6.90s (or better)single carb, NA, who's done it with a BBF?

Post  Mustang-junky on March 23rd 2015, 9:28 pm

The fella in this story seems to think that going BBC is the best way to get it done. Knowing that BBF's are often underrated, I thought I would ask.

Quote from Alex Hays ..."I'd love to see a big block ford run 6.90s at 3350 lbs naturally aspirated with 1 carb"

I figured someone here knew how to do it with a BBF.

Looks like about 2000HP for that 6.9ET at 205MPH. I like to see any N/A V-8 do that. Did you mean 7.9?

You do know his car runs 7.90's with the BBC not 6.90's don't you?His "I'd love to see a BBF run 6.90's N/A with 1 carb at 3350 lbs." i think was a response to the one guy saying his BBF was a second faster.

Back in the days when ProStockers were running 6.90's....they were N/A...but they damn sure didn't do it with one carb, and they damn sure didn't weigh 3350 lbs, either. Pick your brand, that's a pretty tall order.

Who's done it with a GM or Chrysler?

Seems to me this is a loaded question.....

An 825" Ford Hemi mountain motor will get you damn close but it needs more air than a single 4 will give.

Edit..... Shoot a C460 headed 600" engine will do everything that the Chevy engine in that car is doing.... Why poison the car????

You're talking about a Pro Stock type engine that will rev high enough using one big carburetor ... if nobody has done this with a big block Ford it is simply because they haven't wanted to or needed to.

It won't take 2000 horsepower to run that fast with a 2,500 pound car.  NHRA Pro Stock cars are in the mid sixes with much less; 3,500 pounds today is a tall order for ANY brand including Allison or Rolls Royce well over 1,000 cubic inches.

the car in question weighs 3350 and I too think it could be done with a C-headed 600 inch engine

My point, though really not clarified, was to work on the CAR and get some weight out of it first.

I misunderstood what he was trying to say. I thought he was running 6.90's, makes more sense now.

It's is car, he can do what he wan't with it. And I see the junkyard turbo LS motor deal, go fast for cheep. But, if you are going all aftermarket for the motor, why not run a BBF?

His car ran a high 7.90 last year IIRC at a Milan Michigan race.Butch Kemp with his SBF Mustang has ran 7.70 's or 7.80's at the same track IIRC.

Thats what the Wallace Cac. said anyway at 3350lbs. It was between 1800HP-2000HP with a 6.9ET and a 205MPH trap speed, forget which way, so I picked the bigger number.
