87-93 Stock Longblock 5.0L -Recipe-

[Pure Stock]

Getting a 5.0L into the coveted 12 sec e.t. is not as hard as it may seem. To attain sub-13 sec. e.t.s start with a 5-speed version of the 5.0L. Mix in a lightweight version (coupe), well thought out bolt-ons, traction e.g. slicks, and aggressive driving.

I have compiled a list based on facts, not generalizations and assumptions that has the potential to propel a stock long-blocked fox body into the 12's. A good tune is paramount in the quest to reach this goal.

- 26 x 8.5 x 15 slicks (can mount on turbines/10 holes and retain quad shock)

- 3.73, 4.10, 4.30 gear (select ratio depending upon tire height selection)

- Headers (long tubes>short tubes)

- Off road H or X (may need to replace to pass emissions test where applicable)

- Under-drive pulleys (may eliminate need for these if serpentine belt is eliminated, use caution if employing this mod and use at track only)

- Eliminate factory air silencer

- At a mininum use a K&N panel replacement filter

- Stock T.B. and M.A.F. will work. (track testing showed no loss of e.t. or gain in MPH when switching M.A.F. -same day testing-

- Remove front sway bar (helps with weight transfer)

- Remove stock clutch fan (*if* using underdrives)

- Short-belt (*if* underdrives are used)

- Advance timing (13-14 degrees is a good start)

- Adjustable fuel pressure regulator

- Remove unwanted weight ( you be the judge, what do you want to eliminate, *remember these small c.i.d. engines do not like to lug weight, removing approx. 100 lbs. of weight nets a mph increase)

- Practice, practice, and more practice. (If you are afraid to break something your leaving precious e.t. on the table)

Some additional mods to consider:

1. Synthetic lubricants throughout
2. Aftermarket rear control arms
3. Sub-frame connectors
4. Increasing air pressure in front tires to decrease rolling resistance
5. Aftermarket shifter
6. Battery relocated to rear of hatch/trunk
7. Air bag in passenger rear coil
8. Light weight wheels
9. Ice upper plenum (gains of 6-8 H.P. here -dyno tested-)

Mods that produce minimal gains if any:

1. off-the-shelf chips
2. aftermarket ignitions including expensive spark plugs
3. bigger injectors (contrary to popular belief upgrading injectors will *not* produce more power)

CAN WE MAKE THIS A STICKY?

i have a buddy who had a stock long block with the old edlebrock 5.0 intake bbk cold air elec fan and timing at 14* and 3:73, with weld draglite skinnys on the front 26 x 8.5 on 10 holes rear full weight 88 gt nothing removed at all 13.18 @ 106 to 107 it had approx 170,000 miles on it kept minimal oil pressure im talking 10lbs when hot idle

[fastfox91]

this is the car i was talking about it actully has welds with et streets on them and heads on it in these pics. with trickflows tw's bolted on it ran 12.8@ 109 almost 110 on i think mid 1.7 60fts

[George C]

i can verify some as well. i went 13.38 @ 101.8 in my 88 notch

also remember its not how high of an RPM you shift at its where the car starts to drop off at. i was shifting at 4500 rpms yes 4500 rpms and netted my best times. i never lifted off the throttle either and didnt lose hardly any rpms between shifts. if you want to go fast you must trash the crap out of the car. I had K&N panel, OR H pipe, flows with no tails, 355s and worn QTPs. timing was at 10* with a 153k on the car at full weight. so its very easy to get good times out of these cars if yoru aggressive.

a cheap but yet effective way to help with driveline loss % is to use straps to strap the motor and trans down. if you have good motor/trans mounts this isnt a problem but on most highmileage cars the mounts are shot. i had used rachet straps to help tie the motor/trans down which help put the most power down to the ground

How is it a stock longblock with an aftermarket intake?

[fastfox91]

i consider a long block heads down sorry i consider a short block to be no head just block and rotating assembly anyway with the stock intake it went 13.29 so there wasnt much of a change i think mph went from 109.6 to 109.8

How is it a stock longblock with an aftermarket intake?

Block, internals & heads. Manifolds dont count.

[fastfox91]

my 91 gt at full weight went 12.73 at 110.7 with a 1.71 60ft with just 4:10 o/r h and flows with 75 shot. its best on the motor was 13.98 at 103.1. it just wouldnt pull 60ft on motor its best was like a 1.97 those passes were all on 26x10 m/t on hurricanes rear and ponies on the front

So let me understand, you had a stock longblock including stock intake goin' 109.6 mph and you changed the intake and gained .02 mph? Is this with the 75 shot?

[fastfox91]

my best ever was 110.73 with the 75 shot but it only did it once all the rest were in the 109 area
