QFT HR-600 or BR-600?

[skidd]

For $100, anybody know the difference between the QuickFuel Brawler series BR-600 and HotRod series HR-600?

I was thinking I might call Holley and ask them, but thought I'd start here with you gear-heads 1st.

Currently, I have one of those Summit Racing 600 VacSecondary carbs on my car.

Honestly, it runs really well. Starts easy, drives easy, runs strong.
This carb also happens to run fantastically on my buddies cast-iron head BPE347 in his classic '67 fastback.
Currently an old C4 3-speed, we're doing a T5 swap this spring.
The summit carb runs much better than the plain-jane Holley 4160 he has on there now.

So.. I was thinking I might take a stab at running a good DP on my cobra, while swapping over my summit carb on my buddies car.
I was planning to go with one of these 2 quick-fuel carbs.
But, I can't find any good info on what is the difference between these 2. Other than the $100 price difference.

Any insight or thoughts?

My car is running a stock 302 from a 99 explorer, with GTP heads, weiand stealth intake, 1/2 phenolic spacer, and E303 cam with upgraded springs and stock rockers.
T5z with 3.55 rear gear.

I have a 750 Demon dp on a small block 427 and it runs awesome. I think they are all based off the Holley. A double pumper on a light car like these is the way to go.

I chatted with Summit Racing. Didn't expect they'd know the answer, and they didn't.
Talked to a tech at Holley. And the difference boiled down to 1 main item. 2 different "brands" of carb.
One is branded "Quick Fuel" the other "Brawler". Holley makes them all, brands them as they see fit and picks some arbitrary price.
Other than that, the tech agreed they were borderline identical carbs for the most part...
other than the brawler came with a billet throttle body, the QF comes with a larger squirter.. and I think he said the metering blocks had some subtle difference, but he didn't go into details, and I didn't ask.
so.. I'm going to give the brawler a whirl and see what happens.
