He says a Quick fuel 950 is what I need, I'm thinking I'd be a fool not to follow what he says. No? Barry seems really up on things too, and the Quick Fuel 950 seems to play into his "go big" theory too.
While it's obviously not a huge consideration, I just wish the QF carbs weren't so darn ugly. Red? What the heck were they thinking?    |
Dimensionally, all the 950's are the same, QFT is a very good carb though, I havent run one, but I know people who have. Their metering is very good, just make sure you buy one thats made for the intended use. (i.e. buy a street carb if its mostly street, drag if its going to be a drag racer)
Its really not that complicated. Racers were taking a 750 and putting an 850 base on it. It wasnt a tough operation, blend the bottom of the venturis to the larger base and machine a small groove for the idle/transition feed. Then most racers cut the choke tower off to boot
Holley and the rest of the companies started packaging that for them, a little marketing math and then adding a double downleg booster, sometimes smoothed throttle shafts and the HP (or Proform too) shaped carb entry, they called it a 950 "adding up all the improvements"
The 1000's are the same creature, just started with an 850. Throttle shafts are worked, HP body, double downleg boosters and they call it a 1000.
However, a 950="worked 750" and a 1000="worked 850"
You will be fine with the 950, and some guys claim they like it better for the speed the air goes by the boosters, plus, the reality is you wont know the difference anyway if you never run a 1000+. I sure wouldnt go any less carb that that though.
If it were me, because of the dual plane intake, I'd buy the street tuned QFT 1050, but like I said the 950 will run fine, its just a little shy.
