Holley 1050 or Quick Fuel 1050
 

I need to put a new carb on a 540. It has a Dart 4500 intake. I have had faw 540's wth Holleys but have never had a Quick Fuel carb. I see good things about them but have a few questions. How are they to tune compared to the Dominator? Do they use the same fuel inlet lines? How is their drivability for those of you that have them on your boats?

If you are getting a 1050 Dominator type carb, this is the one that we use except in 1150 CFM. It should close be bolt on out of the box.

the new holley carbs are nice.i like the quickfuel carbs and have used quite a few of them with good results.i guess it all comes down to what you like.

The new Holleys and quick fuels are very tuneable. If looking for a "marine" carb, holley only offers it in the above carb benperfected mentioned. Its a good carb, but lacking some modern features. Quick fuel, offers a "marine" dominator, with modern features, and the "black diamond" coating, which is very nice. My buddy just purchased a pair of their 850 "marine" carbs, and is happy with them.

Here is the carb Benperfected is talking about

Here is the quick fuel version

I have two of the qft dominators and they are awesome. every orifice that flows fuel can be tuned.

The answer to your question is every aspect of tuning, bolt on parts,accessories, etc.is exactly the same.

Thanks for the info.

What about pro systems carbs ?

not for me!

Just built a customer a pair of 540,s n/a and nickerson dialed in a perfect match as always from my build sheet,you cant beat his price for the set-up..

BeenPerfected - for some reason my little brain thought it remembered you used a Holley Ultra Dominator ?

I curios why? I just ordered one , 1000 on a 4150 base for a 523

The coating is nice on qf, i would say you can tune both, they should be real close on cal's. I use to be a barrygrant dealer years ago and have had some other non holley carbs,Barrygrant then ended up being cheaper than you could retail a holley,.. If there close in price go aftermarket,if holley is a good bit cheaper go for it.

The last carb we did ,we even put in a idle transfer slot jets, so I could tune idle on street blower set up,On my Chevelle runing around town and up to 50mph and is still running off the transfer slots,But its 2 1050's on a 355ci motor

I ran 2 holleys on my Scarab around 7 years, stock 1999 Holley coating held up pretty good.

also you could buy the non marine and make or install your own j tubes

I did because I wanted to use the Gen 3 1150 2-circuit as it isn't offered in the marine version. I bought the J tubes separately to semi make it like the marine version. According to Holley tech, the idle circuits are the same.

Okay, cool. My brain works.

The carb you listed/linked earlier is nothing like yours...not just cfm as you mentioned.

I'm not being a jerk....I'm just making sure the OP knows.

The Ultra's are a hell of a carb...in all versions.

Here is the 1050 Ultra

It had been a while, but aren't the idle circuits were the same?

I also like the tunability of the quickfuels and their tech line guys seem better to me..
