Has anyone tried a SMI 500 cfm 2 bbl carb from sean murphy? He says they give a money back garnetee if you have another that runs better?

What about Quick fuel's 500 cfm 2 bbl are they any good?

I have used him twice. He has done a good job both times. The latest carb I got about 4 years ago...a 750 HP for my 331. I had it dyno'd along with air/fuel monitoring and the AF was almost right on. I could have left it alone, but I went ahead and up'd the jets by 1 on primary and secondary. I did have to change the PV from a 4.5 to a 7.5 to fix a off idle stumble. Otherwise good to go.

I have a couple of customers who use him for q-jets and 4150's. Both claim better results than their previous carb builders.

Hell, I will take that bet any day of the week. What class do you run and what are the rule's for the carburetor?

Carb has to be a 4412 gage legal they check the ventuirs & throttle plate size

Yep sounds like the same rule's as every other track that run's the 2bbl's. Don't get me wrong, I'm not saying that I'm the best but I do know that my stuff make's real good power. And for somebody to say that they have a money back guarantee, If you have something else that run's better is pretty much saying that they are the best. And I'm sorry I didn't see Dave Braswell's or Mike Laws's name's anywhere.
