andy
The new vrs-4150 has a similar venturi design
I can't wait to get my hands on the new VRS carbs!
Andy
Some stuff does get better. I do like the that you are able to fine tune it.
All I can say that you are about the same as me when it comes to keeping certain things the way that they should be
I suppose carburators will always be misunderstood and if you're a guy who truly understands them you'll always seen like a magician to most people. But it really truly is simple once you learn how they work. I learned the "secret" that's not a secret in aircraft mechanics school in 1990, I'll never forget the day I suddenly had the forehead slap moment in class and I've been a "carb tuning magician" ever since. I'm not special, I just figured it out!
I have looked at dominators since the late 80s but I have never seen one like that 71 model. Its a piece of Art. It would be nice to have a good 750 dominator on hand.
Man I love the look of the '71's but I cant bring myself to modify them to work on my setup.. Hope all is well your way..
Andy
Thanks for the schooling on Dominators, I knew one to see it, but that was the extent of my knowledge. The vintage one is very cool. I think I remember seeing a small cluster of 4 chrome plated velocity stacks being used by some guys on the early carbs, I’ve no idea of the value, useful or just gingerbread.
Nice explanation! I have a pair of the 4575 carbs from 1970. Originally those were designed for NASCAR racing on the Boss 429 single 4bbl manifolds. Later Holley released them to the public.
Carbs have always been a mystery for me!!! I'm not the only one either!!! I know how to take them off and put them on and then I hope they work. I do wish I knew more, but time and money are limiting factors.
Darn, I love an expert... Thanks Andy
J C, I'm far from being expert! I have found that the more I have learned... The more I don't know if that makes sense
Andy
You look like Travis Tedford from the movie little rascals a.k.a. spanky, all grown up. Lol
Wow. I didn't realize that you swapped newer models into use and kept those retro beasts for something else. Someone spent a lot of time finishing and shaping those venturis, they're a work of art. The long boosters and the tall outer venturi sure looks like it would lend itself to IR use, maybe to contain the standoff. They look just like the long boosters and 'chokes' of a Weber DCOE but vertical. You made the right call saving those old pieces of history and using a modern, more adjustable off-the-shelf unit. Plus it made a very good video!
Hey brother I was hoping you could help me with a question if I put an air fuel sensor in the H part of the H pipe on my Mustang will that give me an accurate reading for how the entire engine is running rather than just having it on one side and having no idea if an injector isn’t working properly on the other side until I’ve got holes in my piston
I was thinking of a single dominator, over the six pack set up I have. Stroker 440 around 575hp
This is off subject but......Andy.....I love your t-shirt with callout to vintage Super Stock Magazine! I still have a few copies of those from 1974.
Brian, I Love SSDI magazine... The funny part is the first time I read any of David Vizard's work it was in a '79 issue of SSDI!
Andy
Cool...good info ...both carbs are great maybe better than FI
Smokey Yunick and another gentleman worked side by side to do the finishing touches to what would be known as the legendary Holly dominator carb.
Where was this carb found and bought from I'm located in ohio and have had a my original holley 4575 holley 1050 carb that was on a 451 rb big block rt motor in a mopar race car i stuff got stuff stolen an I've been searching for it ever since thanks kindly
Great info and comparison video!
Thanks for watching! I'm glad you enjoyed it
Andy
Maybe a 427 side oiler is in the future for these carbs.... Andy with a nasty vintage big block
When you were trying to compare 50 years of technological change between the two carburetors. why didn’t you use the Holly XP for comparison “gold standard “
That's a much modified 4575.
great vid. please, please run the vintage carbs on the lower manifold as Independent Runner at the track or on a chassis dyno. i agree wholeheartedly about not modifying them. they are historic artifacts. just disassemble them and clean and dry them out after use. no harm no foul. to my knowledge it would be the only vintage dominator IR testing on youtube.
I think I know the answer, teacher!! Wouldn’t a 750cfm 4500 get better MPG due to a stronger booster signal vs. a 750cfm 4150?
I eagerly await your follow up vid, Dominator’s and MPG is also a sick fantasy of mine
I run a 1050 on a small block it will do 20mpg with ease it's a must to convert to 2ciruit easy enough to tune with a wide band
Hope the truck is coming along well.
Slow but surely... Dealing with a New Milodon leaking $600 oil pan this weekend then its going in the truck!
@@UnityMotorSportsGarage leaking at the weld seam?
@@LeftForDeadGarage yup...
Andy, I know you really love vintage stuff and what you did with the last iteration of Casper truly impressed me. Truthfully you were getting better fuel economy with Casper than I do with a stock 2004 F150. So I have to ask why you stay away from overdrive trannys?
My guess is that it’s a durability issue. But then there are those Gear Vendors overdrive units that supposedly can handle 2,000 horsepower.
Thanks for the info Andy. Any chance of a old vs new dyno shoot out? Not only power and torque results but tuning limits and a pros and cons list?
Would you like to sell the 4575"s and if so, do you have 2? I am restoring one of the Don Carlton Pro Stock cars.
Vance, I do have both email me at tunnelram393w@gmail.com
Thanks
Andy
I noticed right away that you were using modem HP style carbs on the dyno
LIST 1850 - 3 😁 so heavy needs epoxy mod. NASCAR RESTRICTOR PLATE
50 yrs old what does that tell you about how things were made.....have you ever seen a 50yr old computer that still works....not going to happen!... And those carbs will work for another 50yrs!
Funny you should mention that my Atari Pong still woks fine. That said those Carbs were meant for one thing only and that is going fast in a straight line. When Dominators were run in NASCAR they were notorious for running rich and fouling plugs especially at super speedways to the point teams would change spark plugs
@@gullreefclub your Atari pong has never had to live in an engine bay....or under a dash exposed to moisture heat cold....lol😂 it's a dead simple computer.... Try 40 to 60 computer modules of today's cars....hell most pc's don't live more than six years....and their always obsolete when you buy them. But carbs in the right hands are a thing of beauty that you can be passed on to someone else not many things today will last 10 or more yrs.... And yeah I have a Sony trinitron going on 40 yrs still works perfect in a world of planned obsolescence!😥
Theres 50y old computers that work.
They tend to be pretty big though, depending what you call a computer. Microprocessors and home computers were more of a 70s thing. Plenty of 50y old integrated circuits still working though.
There are hobbyists for them, it's interesting. Theres plenty of 40 year old embedded systems that still manage to work, also 40 year old computers tend to not be that complicated to fix(theres a lot more of them than 70s computers)
Also the 50 year old carb here would've needed gasketa and stuff replaced if it were in an engine bay and used for 50 years and was meant to be used for 2 seasons or so.
Vintage computers aren't that different of a hobby than vintage cars, tend to be not so useful for daily productive use though but you have to understand that right now its more like prewar cars would've been in the 70s(not like 50s/60s because the prices are going up like bonkers, a commodore pet is like 1k plus dollars now while at one point you could've had that stuff for free.
@@lasskinn474 I tend to agree with most of what you said....but there plenty of pre war cars that have been upgraded and can serve a purpose as in racing or even a daily driver..... The fault with computers is there over complicated development and throw away nature and there the seeds of obsolescence are planted in modern cars. No user serviceable parts inside! Refer service to qualified personnel only! True prophecy that!!!😁👍
Dont TOUCH that old Dommy.......u'll never see it again..... i think slaghammer is gonna get its ass whooped!!........jus sayin....and i'm a pro UTG dude
Well it's BottleRocket that I'm racing.. it should be good! He is now going to put an Automatic in it..
Andy
@@UnityMotorSportsGarage yea, bottlerocket...sorry, brain-fart......i still think you'll get 'em......wish i knew the combos more, but i've heard bottlerocket run.....it DONT have a big cam or anything......i'd get 'em in my '64 Poncho......Casper, (altho havent heard the motor) sounds like the combo mite be a bit more FIESTY!!!....all good tho, and GREAT stuff u guys put out/do!!!......i am thankful!!...PEACE my brother!!
