any power adder sbc should be able to crack 9s. Nitrous, nitrous and nitrous.

it can be done with a big inch solid roller sbc and nitrous pill. 87 TA went 10.07-10.09 with a 406 and 150 shot but didnt spray untill abit into 1st gear. on the launch it might have went 9's. 200 shot would have cracked

else run some boost on one, and it will go 9s. 600-700whp is fairly easy in a boosted motor. in a lighter car, that will crack 9's

My car 3400lbs went 9.70 at 140mph on a 275hp nos kit.

I've been 6.62 all motor with my 406 in the 1/8th, should be around a 10.20-10.30ish in the 1/4. So 9's is very possible if I stepped my motor up. It's just 12:1 with a .618 .622" cam. 3230lbs.

iTrader: (5)

my old motor was pump gas in the 9s. lots of nitrous on 110 though, albeit a 355 engine though, nothing to radical, just had a fuel cell for nitrous that I put 110 in to be safe.

ross

My 380 ci motor ran pump gas on motor I have a fuel cell for the nitrois side with 110 oct on the nitous side new 434ci motor will run pump gas all the way.

camaroal9668

me and my brother hit 10.38@127 with a 383 last year ,this year with a 415 sb n/a looking for 9.0 - 9 teens ,i'll post a time when we get out there

z28freak84

how about sharing engine combo info for both motors. Cam, heads, CR, intake, carb, plus trans, converter, reargear, etc.
nitrous??? how big a hit???

sixpackmtrspts

im hoping to hit 9's easily wth my combo, 8's would be better.
82 camaro
362in small block (big bore small stroke)
18* bowtie heads flowing 380 cfm
hogans sheetmetel intake dual hp holleys
16:1 compression
alum rods
really big cam
anticipating 900hp or better engine is still being put together. last combo these heads were on was a 330in sb and it dyno'd 846hp @ 8800rpm

car is getting caged to sfi spec to run quicker than 8.50's
lamb brakes and struts, for now a powerglide, coan converter about 6500 stall, might switch to a 3 spd proflight later on.

car will be nhra super stock modified legal. car should be done in late april.

camaroal9668

it was an ALL MOTOR 383 2 bolt main, eagle rotating assembly,aluminum heads,750hp aed carb,1.82 powerglide w 3800 stall,12 bolt moser with 4.56,3200 lbs my brother knows all the #'s like cam profile and everything else,it was a budget motor nothing crazy, it is now getting freshened and put in a vega
----------
it was not a shelf cam, my brother knows a guy at isky named rod he helped with the specs,hope that helps

z28freak84

SWEET!....ALL MOTOR. If you get a chance, find out what HEADS, and CAM specs, and Compression. Oh, and intake too. Thanx. Later.

strokeronthesause

i guess the pump gas part didnt make my combo appealing to anyone.LMAO
23 degree head too. i have not seen this duplicated as of last year. sure there is faster cars but i can drive my car on the street all day fill it up at WAWA and goto the track and race. my car has been 1.36 60ft with 26inch QTP on motor!!!! STOCK SUSPENSION AND A STOCK 350 BLOCK....ANYONE? looking for something to compare to!!!!

daverr

iTrader: (1)

very nice setup u have there. I guess u dont get the recognition because it`s not a LSx motor. And there`s no such thing as a streetable SBC doin 10`s 9`s on pump gas because it takes a LSx to do that.......NOT .

strokeronthesause

lsx based motors are a very good design and very efficient.....but they still dont beat sbc/carb combos!!!!

Smokin87TA

iTrader: (2)

I do agree the sound or a old sbc is just mean. I have had 2 built 355 sbc's and i have to say they really dont compare to lsx engine's. It is 30 years of technology and 15 degree heads so its kind of apples to oranges.

What about lsx based combo's with a carb? I have a cam only ls1 in my 87' and i will be running mid to high 10's with the stock heads, stock shortblock, stock intake manifold, stock ignition, ect. 346ci only a off the shelf cam. Plus a 200 shot should definitly get some low 9's. Plus i get 16mpg with the 5500 stall and 4.11's around town.

My next motor will probably a 408ci iron block lsx with l92 heads(flow over.330 stock, and under 1,000 complete assembled. Cam around .650 lift and about 12:1 all on 93 octane. Should be good for some mid 9's on motor plus a 200 shot on that.

looks like a good combo............i got one for ya....same cubes and compression in a sbc with less gear 9ohs on motor and on spray...OMG!!!!

Smokin87TA

iTrader: (2)

Yea with aftermarket heads...... Im talking about going mid 9's on bone stock gm heads. Sure thorw on some aftermarted heads and your well into the 8's. and dont tell me that the 408 sbc is running 9.0's on stock heads. Im not trying to make this a sbc vs lsx pissing match. your car is very badass, i just watched the vid of it.

ross

Stroker I used the afr 195 heads on my 380ci motor that went 9.70s on spray not a bad head for the money. My car weighed in at 3400 lbs with me in it 3500 stall turbo 400 3.89 gear 28 in tire only had 10 to 1 comp soild roller and vic jr with a carb shop 925 cfm carb and hooker log tubes with 3 in no flow mufflers
----------
Smoking 87 are youre heads ported? I have worked on a transplant car and with ported heads cam and some small bolt ons it went 11.50s on motor but the d--m rear end kept going south in that car.

Smokin87TA

iTrader: (2)

No, they are bone stock 853 castings, no milling or anything. They are the not even the desireable 241 castings from 00-02.

ross

Wow that is impressive to run in the 10s with just a cam swap and bolt ons . What track do you run at?

Smokin87TA

iTrader: (2)

byron il and sometimes union grove wisconsin. There are cam only stock ls1's going 10.2's and there are even guys running 10.90's on completely stock motor's no cam or nothing. Plus thirdgens are a little lighter than 4th gens anyway so better for me

strokeronthesause

your comparing apples to oranges 23deg to 15deg head.......408sbc will go 9.0 or faster with a stock head its called a 106mm.LMAO

DIGGLER

iTrader: (1)

unsure of 1/4 times as of yet, but so far mines gone a 6.61 in the 1/8 with a 100 shot. im looking to run some 9.70's once i get it dialed in a little better and start upping the shot.

this is with a stock LT1 with a 230/236 cam, mildly touched up stock heads. car is ~3100lbs. its still fuel injected, and it got 25mpg when running the 6 speed. (now has a th400)
with a race oriented cam and a good set of ported heads it would be dang near 9's on motor.

rik89gta

I'm running a 9.060 at 77.11 mph. In the 1/8th mile of course.

my old 87 was running 9.97 with 383 with phase 6 bowtie heads and a 150 shot.

car_fixer

350 cube afr heads 150 shot 9.99 at 132.9 on the revlimiter from 1000 ft (7500) and thats with a hydrolic roller cam gm crank and rods, oh and by the way the oil pump pickup was in the bottom of the pan ( discoverd when changing the stock pan out for a 7 quart pan, going back to the track soon to see what it will do at a real track but at atlanta motor speedway they do friday night drags on pit road ( 1/8 th mile ) and i hit 120 at the finish line if they mesured right thats sub 6 sec. eighth = low 9s

squeeezer

now lets talk just suspension/chasis!!!!

84firebird383

A friend of mine runs consistant 9.90's with an N/A 400 sbc with a 4 speed in an 85 camaro.
