i have an 82' z28 with a 305 and 3 spd automatic, a friend of mine has an 85' z28 with a 305 and 5 spd standard, both of us can't seem to be able to lay a nice clean burnout, now the driver can only be one part of the problem (especially in an automatic), my question is should a 305, ehich is pretty much stock, be able to lay rubber? any comments would be appreciated because i'm soon going to be doing a tranni change to a 5 spd manual because my trani's starting to slip and i'd kinda like to know if that will help my performance out a bit

sure, you can lay some rubber...powerbrake it haha, but no, i have a stock 305 with a 3 spd plus o.d. trans, and i cannot get it to lay out rubber jsut by flooring it, i'm sure if you did some nice mods to it, you could or you could just build a 350 for it...that would certainly get the tires i'm sure...maybe an lsx?

Throw some oil on the ground and that should cure the o'le 305's esteem issues.

i like that one...that might work on ricers too! i knew this guy who used to have a suped up 88 t/a with a 305, said he used to beat vettes, stock of course, but i think hes full of crap...cuz i cannot see my car beating anew vette anytime soon, no matter what, especially how he didnt seem to have many mods on his

rocluvr0013

a 305 tpi car in good running condition should have no problem laying rubber. Even my friends 86 (peanut cammed) auto equipped car smoked the hides from a stop.

netfreak

I'm kind of curious about this topic. I have a 305 TBI stock cams/heads and if I punch it from a stop it leaves a long patch of rubber (albeit one side ). It even chirps second when doing this. I can also get the rear end to slip if I punch it around a corner.

All in the gearing LOL some had 3.73's/3.42/3.08's maybe the ones that can't have 3.08's.I was going to say just do spinouts on ice but didn't want them to skid off into oblivion is all .....

seen tree oh fives that put out just as good if not better than a 350, build it right, plus when you wax someone and they ask what you got just smile and say its just a 305 also a bad azz 305 is diffrent, its almost like being a rebel LOL............im planing to stroke a 305 when i get some extra time/$$$$ will post what happens......Notice to the left there i got a 305 that barks the tires going into 2nd (700R4 not a 5 speed) with 2.73 and TBI and do a great burn out not PBing ....but its not stock

darkride86T/A

My 86 T/A has an LG4 305 and 700R4. The only thing done to it
is an intake and exhaust. My current 700r4 is garbage and the motor's
got 199,000 miles on it. On a good day, even with the limp-wristed
P/U truck 700r4 cutting loose between the 1-2 and 2-3 shifts, the old bird
will lay down 10-15ft of rubber. Granted it is a peg leg burnout, but I can do it from a standstill w/o power braking and she's got 2.73's gears!
My car wouldn't do it with 245/50-16's, but I could smoke 215/65-15's right off of the hoops.

fast355 did you abandon TBI ???????

Fast355

iTrader: (2)

NO, I abondoned TPI and the 305 in the Van. Went to a TBI 350.

Jproz1167

iTrader: (3)

fast355 can a 7747 run a 4.3 TBI v-6? and what kind of chip would be well suited for it with vats and full emmisions?

Fast355

iTrader: (2)

The 7747 was the factory ECM for thousands of 4.3 engines. Look in the 1988-1992 astro/safar van and fullsize vans with the 4.3. Most of the S-series trucks had ECMs that were coded different than the 7747. The 7747 does not use VATs. VATs is simply a module that inputs a signal into an ECM such as the 8746 to turn on the fuel flow from the injectors. If the ECM does not require the signal, you don't need to worry about VATs.

Jproz1167

iTrader: (3)

so if I just swap a 4.3 chip into my v-8 7747 I can still retain my vats. this is a camaro ecm by the way

CLC85TA

On my carbed 305 before I pulled it, I was able to powerbrake in 2nd gear with a T5 behind it, 3.27 gears, and it spun both. Lots of smoke from the 235's.... Was never able to click 3rd though.

Hammertime540

TPI, carb, and well tuned TBI should put some impressive rubber down. I went from TBI to holley 650 double pumper, I don't leave any rubber on concrete without using the brake. But on black top roads I can punch the gas from dead stop and roast the tires as long as I want. I've had a hard time getting traction at the strip with stock tires. They squeal a bit off the starting line, but I think my locker is worn out.

iTrader: (8)

Depends. If you consider 16 second stock 1/4 miles ballsy, they have *****. LOL. Regardless, even my LG4 305 will power brake (but then again, power braking shouldn't take too much HP)

blimko

iTrader: (1)

well idk what some of you guys are talkin about cuz my 89 maro 305 tbi 5 speed rips tires all over the place. its basically stock. im pretty sure i have the 308's. plus it studders from a mutilated spark plug that doesnt hit all the time.

327_TPI_77_Maro

iTrader: (8)

With a manual trans you can do a burnout with a 2.8, which is probably the weakest V6 ever made. It's all about getting power to the tires abrupt enough to break static friction. Once a tire is spinning against the pavement, it takes less power to keep it going.

one wheel peel

my 305 burns em off no prob , with a shift kit she jumps sideways hiting 2nd
3.42 gears and flowmaster exhaust, oh its the l69 305

JeremyNYR

iTrader: (2)

doing burnouts/ spinning the wheels doesn't require alot of power... just lack of traction. A shitty suspension can also make you spin the wheels more. put some bald tires on there and you'll be slipping all over the place. It can be fun at times... but doesn't prove anything in way of how powerful the car is. Fast cars are looking to keep traction, not lose it.

Jproz1167

iTrader: (3)

I can honestly say after swapping to a L98 with TBI verses my original LG-4 there is no comparison at all. maybe the later larger cam 305's are different but the peanut cammed 305's will always be slow. My L-98 would leave my original 305 sitting still and theres really nothing special about it. all it has is LO-3 TBI system and a 5.7 exhaust system.Sadly though gas prices and my long commute are ending it's existance under the hood.

89RS_82Z

iTrader: (2)

traction action bars, custom panhard, custom torq arm, energy torq arm bush, would put my 305 TBI against a stock or close to stock TPI, brand new tires........like i said before to each there own, and if you are capable of building a 305 that will wax a 350 then do it, and laugh you but off as you tell people all it has is a 305, try a dyno sim program to get a ball park idea on your HP diff. between the 305 and 350 you want to build, pay attention to how much it makes a what RPM and how long it hold that number


oh and BTW you can do a burn out in a tractor with a manual trans, some of us are doing this with autos.... now if you are going to run it at the track then dump the crapy 305 or 350 and get you a 400 or something

Ive got insane wheel hop problems, I'm running 275/60's. Not stock though

stock suspension?? i used tublar steel and flat steel to make the stock torque arm tighter, and that energy bushing made a differance.....traction action bars will help alot also

iTrader: (1)

if you have trouble laying rubber it's driver error. my 92 305 tbi 5spd lays it thick w/out brakes, even my 92 2.8 s-10 could chirp 3rd w/245's all around, even my 91 sunbird 3.1 front drive could lay it down.......all about breaking traction

mrpenguin_52

hey, starterof the thread here, im thinkin one of my biggest problems is my trani, czu i'v got the 3 spd auto and its deff. starting to slip (my reverse hardly even works ne mroe) so im in the process of swapping in a t-5, manual from a 84 camaro i just bought for $250...hopefully this will help me out a bit, but another problem might b the fact the i have brand new 235/60/15 's on this car that are giving some good traction but my dad and step dad(who are both car guys) think it should still lay rubber and they've tried and can't get anything out of it either but hopefully this trani will help a bit and im deffinately gunna look into my cam, a couple fo yuo guys were talkin bout 'peanut cam' vs the bigger cam, thanks everyone lol, and keep the posts comin

Well my 305 lays a nice strip, one tire fire with 235/60/15s.

Me and my friend measured it, 1st gear lasted 200ft and 2nd spun for another 75ish. Almost from telephone pole to pole. No brake used either.

And its mostly stock, mods are as below

Transgo Shift Kit in 700r4
AC Delete
Punched out Cat
Air Intake (flipped filter cover over to let more air in, and got rid of vapor arrestor.)

And its an LG4

One wheely peelies are very easy to do because when one rear tire is spinning, the spider gears are giving you a 2.0 multiplication over when both tires are spinning. If you can bust a one wheel peel tire loose, the wheel speed will be twice that of if you were spinning posi style, so it will blow it away easy. A posi will make it much harder to spin the tires (GOOD!). I have an LG4 car that will blow away the 3.42 one legger, but that doesn't make up for the fact that it is an outright slow *** car.

Well my 305 isnt that slow at all. As it stand I think it could probably be in the 15.3-15.6 second range, I know its not fast, but its not slow either.

been 12.31@108mph on a 1.67 60' time with an n/a *daily driven* 305.

car is no longer daily driven so i'm hoping for something serious with the new trans and exhaust.

I'm guessing mid to low 13's with my little 305 and it easily lays rubber with 275/40's on the rear.

Heres a fun little video; http://video.google.com/videoplay?do...71967&q=iroc-z

blue82_z28

my old 91 with a 305 tbi could burn out so good, it had the 700r4, when you held the brake and let her loose you would have quite the smoke show, but on my 82 lg4 with my 4 speed stick, i could barely get tire smoke unless if i dumped the clutch at 5k at least.

My little 305 can spin the 295/50s from a 20 roll. Most of the time its only one tire lol but it does spin both every once in a wile.

my 305 lays rubber with a borg/warner 5 speed and a powertrax locker in the rear

My 305 with an LT1 cam, ignition, Magnaflow exhaust, manifolds, aluminum shaft, slippign like a **** auto, 3.42 gears and drag radials will chirp a bit (4 - 5ft).With the old tires we put on it, it just spun till i let off.

Oh, and ever with sticky as **** tires, if it turned a little, it would peel untill i let off the gas.

I know theres a video somewhere here. My buddy john's Stock 305. Just a cam and intake, and a nos shot. Spanking a viper. think it was a 300 shot of nos. The thing ran 11.7 on a stock 305 long block with a peanut cam.

All it needs is an energy drink and their ***** drop

mrpenguin_52

is a locker just as good as a full posi rear end or are they pretty much the same

Brisk, those are deffinately some nice burnouts, u have anything done to that 305?

i like to think that ground type affects whether or not you leave rubber. that being said mine leaves an awsome smoke show without pbing it. on 235/55/16's. even when i put brand new tires on.

Ive got an 87 IROC with a stock 305 TPI, stock 700R4, 2.73 gears with limited slip, and 245-45-16's.

All I can do is put it in 1 and squel the tires for about a second. Then it plants you in the seat and goes.
