i understand the car needs to be set up right for a small inch fe to perform.i guess the original question meant in a well set up car.i guess a better question is how much power can you get out of a 390

Depends on how far you want to go....750 hp not out of the question, but certainly not "street-able".

where is the street-able cut off at 600,650?

Well, that's up to you.  I run 4.56 gears, 28" drag radials and a 4000+ stall converter with license plates.  After we recover from the dragster build, I'd like to do a big inch 11:1 solid roller 393 or 408C with a tunnel ram that needs a mix of 110 race and pump gas.  With license plates.  I don't have a problem with rupp-rupp, no AC, no heat, climb in over the roll cage, wait-until-its-160F-before-you-drive-it, stop every 15~20 miles to cool the trans, 55 MPH max on the highway, etc.  Others may want to hear the radio.

You know that there are licensed,tagged "street cars" that run in the 6's making near 3000 HP.  So there isn't any "streetable cutoff" IMO.  It's what's in your wallet and how much you are willing to do to run it down the road.

+1 on all that.  There is no "streetable" horsepower cutoff in my opinion.  My Galaxie with the big SOHC ran down the road at 65 MPH for hours with no problem, idled at 800 RPM, no cooling issues, no driveability issues, etc.  The only thing was that I would not run it on pump gas at the track, put in race fuel there.  Power adders make it even easier...

i run 4.11 gears 27 inch slicks every day on the street every where i go.but i guess streetable hp has a wide range depending on the person, i guess i was talking about limits of a everyday driver,dependable,long lasting,not what different people are willing to go down the road in.

There are definitely power producing items on an all-out drag race piece that will not drive daily, or even 1200 road miles on a freshen up.....I lean toward using a fairly mild cam on the Drag Week stuff for the extra reliability......you just have to design the head for it. 

I have come to enjoy the concept of building "all you can get" for daily use....and I mean DAILY use.  It is a fun challenge to make reliable, long term power for a driver......

thats what im talking about

[Falcon67]

That's a difference for me.  I have a snooty hot rod at my disposal.  It could be snootier.  But for a daily, I want it to just start and run.  No BS, got no time for that.  Get out of the driveway and get to work.  Heated seats and room in the trunk.  I don't intend to carry groceries stacked around the fuel cell.

The fact that Scott Miller went 2 years on his Drag Week engine, running in the very low 9's, says something about Blairs' ability to get longevity out of your not-so-average "street car". And he may be correct in saying that it's a bit "out there" for a daily driver, but that is over 2000 miles, and when you do half of that in ONE week, that is not to be taken lightly! It's not like running to the grocery store, or out to dinner. We're talking 200-300 miles a DAY of mostly highway and interstate driving, while still being able to cope in bumper to bumper traffic.

You guys are making me jealous with this talk of 650hp cars running 9's. My 463 stroker makes 650hp, I was at track last weekend, and ran low 13's!  Granted I live at 7500 feet above sea level and race at 6200 in a 67 galaxie tipping the scales at 4020 with me in It! I guess I need to move eh?

[Falcon67]

Pulled from here to Hobbs once to run in 7500' DA, never pulled so far to go so slow.  :lol:  Come run that 463 down at the Motorplex and your car may flip over backwards.
