Low 11 high 10 sec all motor setup

I recently purchased my 4th foxbody mustang which happend to be an 89 GT. The car is bone stock with 89k. I have always been a fan of the fast N/A cars, my question is this: How feasible is it to build a low 11/high 10 second all-motor powerplant that is reliable enough to be street driven and "bullit proof"? I am sick of boost problems and oil leaks, looking for a stout street/strip monster, any suggestions?    

you've heard it a millon times"there is no replacement for displacement" size does matter. you want n/a power- go big,cubes that is.a nice stoked and poked 351 that"ll get you 408ci,a nice roller cam,good heads[patriots?]and a decent race intake.  

how about a forged 331 stroker kit with some good aluminum heads and a good valvetrain package designed to rev high enough to make the power to go that fast, throw in a tremec or something, a ford racing driveshaft, some rear gears and you would have a very reliable street strip car, and decent fuel mileage compared to a 408 stroker. and you can still run all your stock accessory drive pulleys. probably cost less to build also.  

I also beleive big cubes is the way to go.I have a very streetable 88 coupe with a 393 that runs low tens as for fuel milage I beleive that would all be in the tune and driving style and as far as price goes there is no cheap build for a bullet proof low 11 high 10 second street car  

well spoken,393. go big or go home'  

i had a 351 bored 40 over with 10.5 compression truck rods & crank with a set of vic jr. heads right out of box comp extreme 550 or so cam cant remem exactly w 750 hp carb vicjr intake bbk longtubes basic mild engine i had c4 with 410 gears good air ran 10.70's humid air 10.80's-90's drove to track/raced drove home sold motor after 4 seasons still like new. long story short excellent combo cheap build  

You could do it even with a stock bore 302, but the combo wouldn't be very street friendly due to the required cam/head/intake specs to make the needed power. I'd recommend doing the 351 based swap instead as it will allow you to be more "street driven friendly" with the components and still have enough power to safely run 10/11's with reliability.  

Not sure that the difference in fuel economy is that significant between a 331 or 347 and a 393 or 408??? Either way (302 base or 351 base) high 10 low 11 ets will not make an economical daily driver. So if I were building a weekend warrior-street terror, I would go stroked 351w. my two cents  

Build the 348" (40 over) w.AFR 185 heads,flat tops,forged ibeam rods,cast steel crank, comp cam 266/274  ex roller cam,edelbrock airgap dual plane intake,long tube 1 5/8 headers.650 /750 holley. Run this w/art carr aod full manuel trans 373/430 rear gears. Depends on how much hwy use.I've run this combo the last 4 years in an 89 conv/high tens/low 11s depending on suspension set up. I used upr complete bolt on kmember kit/coilovers w/3way adj struts.solid rear lowers w/pro series double adj. uppers ,and fms alum shaft,w/flamin rivers manual rack. weight is thine enemy! Very streetable combo.Ran 7.0s in 1/8th. Have now made into full race car w/ets consistant 1.39 60ft,6.70s @ only 6100 rpm shifts.This is a torque monster.Gas mileage should be pretty good w/the aod and 373 gears!  

im also in the same delema.. read my post.... but I have been told by many engine builders that cubes are the way to go... i am thinking of taking my 351w and stroke it to a 408...AFR 225 heads,scat forged crank, and a carb. this will be a weekend warrior.  Besides, building a Camaro killer is worth not worring about fuel milage....LOL  

Hey Guys, Just so you know, the May issue of MM&FF is going to focus on stroker engines. There is going to be a lot of really good tech and editorial on "Bigger is Better" in the engine department and even a buyers guide for stroker engines.

Getting a Fox body Mustang to go well in to the 10s really isn't difficult. The challenge is building a combination that lends itself to street driving as much or more than blasting down the track. The biggest thing to consider  in this situation is how much street driving will you do compared to time on the track.  Your drivability in a car that makes over 500rwhp comes for a few key components. First and foremost is cam selection. When it comes to a cam bigger isn't always better. Once you decide on cylinder heads, displacement, transmission, and rear end gear, the guys at Comp Cams can take all that info and cut a cam that will work equally well on the street and at the track. Second is suspension. With that much power, you're at the point were shocks, springs, and control arm adjustments make huge a difference, so do your research. And another easy way to make a fox fast and streetable is weight reduction. Now I'm not saying go and put fiberglass doors on your daily driver, but there is a lot you can do to reduce weight and in turn, you'll need less power to go as fast. A friend of the magazine has a '92 GT with a 331ci stroker with AFR 185s. He spent a lot of time bringing the weight of the car down and he by no means cut the car up. It is a full street car that gets driven almost daily and it's gone as fast as 11.70 @ 117mph and it only made 354rwhp. Another thing to keep in mind if you're going to build a stroker...  If the car is going to see a lot of street use, you might not want to build the biggest engine you can for the platform (302 = 347, 351 = 468). The larger the strokers put a large amount of stress on wrist pins and piston rings as well as piston sidewalls, and the end result will be more frequent rebuilds over the lifespan of the engine. Also keep in mind the newer "big-bore_ blocks do alleviate some of this issue because you can use a crank with a smaller stroke and still get the desired displacement.

Right now the MM&FF staff is looking into building an N/A motor for a street/strip viper/Z06 killer. All i can say now is that IF the build happens... the displacement will be somewhere north of 430 cubic inches with 10.5:1 compression and it will go in a fox body Mustang.

Its not hard i hav 1 have had it sinc 1988 same 525 H.P to rear axl 351 my Dad and i bilt for it you want to know how E mail Me @ manstang00@hotmail.com                                   P.S myn is a 1979 indy pace car did not know it untill we wer billding the car {my dally driver} im finly thinking about new rings & barings  

Thanks Peter.  I own an 86.  Already stripped the interior, and running only basic equipment to get it to pass inspection.  The car has a 351w that I plan to rebuild into a 408.  C-4 tranny, 3.73 gears, 28x10's with skinnies on the front.  When I say minor street driving, I mean maybe 15-20 miles a weekend.  Hoping to get low 11's high 10's..  

Awesome!  the biggest thing you have to pay attention to to make power is cylinder head and cam selection. If at any point you need some guidance or advice let me know.
