I like Cab and others have gone faster every time I went bigger on carbs and the adapter on a 4150 works great IF you fully blend it into the runners/upper plenum...........

oldbracket racer. what's your 20? Springfield, Ohio. Near Dayton. Was going to offer if you ever get up to Quaker City in Salem I'd let you back to back a QF-950 and a Thumper Carbs modified 1050 Dominator. Let me know If your just leaning to a Dominator there are plenty of nice used ones for the taking. Then send it to Thumperdart for some mods..... it will be better than and new Holley out of the box ![thumbs thumbs](/ubbthreads/images/graemlins/custom/thumbs.gif)

Don't think I'll make it there this season though. Probably good advice as far as sending carb to Thumperdart.

What about a pro systems SV1 carb............ We got 1 guy here who runs an SV1 on a 512 in a fr/back halved Dart with a glide and the CC 290@.050/.650" SFT cam, gave up on it when he first bought it but kept with it and is now running pb's at 9.0's with it, one of only a handful of Mopars that we got that runs well.

A better intake will probably get you your tenth even with the 4150 carb. I would still run a Dominator, but as for the 4500 manifold vs. a 4150 manifold w/ an adapter...it all depends. ON THE DYNO a 4500 manifold will almost always make more power, but not always the case as far as performance at the track. Just remember, if you're gonna use a 4150 manifold and run a dominator on it, you have to use the tall (2.25") adapter. Those short 1" adapters are junk.

I am still working on mine, but at the moment, my street car that I was testing it on, has suffered a big engine failure while racing it. My intention was to put it back on and tune as good as I can get it right after the last Nostalgia race I was in when a rod let go. I will be putting it back on for more tuning with an AFR gauge after I rebuild, if it doesn't sell first. Neat carburetors, and I think they take a bit of tuning to get them right. Mine idles and drives great, but I was fighting a rich condition at WOT and partial throttle. Now that I have the G3 1250 Dominator working like EFI, I was going to continue working on the SV1, but it might be a while.

Say it ain't so, carbs can NEVER be as good or near efi............. Fuel disrtibution is fuel distribution correct ![work work](/ubbthreads/images/graemlins/custom/work.gif) The tricks are to get the carbs. to mixed the fuel as good or better than the high pressure EFI injectirs due, correct ![grin grin](/ubbthreads/images/graemlins/custom/grin.gif) Me and you know nothing about doing that, HUH Dominic High pressure injectors will always adimize fuel better.. thats a proven.. it makes the droplets way smaller ![wave wave](/ubbthreads/images/graemlins/custom/wave.gif)

Adimize? Maybe, but I'm not so sure it will atomize better when you use the right boosters. And the biggest differences with a carb is that it mixes the fuel with air continuously, making the mix more homogenous, and the fact that it vaporizes in the intake which lowers induction temps.

Here is some real world experience from days gone by:
Two different times, I bought two different turn key cars that had 1050 Dominators that I thought would be too big.
First one: 69 Dart, warmed up 440, MP .484 cam, 11" OE converter, 3.91's. I SWEAR TO YOU it had an old Torker/adaptor and a 1050 Dom. Ran 11.91 @ 114 mph and I KNEW I could speed it up with my "trick" AED 850 DP. Ummmm, NO. I went to TnT ran the Dom and then changed over. I made several more runs trying different tune ups and the best I could get it to go was 12.02 @ 112, Crazy or what??
Next, a 73 Cuda back half car with a 383. What a odd mish mash of parts that was! TRW domed pistons, R280 roller (!) 2 1/8" primary headers (!!!) 8" converter a 4.86 gear and 14x32 rubber. Intake was a Team G 4500 with a 1050 Dom. It ran 11.19 @ 120 on the Dom and again, knew that carb was too big, so out came that trusty trick AED 850. After throwing jets and squirters at it, the best was 11.28 @ 119.
THEN...a buddy said the Team G was junk and let me try his untouched M1 4150 base. Back to TnT, base line with the 4500 Team G/Dom was right where we left off the previous week; 11.19 @ 120. Switched over to the M1/adaptor/Dom and went 11.09 @ 122.

Just bolt on this little guy. I'm sure it will be great, btw it's for a SB ![smile smile](/ubbthreads/images/graemlins/custom/smile.gif) But wait it has more than 2 circuits, how could it work ![smile smile](/ubbthreads/images/graemlins/custom/smile.gif) As for EFI vs Carb stuff. Look no farther than Pro Stock for an answer. We have a couple of guys in the NA ranks who have tried it and keep coming back to the carbs. FWIW there is a lot more to it than CFM, Venrturi size and basically JUST the carb. Deck height manifold design intended rpm range yada yada yada.. ![](http://i222.photobucket.com/albums/dd105/blowncuda/Mobile%20Uploads/image_zpshg0qcqpu.jpeg)
