I was hoping to hear him say something about the results of adding a 10.5 power valve.

I felt the same way. Richard is such a nice guy, but you could tell that he was getting on that guy's nerves from WC. seems very rude Just because your the guru of carburetors doesn't make you any better than anybody else. Treat people the way you want to be treated.

I would pay 100$ for a thorough book on his experience of dyno testing

I doubt if they were ever that cheap.

@@cjbert6790 I installed many on 351 mustangs. They really helped. I also owned a 61 Starliner with a 428 super cobra jet,top loader and 355 posi.

Donald Israel Sounds like a cool car!

I GET THAT A LOT

@@richardholdener1727 lmao. Me too. I must know.

12.8 IS NOT PIG RICH-THAT IS FINE

Single plane manifolds with a big cam struggle to provide a carb with good signal at idle. A four hole spacer should help some. 12.8 at idle is ridiculous, sorry richard. Your running a 3200 stall? So your cam is in the 235@050 range? Your initial should be around 16-18. Need more help, shoot me a reply .

@@GG-rj4oj 230/236 It's actually a XFI Comp listing (08-467-8). Restricting the mechanical timing just to bring up the initial timing, tho putting so much in and making it hard for the starter is also in the back of my mind. How much I have now, I honestly couldn't tell you. I've really only focused on the "all in" up until this point, only because it's never much been an issue until now. I do run the vacuum advance, but is already restricted, which does seem to help, but drops off pretty quick when motor begins to bog when in gear. Sorry for the rambling, just trying to paint the whole picture. Lol Oh yeah, and I'm running a Detroit locker in the rear end, with more internal lash than the law should allow. So That's a huge contributor for maintaining a 750ish RPM idle. 🤦🏻‍♂️

@@n8dawg450r super victor is way to big for that cam engine combo. You would be much better off with a air gap. But if thats what you like, you need a minimum or 14 initial. A four hole spacer will help with carb idle circuit. Make sure your throttle blades are in the correct position. Not too much transition slot exposure. Set mixture screws 1 1/4 turns out and see what its like. Another option you have is to connect your vac advance to full vavuum. This will bump initial timing up and yield a similar result. You can search this, its a common practice.

@@GG-rj4oj I'm currently at about 1 1/2-1 1/4 turns out, and also running manifold vacuum already. Will check and see what initial is set at tomorrow before work. See what's what. Thanx for the input! 👍

Pablo id love to ask you couple questions, if your able to answer would you prefer me emailing you or asking here in this?

@@brianb5779 You can ask here, or if you like I'm on FB at scs performance carburetor/fb.net

@@pablojanski.2559 Thanks alot Pablo. In the past (had a family so ive been out of it for about 5 years and am rusty now) ive done about 6 dominators for street/strip. Meaning drilled and tapped bodies for total control of idle, transition, etc.. Other than 1 ive always converted the 3 circuit carbs to 2 circuit and had very good success. Im helping a buddy now that has 500ci hemi head mopar that just got done w his 1050 quick fuel. It was pig rich so upon starting on it noticed mixture screws were @1/4 turn out on all 4, no transfer slot showing and 1 intermediate bleed at 40 (stock was 80). The ifr was .041" and felt that was way too much so put it at .031". His motor wasnt too far off my 466ci which i had .026" ifr and 46 air bleed which put my afr good at 1.6 turns out on all mixture screws. So my question is 2 parts,,,the first is do you have a particular formula when you size the ifr to the air bleed (i know some feel for every .001" move on the ifr the air bleed should be .006 to .008 change but many times ive seen that not the case). And my next question is do you have a possible thought on initial starting point for the air bleed for me putting it at .031" ifr from the .041".. I already know now his 3rd circuit will need work as well but until i get over to his house. I will be using a a/f meter just so you know. I want to say sorry for long message and hopefully everything made sense but also thank you sir very very much for your time and input.

@@brianb5779 IFR and IAB will have a relative correlation to manifold vacuum and the cams overlap.. bigger cams need more ifr and quicker circuit timing.. fuel used is also important.. generally on dominators to be used on 500+ inch engines with healthy cams that have a good amount of overlap ( ie aprox 5-8 inches hg) you will be in the .035 ifr range and around a 52-58 iab.. turns out on the idle mix isn;t a concern. set those where they are happiest.. concern is the transition.. since transition an idle share the same circuit, going to lean on the ifr can cause lean stumble in the transition.. third circuit can be trimmed right out to as lean as that part of the throttle position likes, but keep check on the wot mixture when trimming the third real lean. Third does add a little fuel at wot via pull over through the discharge tubes.. three way balancing act between ifr third and main.. wot tuning will be hsab, emulsion and jet tuning.

@@pablojanski.2559 Pablo thank you so very much for your time and info. Im in Ohio so if your anywhere close id like to stop by sometime and bring you some thank you gifts

GET THE BRAWLER-THAT VIDEO IS UP

Long story short. You don't need a $900-$1000 XP carb on a mild street car. Now if you had a 496 that liked to turn 6500+..

someone would call PETA on you for torturing cats.

NA you don't squeeze em. You just hold em over the carb and say Spray!

half of engine vacuum when?

@Richard Holdener that's what I'm wondering, their video indicates idle vacuum but wondering how or even if that translates into real world testing.

A properly sized air filter does not affect jetting

@@8power857 yep! thats why i asked what filter would be used in the vehicle. for some reason, people love those fly eye air filters or the teeny 10x1 round filters. they murder hp output.

@@OxBlitzkriegxO im hearing ya!!

@@OxBlitzkriegxO you mean a marine flame arrestor? Cause that's not what they do on carb if you have a backfire lol

@@KingJT80 no, the cheap triangular filters with foam between two mesh areas. theyre cheap and really bad. its nothing like a flame arrestor.

Possibly. No guarantee.

to change load in fueling

@@richardholdener1727 in other words. He went up in the power valve to open sooner with the vacuum signal to richin up the off idle thru mid signal until WOT takes over.

Jesus had long hair because he was under old testament law until his death, berrial and resurrection! Under old testament law Jews couldn't cut their hair or shave their beards. 1 Corinthians 11:14, it's a shame for a man to have long hair... 2 Timothy 2:15, study to show thyself approved... Acts 17:11 study scripture daily... Proverbs 25:2... But I'm definitely not hating on Steve, at all, he's a master of his trade!

I know who you are 😁

@@richardholdener1727 no but I did have the one and only @Nightwrencher on it 😎 almost as good.

Building a SBF 427 for my 67 fastback right now. love when Richard does Ford stuff lol. That did look like a nice lil header burn.

You a v dub man? Guessing here.

@@johnsheetz6639 That, a Porsche or he has an inline 4 or 6.

It's a drill or screw gun. It has the clutch settings

Lol. That isn’t a “rattle gun”. But when you use one everyday like the pro’s, you get a feel for the torque you are applying

I LOVE WHEN PEOPLE DON'T KNOW

Publicly admitting carb tuning ignorance? :)

@@rlovell383 I've tuned hundreds,

@@seancollins9745 what edelbrock?

@@karlsracing8422 you name it, carter, zenith, holley, rochester etc. Carbs, just let them go

I had an Edelbrock on a supercharged 350. It ran great out of the box! I set the idle with a vacuum gauge. Never had to open it.
