Sure, my 69 Mach 1 with 489" supercharged FE ran a best of 9.35 @ 151 and finished second in class at Drag Week in 2007.  We drove about 1200 miles that week, not counting 400 miles to and from the event.  My 64 Galaxie with 585" naturally aspirated SOHC went 9.50s in 2009 at Drag Week and won the Modified NA class.  We only went about 1000 miles that week.  And my 69 Shelby clone with the 585" naturally aspirated FE has gone a best of 8.88@150, and won Modified NA at Drag Week in 2015, and second place last year, again with about 1000 street miles mixed in during the week.  Oh wait, that's an 8 second street car, not 9 second...   ;D

very nice...let me rephrase the question a bit... using a med or high riser head..sohc is way way out of the budget ... i ran clevelands for years running mid to low 10's.using ported stock heads and stock stroke... i've since sold to fox body and have a 64 fairlane and like to use a fe in it and would like to at least like to match what i ran..just haven't seen very many combo's go that good even with aftermarket heads and strokers.. is it just the nature of the motor

Are you looking to go naturally aspirated, or use a blower or nitrous?  Also, how much does your car weigh?

Scott Miller's 68 Cougar ran 9.20s last year at Drag Week, using Edelbrock Pro Port heads done by Blair Patrick.  Those are basically medium riser castings.  I think Scott's car is about 3200 pounds.  Also, my 69 Mach 1 (3600 pounds with me in it) with a naturally aspirated high riser should run about 9.60, although I haven 't had it to the track with the new engine yet.  Information on that build is at the link below:

Mid-10s naturally aspirated isn't too tough.  My Mach 1 was naturally aspirated in 2005 when it ran 10.60s.  This was a 511" engine with a Comp Xtreme energy street roller cam, Victor intake with Dominator carb, Hooker adjustable race headers, and Edelbrock heads that were ported to flow around 340 cfm on the intake.  Compression was 11.5:1.  The engine made 706 HP at 6400 RPM.

I have a new dyno mule that makes 720 HP, that combination would run mid 10s naturally aspirated in a 3300 pound car, build at this link:

No, but they can be heavy.  You'd think a Mustang would be a light car, but my Mach 1 is 3600 pounds.  Also I'm quoting dyno horsepower, not rear wheel horsepower.  Figure 15%-18% loss in the driveline.

Heck, newer Mustangs are even heavier than the old ones! You'd think with all that plastic, they'd be light...but you'd be wrong ::)

NOT trying to start any debate on dyno numbers, but most dyno numbers are "corrected" numbers, and actual horsepower with humidity and typically higher underhood air temps would also subtract from that number. Altogether, add air filters, power steering, driveline, humidity, air temps etc, and that number can be significantly lower than what a person sees in a controlled environment.

I guess a lot depends on how one defines streetable. I have never driven my 78 Fairmont on the street since I finished it 30 years ago, but it has gone high 9`s, naturally aspirated with very little aftermaket equipment, no roller cam, no aftermarket stroker kit, no aftermarket heads etc. .030" over 427 Ford block, with cast 428 crank, solid flat tappet cam,stock unported  cast iron CJ heads (with original 2.09"/1.66" valves), a 780 vacuum secondary Holley on a 50 year old Ford dual plane intake, a Duraspark distributor from a 76 F250. Lighter than most at 3100 lbs, with a 4 speed trans. Best of 9.97@132mph, shifting at 6200 RPM.  If that too "fancy" the same car with a .030" 428 block, stock cast 428 crank, stock 3/8" rods, same flat tappet cam, intake & carb ran best of 10.03@132 MPH, also shifting at 6200 RPM. The 428 made 518 HP, the 427 a little under 550HP, I guess a fairly well sorted car helps to run OK without a big wallet or a bunch of aftermarket parts. Since my Fairmont only has a roll bar, it is only NHRA legal to run 10.00 ETs or slower, and I am still undecided if I want to make all the changes to make it 9 second compliant, I dropped in my flat top pistoned, pump gas, flat tappet cam 331 SB Ford, which made only 487 HP on the same dyno. Last Sat & Sunday, in 90 degree heat, it was running mid 10.2s @ 128MPH. Big HP numbers are nice, but i will take a well sorted out car with moderate power anyday. JMO
1978 Fairmont,FE 427 with 428 crank, 4 speed Jerico best of 9.972@132.54MPH 1.29 60 foot
1985 Mustang HB 331 SB Ford, 4 speed Jerico, best of 10.29@128 MPH 1.40 60 foot.
1974 F350 race car hauler 390 NP435 4 speed
1959 Ford Meteor 2 dr sedan. 428 Cobra Jet, 4 speed Toploader. 12.54@ 108 MPH

Altogether, add air filters, power steering, driveline, humidity, air temps etc, and that number can be significantly lower than what a person sees in a controlled environment.

Thats very true on the dyno numbers, they are typically corrected to a sea level barometric pressure, and an inlet air temp of 60 degrees Fahrenheit.  As an example, my new dyno mule makes 720 HP corrected, but the correction factor is 6.1%, so the raw horsepower is more like 680. 

But I think weight is a big deal also, given that it is not unusual to see a Fox body Mustang weigh under 3000 pounds with a big block and the driver.  That's 80% of what my Mach 1 weighs, and that car would have run 9s in 2005 if it weighed only 3000 pounds...

Pretty much any of Jay's 500+ CID FE's in a ready-to-run 1,700 lb. Super Gas dragster chassis would be in the 7.75- 7.99 category.  8)

Depends a lot on vehicle weight, for sure!

Look here under drag strip results. 64 falcon tube frame car. Clints car has a 482 that runs 9.60 leaving on a foot brake, c6 trans. Idles at 900 never, overheats, very streetable. Way more in it with a few different parts.
