305 black ghost

Was wondering how many horses you guys are rolling with and with what modifications you made to get that much.

My dyno came up with 586rwhp@ 7300rpm 460rwtq@ 6400rpm, but through theory the car runs like it should dyno 800rwhp going off of the 3650lb weight and 140mph trap speed. I have a video of that actually: http://s50.photobucket.com/player.sw...fs=1&os=1&ap=1 Only real exotic parts are the big solid roller cam, the fuel injection (not really required for the power), and Procharger I was running. Anything you want to know should be at: http://www.fbody.com/timeslips/member.cgi?id=845 Been working on the turbo setup for this comming season in the idea of being able to run an 8.5 e.t.

496hp at the crank and 468 ft/lbs

I'm estimating about 1000 hp with an L98 that is stock except for the $10 throttle position resistor from ebay. "Adds 200+ hp and 60+ mpg!"

Why didn't you get two?

I don't know mine yet, I'll get her dyno'ed soon.

irockid86

you should ask the same question in the power adders section. as for me I am in the same boat as pyroviking stock l98 but my paint adds at least 400hp...just wait till I buff and add pin stripes.

I already have pinstripes but need to buff the car...how much am I gaining out of that?

dyno 400whp on motor last year, estimated 520whp on spray. mid high 10's at 127-128mph on a cold day. This year i hope to have closer to 800whp on racedays, 650-700 on street

firebird1992

253hp and 236tq on a 3.1 V6 thanks to a 150 shot that was once a long time ago when i first got the kit i think it was a little higher then that but yea nitrous+V6= the best thing on 4 wheels lol horsepower when ever u want it lol

Ca[maro]88

iTrader: (2)

180 hp to the flywheel. BUT i got hood pins so around 500rw??

5678TA

i was running anywhere from 375-400rwhp depending on weight.. through a choked exhaust, extremely old cam design (flat tappet with 260/260 duration, wayyy too large), and not the best heads.. never took it to a dyno and never weighed it.. next 383 motor should be upwards of 500-525rwhp.. or if i go LSX, i'll be looking for at least 550rwhp..

auto-x1990RS

114rwhp and 142rwtq. bone stock 3.1 V6, running through a 700R4. how my car pulled those numbers, i will never know...

spicy chicken

im going to guss 300hp
4 bolt 350
mild cam (rv2 i think)
weiand dual plane intake
holly double pumper
shorty headers with straight pipes

correct me if im wrong but i think this combo should make at least 300, it nothing crazy or anything to brag about but it sure is fast for a street car

soon to come:
bigger cam
electric fan
electric water pump
possible some aluminum heads (probibly just going to get some used iron 202's and mill/port them)

tpivette89

dont have any numbers for my 2.8L firebird, but heres the scoop on my LT4 corvette:

- hotcam
- tune
- 5 angle valve job (no other head work)
- port matched intake manifold
- muffler elims
- some free mods

car made 344rwhp on a dynojet... calculating a 15% loss thru the drivetrain puts that at roughly 405hp

J91

490HP , 501 ft.lbs at the crank. 383ci, W/JE's, Manley rods, Erson cam, comp valvetrain, RHS heads w/2.05 valves 5 angle grind, PP crosswind, Holley 750.

.... actually stepped down the cubic inches from 400+, to a 355 small block w/forged internals. Stepped up to a T-88 from a T-76. Just finished modifying the temporal LT1 intake. The 882 heads (w/8:5.1 comp) which already have a lot of work put into them are getting pulled and reworked to allow for 2.02 valves, stronger springs and additional port work. Cam is still being contemplated, MegaSquirt wiring was just laid out, and I'm waiting on the turbo headers. The rest of the car is being prepped for major abuse. Not looking to run any particular dyno numbers, as my buddy John recently ran a 10.98 over @ Atco w/just 397-RWHP in his 3800 pound, T49 powered Grand National (which was a 1.1 second difference from what the dyno said it would run). If I had to guess though, if I'm not making upwards of 800+ when all is said and done, with the boost that I'm prepping for, I'd be shocked.

MitchellDeMoor

On one of my 91's is ****ed so no horsepower there but my other '91 has a rebuilt 350 with a nice cam and I would say she is about 250 - 300 hp or maybe I am being a bit to modest. Once my buddy gets his dyno working at his shop I will get some real numbers for you guys and nt just some random bull ****.

studdmstr

I have a couple summit racing stickers on my air cleaner and a chevy sticker on the back window, so I have to be making about 1000 + hp.

89IrocZ350TPI

Full bolt on L98 so id say around 300 give or take.

pwdbychevy

Just dynoed mine today and it made 382rwhp and 425rwtq with very little timing and no nitrous. It should make over 400rwhp with some more timing.

91chevywt

I am estimating currently around 300 hp for the LT1 in my '79

Forged pistons, bored .030" and 10.8:1 compression
Crane 227 roller cam, fairly mild, popular with the b-body fellows
Freshened up heads, just rebuilt the motor.
Headers, fairly free flowing exhaust
Stock tune, stock injection for a '93 z28

Should be able to get a little more power out of it with a tune, maybe 320? Then I'll be looking at some spray, hoping to make low 12s eventually. With 4.10 gears in the rear I think its achievable. Looking for 13s n/a

It is a handful compared to my 91 TBI pickup, which makes 160-170 hp new, and its basically stock with 154k miles...

iTrader: (1)

Heck if he is getting 1000hp from a stock L98 I should be around 8000hp with all the mods I am running on mine.. He must be new to thirdgens or he would have known he would be about 240hp stock.

10secondhopeful

I don't know if you noticed or not but that post was laced with sarcasm lol as are alot of the posts on here...

hmm... 350 with a mild cam, weiand xcelerator intake manifold.... im ganna say like 250hp and 280-300TQ. lame i know, but enough to take the r!cers around here.

ibmtech

iTrader: (1)

Hard to say if when someone is really truthful or they actually don't know.. 1000hp is a very respectful number, just not on a stock 350.. LOL

Chenier

I'm not quite sure I have a 305 H.O. but with a Holley Projection TBI, Raven Exhaust, no cat( where did that thing go?), Bosh Platinum/IR Fusion plugs, ACCEL racing plug wires. stock is 190hp but I'm not stock, I'm guessing 210-230 depending on conditions. I do have allot more planed for the motor. New headers definitely, because the smog pump stuff was gutted. New intake manifold eventually, I have the ability to port and polish so ill prolly port match the TBI to intake and then intake to heads. I got all summer to plan and work on it. Maybe Twin Turbo, or 500 shot of nitrus? Auxilary Turbines?

roughskinjrz

i have 489 stroker with 871 blower on top. dyno'd at 815 horsepower with 1 7/8" headers, i am running 2.0" ceramic coated so it should be 850 but ill dyno it again once its in the car. i have a th400 full manual reverse valve body with transbrake, and a 9" ford with 3.70 gears and spool in the rear. running weld pro stars for wheels.

fryer1979

My third gen is an easy guess, 0hp/0tq. No motor or trans, but am hoping to be able to transplant a LS1/T-56 combo ranging around 500 hp/tq. My second gen I'm going to guess in the neighborhood of 300 to 350 hp/tq, unfortunately there is no dyno around here for me to know for sure.

UnderCover89TBI

about 235 hp to the wheels

d00012

135-140 Hp...and that's not at the wheels...

v10viper04

When all is said and done i hope to be 375+ at the crank. My goal is AT LEAST 300 to the wheels.

paul_huryk

I never dynoed my Camaro, but based on what the 1/4 mile speed is it is running between 398 and 401hp at the motor. On the nitrous (also based on the 1/4 mph) it is making about 545hp (on a 150 shot). This is at 3525lbs in full street trim.

I can only guess that it makes about 330 to 340hp at the wheels on the motor.

457 horse @ 6100 rpm!! Fun times...signature has some of my mods in it...

chaoz28

how in GODS NAME??? im pullin 385 whp with 432wtq and i get 8 mpg if i drive like a human being tell me your secrets hahah

Burgundy Bomber

550hp 1200 torque.
no really.... but that's in my tow rig with some ridiculous mods and money.
"black Camaro" has a 235hp mild cam 350 in the garage sitting on ice.
"Red Z-28, prolly 325+ to rear, have big plans to make up for that with deap deap gears soon, I'm thinking 5.56

bmfIROC-Z

iTrader: (1)

havent dynoed mine yet,but im guessing i should be somewhere around 330-340rwhp.

ThePain

My 92 is just a stock RS, so I only get ~245 hp

10secondhopeful

Stock a l03 305 tbi pushed maybe 170-180HP. If it really is stock then thats what it has, or the v6. Why do you think you have a 350 stock?

v10viper04

170 stock, around 150 to the wheels. and with miles on the motor probably like 140 to the wheels.

10secondhopeful

He probably mistaked it for the l98

v10viper04

Probably....

pwdbychevy

The L03 that I had in my car previously made 200hp at the wheels with a Turbo City TBI, S/R Torquer 305 heads, Edelbrock TBI intake and a Crane Cam with 1.6 roller rockers. It was ok but not good enough. Then came the 383....

ThePain

It was supposedly special ordered from the dealer with the 350 engine. See for yourself.

fly89gta

iTrader: (1)

That's a L03 man...

That sure as hell is no L98

See the difference? Just pay no attention to the giant hair dryer attached to the motor.

ThePain

****... Well I'm glad I came here now. I always wondered if It was that good (The speedometer only goes to 110...) But my dad was like, Yeah! 240 hp easy!


I feel kinda embarrassed now.. I wish I'd have asked someone before saying something like that.

studdmstr

Just an FYI a 350 and a 305 look identical on the outside so that pic does us no good. I'm pretty sure that you couldn't get a L05 engine in a camaro from the factory. About the only way they could have bought it off the lot with a 350, is for the dealer to swap out the 305 before selling it.

383roller

350rwhp/380tq-on dyno jet
383w/ 10.5:1 compression, ported stock 350 heads, hot cam, overpriced miniram
just rebuilt it w/more compression, bigger cam, air gap and 750 carb
waiting to get it back with better results-all i need is better heads im shooting for atleast 420rwhp w/aluminum heads

pwdbychevy

Are you using 5.7" rods?

383roller

yes

406z

406
Stock double triangle sbc heads with comp valve springs
Cam 480 lift
crank and rods are stock.
Edelbrock Perfromer rpm with edelbrock 650 performer carb
It pulls stock c5 z06's. So it does alright for a budget build. Lets say 290whp
If i keep it...I will eventually run a little wilder set up. Afr 210's, forged crank and rods, cam around 560's lift.
