Here's a tip: use an open plenum spacer style gasket underneath that 4 hole. You don't want it flopping in the breeze and eventually tearing off to be ingested by the engine. I use the 4 hole on top to sneak in a 1/4" phenolic between it and the carb to help keep things cool.
Take a look at the Summit carbs. They recently aired an episode of Engine Masters, they compared cheap carbs and compared them to a $800 Holley XP. The Summit did very well, it had the same HP and Torque as the Holley and cost $300.
I can see changing the secondary metering plate to one with removable jets but what about the floats, float bowls, and needle and seats? How are the replacements better than the original Holly 600 parts?
When will you show the rebuild of the Ford 300 inline? I know that there will be some people saying that you already did - but that was on the powernation website, and I can't see it there.
Nice video. Back in the day, Chapstick kept the paper gaskets from sticking and tearing :) The fuel line kit is way over kill for the street. I prefer the metal ones that have a provision for a pressure gauge.
That would be some impressive torque numbers for maybe a 307. Even with 1 5/8 and 1 3/4 headers, that's weak for a 383. Torque is low especially for that HP level. Even kinda low for most modern 350 builds. Somethin ain't right.
Put a extremely fine wire mesh between the intake manifold and carb will make the fuel vaporise better, the problem is to find a fine mesh that doesn't restrict the air flow a lot
It worked on my friends stock 305 quadrajet (low rpm, plenty of support for the mesh). Didn't work on my (at the time) 400ish hp 350 with an open plenum. When we checked, it was just gone! Lol
Fantastic BECAUSE they are less expensive you mean? Certainly not because they work well, especially when they don't make power.. get what you pay for.
VengeanceIzMine no fantastic because they do make power Tons of it In fact when compared side by side to a Holley 850 On my 468 BBC A Proform in stock form produced 24.4 more rear wheel HP than a baker prepped Holley and once I sent the Proform To baker and got it back I had a total of 53.2 more rear wheel horse power than the Holley and since the initial cost was $178 less than the Holley I was already ahead
FlowTech Purple Hornies have been making those glass packs that bolt to the headers for a while I'm surprised Cherry Bomb is just starting to make them that way
You guys are awesome Make it looks amazing and to easy Can you please come to Egypt 🥰 And learn the stupid mechanic what's the mechanical engineer looks like
Doesn't matter much to me, but I both see why it would be a deal breaker, and have only been a Halo Fan for 3 years, so I really don't have an oppinon on the matter.
Carb spacer make me laugh so much.. I’ve seems a couple videos of people trying them on a dyno and never see gains yet you always hear people talking about them.. I guess it’s like the cold air intake in the carb world lmfao
One of the trouble you people have is your making that motor a bigger gas hog. in my day we tryed to build babys that will get just a bit more power with less gas. I dont see that in your shows. try doing one soon.
I was never a big fan of Holley carburetors...always temperamental something going wrong power valve sticking floats not adjusting properly and just overall piss-poor day to day performance... Give me a spread bore Carter AFB any day or even a quadrajet.. I can make either of them for any application and out perform.anything
So reading between the lines, you know nothing about a Holley, and prefer quadrabogs because that's the limit of your knowledge? Everyone is afraid of what they don't understand..
This is funny. If you want a full blown race car you don't need turbos. You can run 8's with a big cubic inch engine on race gass. No turbos or Nitrous.
Mercedes AMG is trying an electric motor on their turbos... www.msn.com/en-us/Autos/enthusiasts/mercedes-amg-is-putting-an-electric-turbocharger-into-production/ar-BB15Cjnm#!
Maybe the timing was the issue...didn't do a vacuum test....This motor is way under...maybe cause you guys are trying to prove that a 600 cmf can work on a 383 stroker.So you took a bunch of timing out to try to prove your point.Sounds like Fake News...
This is bulshit they're just selling parts the second carburetor they just ran it out of the box they would have got the same horsepower if they would jetted it
Used to be a Sunday ritual to watch these with my dad when I was a kid!

Pretty much just turned the carb into a dual feed.
You have to change the bowls because the original bowls had a feed tube front
To rear
Steve Petty is an old friend of mine. He knows his stuff, and he's a heck of a nice guy. I'm proud of his success in racing.

The cherry flavored chapstick was also great for reassembling automatic transmissions without tearing the O rings.
Now install the Jets into the secondary metering block using a Jet tool. Yea ..a screwdriver!
PowerNation is one big infomercial..
LOL
More videos like this, please!!!
Why does the throttle response seem so slow? Watching the throttle cable move vs hearing the rpm, they dont really seem to match that well?
Cause there idiots and loop the same audio for the dyno
It’s the dyno loading the motor. It won’t free rev like cracking the throttle in neutral.

That 383 needs 2" headers and a 650 non choke. You will find the hp goes up even more, and on the end of those headers 3 1/2" collector.

What is the part # to that Holley fuel bowl and metering block conversion kit?
I like the Lancia idea, fit it all and build a badass rally car.
No link for the carb upgrade kit ?
And I love this show
I love how he's using at 1:59 the screwdriver. 😂

What's with that high pitch "pinging" like sound at the end of the runs??? Is that valve train noise? I notice little stuff like that
What about help on an Edelbrock 750 cfm manual choke?
So probably 600cf no power valve sizing or jets front and rear but it's going to run no problem on a 383
You guys should try Proform race series carbs
They are a lot less expensive than a Holley and are fantastic carbs
Fantastic BECAUSE they are less expensive you mean? Certainly not because they work well, especially when they don't make power.. get what you pay for.
VengeanceIzMine no fantastic because they do make power
Tons of it
In fact when compared side by side to a Holley 850
On my 468 BBC
A Proform in stock form produced 24.4 more rear wheel HP than a baker prepped Holley and once I sent the Proform
To baker and got it back I had a total of 53.2 more rear wheel horse power than the Holley and since the initial cost was $178 less than the Holley I was already ahead
How about some part numbers so we know what to get
FlowTech Purple Hornies have been making those glass packs that bolt to the headers for a while I'm surprised Cherry Bomb is just starting to make them that way
Change the secondary canister spring I bet the 770 makes best power.
8:30 the four holes gasket under the spacer?
Is there a parts list in case somebody wanted to try these mods on that 600 ?
outstanding!!!
I prefer Edelbrocks for a daily type of hot rod, Holley is better suited for a race application imo.
It's easy. If you want a race car you use a Holley. If you want reliability and daily driver hot rodding, buy an Edelbrock.
A phenolic spacer would probably still help a little by cooling the carb.
I did that mod in 76 not new
Put a turbo on project stroker stang
I don't understand why you would use an intake with increased hight knowing a carburetor spacer wouldn't have any effect.
He'll yeah
Y'all seen how much those non-stick reusable gaskets cost vs normal ones?
And of course they use new ones on the budget build
Coat your normal gaskets in grease and you can reuse them multiple times.
Just buy the kit.

I added a cold air intake on my '78 302 CID Tbird with variable venturi carb and added a full 0.5 horsepower!
You guys forgot prochargeres
Six horsepower, for how much money ?
Lol
Holley probably makes more money off their Band-Aid fixes than carb sales. All that wasted money for 6hp? Quite the scam for VISUAL EFFECT.

The reason we didn't see any power gains with our spacer, is because spacers are a waste of money.
You must have had the only manifold in existence that was 100% perfect out of the box...
@@vengeanceizmine9878 let's see some dyno sheets for moving a carburetor 1/2" further away from the intake valve.
Those are not street cars in the beginning. Maybe for the trailer queens they are.

@Dennis Massengill Opinions vary...and by Quadrabog I mean junk... even to those of us that CAN tune them. A Holley will always make more power.
@Dennis Massengill Lol, someone knows, trust me on that. Enough to also know when someone's story telling... btw, I got a bridge for sale.
Damn someone done bent thier rim on thier outlaw car 😬
Just buy a 650 dbl pumper
Amish Mike certainly seems right at home with the old carburettor

Carbs way to small for that 383
