i have a 302 in my f-150 its a long bed and it wont power brake..do i need line lock or just more torque?

Question

its an automatic, when i get into a power brake it just revs high and when i let the brake out it spins them a bit.

Answer 1

line-lock are you joking? if that thing is so stock that it won't spin the tires. you need to spend your money on some horsepower before worrying about a line-lock.. get a nitrous kit & a 4.10 gear and you will need tires every two weeks. and for someone to say that power braking is brake pedal finesse is just an admission of how much they don't know. if you have horsepower you can do a 3 gear burnout if you so choose. and you could set the timing at 40 degrees advance on a no power engine, it still isn't gonna do it. and for the love of god don't try & lean over a running vehicle in gear at full throttle the next step would be the emergency room.

Answer 2

If you have enough motor, you can stand on the brakes and stomp the gas and need a set of tires in short order. The two easiest ways to get to that are a big motor and/or some gears. If your gear ratio is too high, you may not even be able to do it with a big motor. You can check it, there should be a tag on one of the bolts holding the third member in or the cover on. If it's 3.00 or higher, look for some gears. Manual trans trucks usually have lower gears, if you want to crawl the junkyards. You didn't say what year the truck was, or if you live somewhere with emissions laws that would make an engine swap difficult, but a junkyard 460 with headers and some 3.50 gears should move that rig nicely.

Answer 3

To get a vehicle to powerbrake requires a great deal of finesse on the brake pedal.
What your trying to do is hold enough pressure on the front brakes while not applying any pressure on the rear brakes.
All vehicle's are built with a proportioning valve in the brake system to apply pressure to the front brakes first and gradually apply pressure to the rear brakes.
If it didn't the vehicle would lose control.
To get your truck to power brake start with water under both rear tires to get them to break lose easier.
You will then learn slowly how much pressure is required on the brake pedal to really smoke the tires keeping the front brakes enaged and the rear brakes free.(Make sure it is low gear and keep it there)

More motor will definitely help but you should be able to do it with the 302 if it's running properly.

Answer 4

You need to sit In the truck holding the brake while giving It throttle and have someone standing aside the car rotating the distributor cap for better timing. That should solve your problem. Don't set It to high cause your motor will ping at higher revs. If Its a 5.0, you should be safe using a timing gun and setting your timing at 16-17. 93 Octane advisable.

Answer 5

the stock 302 doesn't develope enough torque on a long bed and your going to need to replace the u-joints once your able to generate enough power to a heavier duty U-joint.

Answer 6

if you want to play these games and not destroy your rear brakes and transmission then get a line lock , might as well learn to drift too

Answer 7

you need more engine
