hey i am working on my 83 ford f150 300i6 it isnt ready for the street yet and i was wondering if it has enough power to burn some rubber when i take off

 

I think only the highway geared 300 I6s would have trouble burning rubber on take off.

 

how would i know if mine is "highway geared".

 

My 81 f100 is a three on the tree and I have no problem smoking the tires . I am not sure of the ratio I think it is a 3.08. 2100 rpm at 60mph

 

My 94 2wd F-150 has 3.08 gears and 31x10.50 all terrains on it. It will chirp them around a corner, but to really smoke 'em you have to power brake it.

 

By the way, once you get them rolling by brake standing it---they will burn forever. Like 50-60 feet or more. I have only done it once, because my tires were expensive. And my truck has over 160,000 miles on it and I don't want to break it!

 

Its nice burnin tires in the springtime when theres still sand on the streets from the snow all winter. lots of smoke and pretty mean soundin. For some reason all the small pebbles get stuck in the treads, it when you hit asphault its perfect traction. 3.08 gears even,but all i've done on a higway or something is bark the tires when you hammer it from a stop. Just a whole lotta awful noises, sounds like its gonna blow up!

 

Well I had an '84 and it was very highway geared. The rear end was something like 2.47. It never chirped in its 200,000 mile plus life. Your having an '83 it might be similar. Check the rear end gear. One easy way is count the driveshaft rotations while someone pushes the truck on flat pavement for one rotation of the rear wheel. That is your ratio. If you jack up one wheel only and turn it you will get something maybe like double because of the differential.

My '95 has more power being EFI and has a much lower first gear and a 3.08 rear end, which is probably still considered highway geared. I can chirp them straight line from a roll in first gear, but to really burn them you may have to come off dirt or around the corner.

What about routing the windshield washers back to squirt under the tires? That ought to get them spinning.

 

I have 3.08's and a C6. Stock sized all terains. Can't roast them on dry roads. If there is a little gravel to get them slipping a little bit than i can roast them all day. Black top is the easiest surface to roast your tires on. Or if the roads a little wet, then I can roast them easily, but on dry pavement, not a chance.

I think 2.73s and 3.08s are highway gears. 3.55's are mild.

 

My 75 F-250 has a dana 60 with 4:10 gears and dual rear wheels, also a three on the tree. I can smoke 'em any time I feel like it.

 

Well I left 3 feet of rubber streaks in my concrete driveway today backing out from a dead stop. Wasn't really trying to get rubber, but it happened, probably because reverse is a bit lower than first and because backing up makes it like a front wheel drive without the engine weight over the wheels. What suprised me was both tires left rubber and it is a one-legger rear end. Guess the traction was pretty well balanced.

 

You should have a white sticker on your door jam, you should see an "axle code" listed, get the number then crossreference that to the info in the "articles/specs" section at the top of your screen.

Or just raise the rear end of the truck, count the revolutions of the driveshaft for one revolution of the tire. If you get a 3.** revolution, then that is your ratio :1 and looks like you have a posi rear. If you get something like 1.** revolutions per one revolution of the tire, double that number to get your :1 ratio and looks like you have an open rear end.

 

My 81 F150, 4.9L, T-18 trans, originally had a 2.75 rear end ratio.

It was great on the highway, but a bear here with all of those hils.

I changed it to a 3.50 and glad I did.

It's a good all-around ratio.

As for burning rubber, everytime you burn the tires, it's money out of your pocket.

Wear and tear on your tires, drivetrain and other related stuff.

Yea, it's fun, but at a cost.

I use to burn rubber on my other vehicles, but as for my truck, it's old and tired, but runs good.

 

NOT FAIR!!!! I have a 93 with 3.55 LS (or h9 as i think the axle code is) rear end. Exhaust and intake mods, as well as an electric fan that is hardly ever never totally ever run (IE i rarely use it because all my mileage is from college to interstate 1 mile away, and home 90 miles away). I can not burn the tires to save my life, I just get axle hop out the assssss, I popped a tire off roading 1 time, and when I had the spare on, I couldnt just get them burning for along time, but I could spin them a good bit. Full sized spare (31X10.5) with a m5od tranny. I think its because I have no rear shocks watsoever (they are SHOT!!!) so I load the suspension and then it causes the rear end to jump. Part of me wants to do a burnout to be cool, but the fact that with that loose of a rear suspension I can still barely launch without axle hop is scary. Given that I can break em loose enough to cause axle hop going into 2nd, bark 3rd, and on rare rare occasions, even 4th.... I would hate to see what happens with shocks. I could grab 2nd and have them break loose, AUSOME. Getting new shocks once I win big in online poker. haha.

 

My truck hops too . I have a 79 with blocks in the rear (factory). I want to do a shackle flip and get rid of the blocks.. that'd probly do it. Oh and I'm down one shock too .
