Burnin rubber

[Boardrider52]

ok this is kinda making me a little mad i have a 72 Jimmy w/ estimated 315 hp and i can't do a freakin break stand. any suggestions why i can't do one?

[Longhorn Man]

crappy gears.
I have quite a bit of power, but I have to try to turn the right rear on mine.

[bigjimzlll]

it takes a litlle more horse power than people think to roast the hides..an inexpensive way of doing it is to add a line-loc...under 100.00...it allows you to lock only the front breaks...other ways(besides making more Horse power) lower gears(higher numerical) a higher stall converter..shorter rear tires

[68CST327]

Sorry, can't be of much help... check to the left under my name, quite explanatory. I will say that bigjimzlll is right, it takes more horsepower than most people realize.

I have 31" x 9.5" meats on my C20, and with the 3/4 ton drivetrain, and stock 327, it's a complete PITA trying to get the tires to break loose. Even when I power brake it, they just spin a little bit, and it doesn't lay down any rubber or smoke at all. Pathetic.

I think my main problem is horsepower. I just need to make alot more. I'm thinking new heads and cam should be at the top of my list. Anyone know what a stock '68 327 makes in HP?

Jeez, I feel sorry for you guys. Nothin done to my truck except a rebuild and HEI, and I can do an excellent power brake burnout. Heres my intruction list:

1). Find first gear (I have an SM465). This may take a while to do.
2). Dump clutch, hold brakes & gas.
3). Cough at the intense fumes.
4). Repeat as many times as necessary.

And there is an optional bonus step:

5). Laugh at your friends in their ricers who try to lay a patch but just chirp the tires.

[68CST327]

Yeah, but it's easier to do with a manual tranny!

[1969 GMC]

Can't you select a low gear on automatic trannies, like
P R N D 2 1? I'd think that'd work. If not...buy a stick shift, lol.

[68CST327]

Sure, you can select a gear, but you can't dump the clutch. Makes a huge difference.

[bigjimzlll]

also the 1st gear on a sm465 is like 5 to 1..while an automatics 1st gear is 2.5-1...try doing the burn out in 2nd gear with a sm465..thats what its like with the auto..oh yeah dont dump the clutch

[Gee_Emm]

Park on some gravel or hose down the pavement :p

i have to disagree with most of ya'll about the amount of horsepower. in my dakota, i can roast them from a standstill, or power braking. of coarse, it is a stock r/t, 250 horses, 345 ft/lbs of torque. you have to have torque to push these bricks down the road, otherwise, you can have as much horsepower as you wish, but you won't go anywhere without torque.

[bigjimzlll]

actually 250 real HP and 345ftlbs of real torque would be enuff to do it...but in the real world, most dont have that much

[nightmare]

are you talking 'bout at the rear wheels? those numbers that i quoted are from the engine alone. i'm not sure what the bwhp is on the dakota r/t, never took it to the dyno.

[bigjimzlll]

some of the HP ratings for a 350 were below 200HP..and if the engine is tired, with a new intake and carb+ headers..its not a whole lot more than that. That and the fact that are chevys have the best rear suspension, and hook fairly well

[nightmare]

i agree that the chevy's have the best rear suspension. i'll have to see what mine does when i get done putting it together.

[Long Knight]

Here's what you do: Log chain the rear to a BIG tree, preferably dense hardwood like oak. Put a half quart of motor oil under each rear rubber and hit it! Recommend gas mask if you have sensitive eyes or lungs! LOL

[crazy4chevs]

you might want to take the slack out of the chain before you floor it!

[Long Knight]

Oooo...I, forgot to mention that. LOL!!

[Smooth68]

pickup an old windsheild washer bottle and pump, run the spray hoses back to just in front of your rear tires. When you want to smoke'em just give it a spray and press the pedal.

[73stepside]

my camaro is only rated at 170 bhp and i can brake stand that all day. my truck has way more power and haven't tried the brake stand yet....don't trust my carrier bearing. but it will break loose at half throttle on dry pavement at a stand still.

[bigjimzlll]

I just did a little burn out..took the slicks off and put the 295-60-15s on...I let off at 100 yards. I was in third by 60 feet..the neighbors are'nt very happy...lol..

[sgtjed]

i feel your pain,i have a healthy,non stock,327/350 in my truck with 3:73 gears in the back. all i get out of it is a chirp when i floor it. now my 97 z/28 6spd will lay all the rubber ya want all the way into 4th gear. so if i want to throw down some rubber i hop in the camaro,but if i want to thump around and smoke the same camaros like mine i hop in the truck cause as they are busy trying to get traction i am down the road before they hook.

[mikep]

A higher stall converter would help a lot . So would lower gears. Remember truck tires are a lot taller than passenger car tires so a typical 4.10 geared truck rear end would be the equivalent of a 3.31 or 3.54 under a camaro. Yet at the same time your'e trying to push another 1000 lbs down the road. Its the man conspiring to hold you down!

I figure I can get 50-70 yards of rubber stuck to the road off both rear tires before I get bored. 4.57's are sweet !

[Boardrider52]

oh yeah i forgot to mention that that i have 33 X 12.5in Muds

My truck has no problem spinning if i get it sideways, and it will do a GREAT burnout if i powerbrake it, but if i am stopped and simply mash on it, it won't even turn over a tire. It has a fairly fresh 350 with about 275 hp and 375 tq, TH350, and 3.07 one-legger gears. The 255x50-15 tires i have right now won't spin from a dead stop w/o powerbrakeing, but the old 235x75-15 would spin for about 15 feet in the same situations. I think the coil springs help plant the power to the ground pretty good. Also, if you have positraction or a locker, it obvisouly won't spin near as good as a open diff. Which is good if you wanna go somewhere instead of make smoke .
