If your carb has a dual pattern base then you can upgrade to a 4500 intake and keep the same carb.

I don't remember your combination so I don't know what makes the most sense for your next step. Having your intake manifold ported might give you more power for example than a carb change. It just depends where the "choke point" in your combo is.

---

No, mine is a single pattern 1050AN Quickfuel Q.

My combo, briefly, is a RB 493 stroker. 11.8:1 CR.
Intake is a Victor that is port matched and massaged a little at the curve under the carb base. 76cc RPM heads . Cam is a Scott Brown grind SFT 259*I/266*E with a 109cl. Lift with 1.6 rockers is around .635" or so.
4 speed, 18 spline transmission, with 4.56 Dana.

Like I said, I'm just going to stick with what I got. I don't see picking up much to justify the cost.
I appreciate all of the replies. You guys are pretty smart.

The biggest difference is in the distribution of fuel, an annular booster provides superior atomization and as a result better distribution. Put the right annular booster on a large 4150 and the difference will only depend if the engine can use the larger carb. There is an option in between...

Ok, I'll ask, what carb is this and what is the advantage of using this carb instead of switching over to a dominator?

The Victor is kind of small for a 500 inch race motor so if you want to throw some money at the motor I'd start with a Super Victor if you have the room under the hood. Use an adapter to keep the 4150 carb. Other thing you can do is put some 1.70 rockers on the intake. You are probably curtain limited with that cam on that engine.

---

This cam has worked very well for me. It was originally in my stock stroke engine. Scott Brown told me back then that he liked to stay on the smaller side with cams. At that time I was running a MP 590. My best time was a 12.00 @ 114. After installing the Scotty cam, I was consistently in the 11.70 range at 118 mph. In the past I've tried larger cams in the stock stroke motor, but slowed down. You may be right with the larger engine. Maybe a little larger cam may be in order. Something like 265/270 with about the same lift. .635"-.640" on a 108 CL.

I think that one of BLP's specials called a Little Bo, and I'd guess is for when your class doesn't allow 4500-type carbs, but you need to be able to give the combination more airflow than a typical 4150 can provide.

What confuses me is that I saw this one on their web site today, something they call a Weekend Warrior. Those venturi look pretty big, kind of like a Mini HP Dominator body on a 4150 base plate, and they say it's only a 750???

...I have 1.45 and 1.59 venturi bodies here if anyone is interested, and can configure either with down leg or annular boosters.

---

Tempting, but I have yet to test the last one (QF "1000" 1.52" v w/ BLP-modified downlegs) you built for me.

Thanks for the offer Gus, I appreciate it. I've been running a 1050AN Quickfuel for several years and I'm real pleased with the results. I was just wondering if there would be any worthwhile gains buy going with a Dominator set up. Unless used parts are used, you are looking at over $1K for intake and carb. For that kind of money,I'd want a substantial gain.
The way I'm leaning now, based on the way I drive my car, I'll just keep what I got. Having a 10 second 3900 lb. street car is something to be proud of, at least in my eyes.

---

I've been running the same setup since 2010 with 1050 main body.

See this post: https://board.moparts.org/ubbthreads/show...part=1&vc=1

I like the 4150 series carb cuz you can use a stock oval air cleaner in "stealth mode" noone is the wiser as to what you've got under it.

I noticed you have the same MPH I do but you are a few tenths slower than I am. So you're making big power for a street car. Our combinations are similar. Same size motor and similar compression (I'm a little less). I have 4.30s and you have 4.56s. Same body style and weight. The only significant difference I see is I run a 727 vs your 4 spd. Perhaps the quickness you're looking for isn't in the carb? What's your 60'? What are your incrementals? It might be a simple fix like shocks or air pressure. Before you spend a grand a carb you may not need, I'd look at your combo. You are definitely making enough power to go quicker.

I have a monster cncd big 4150 And it made 19hp less
then an sv1 RyanJ had a few yrs ago.
This was pretty much 6 pulls or So on each.

I realize that my 60' times are slow. I purposely spin the tires a little rather than dumping the clutch or slipping the clutch. I'm usually around a 1.55- 1.59. 1/8 mile is around 7.1-7.2 at just around 98-99 mph. It pulls hard in 4th gear showing almost 25 mph increase from the 1/8. My best 60' was a 1.50 at Columbus last year. Currently my 2 step is usually on 48-5200. If I come out higher, my 60's will drop, but I don't feel comfortable going much higher than 5200. I'd like to be able to drop my 1/8 mile times, but with my current combo, I can't see that happening.
I realize that the first 1/2 of the track for me is kind of slow, but it is what it is I guess....

---

You definitely have mid 10 second MPH and a nice car. Agreed, it's tough with a stock style 4 speed and you're doing better than I could ever do with mine (my car is also originally a 4 speed car).

Could the additional flow be attributed to the intake, seeing as how both style carbs are rated at the same flow number???

---

There are so many factors, when running a Dom, you are usually increasing plenum volume so unless your adding volume under a 4150, its just not cut and dry answer. Even the same exact intake will have different characteristics. One opened up for a Dom may now have shorter runner lenght and bigger plenum and the engine may or may not like that

---

On a dyno, the bigger 4500 manifold and dominator carb will almost always make the most power. What runs the fastest at the track may be a different story. Have to be careful w/ manifold volume on a street/strip car. Too much and it'll really hurt the lowend grunt and the little you gain up top will never make up for it. Even my big 572" hemi was really hurt by the larger Indy 426-4 single 4500 manifold versus the Ray Barton single 4500 manifold I had run before. Ran great on the back half, but lost so much in the 60' it was still a tenth off. If I loosened up the converter more, added more gear, more spring pressure for the added rpm, I may have been able to use it...but that's not what I wanted at all.

Ever notice a lot of people run the 4150 Indy manifold w/ a 4500 adapter instead of the 4500 Indy manifold? Only problem w/ using the adapter is it's really tall. The short ones don't work well.

Only way to know is to try one and see, but that's an expensive test. Unless of course you borrow a carb from someone. I'd suggest an adapter for the dominator for your current manifold...if you can fit it.
