Well sort of. We fired it up to adjust the rockers.
Is a 383 kit rated at 452 HP with these components...
-mild cam 214/220 at ??? lift
-exhaust manifolds
-stock GM old prod. intake
-750 carb
-crappy 882 heads(were offered with the kit, but i already had a set)
at 9:1 comp.

we customized the kit...
383 11:1 comp...maybe higher??
bigger cam 292 dur. 230/230/ .480/.480
headers
Torker II intake
still 750 carb
paid the extra for 041/186 300 horse double hump heads

so with these extra's I'm hoping I should make the 500 horse mark...that would be sweet.

Oh yeah, and the T5

 

My guess is more like 400HP even if those heads were ported

Daz

 

So exactly how do you take a rated tested kit, add better heads and a bigger cam, and then it makes less horsepower. You just keep reading those magazines...

 

well i also think that you have your projected HP set to high also.
but the only true way to find out what you are making is to have it dynoed. i look forward to seeing your printout and will take it you never post a print out that you fell short of your goal
good luck

 

good luck with your 500HP engine

Daz

 

Oh, I have fell short of many goals
Probably this one as well, but the original setup was built and tested as a baseline to work from. This is all from the engine shop that i bought the kit from.

 

just curious..who rated this kit??

Daz

 

With the original "kit" components, you'd be lucky to get 300hp at the flywheel. Might squeak 350 with the 2nd listing of parts.

 

Sorry to break it to ya...

 

ya I am going to go with TriggarGTA on this one.. I have heard alot of yappin but run it on the Dyno and find out for sure.. I am building a 350 and everyone is asking how much horse and I always tell them what i have in it... and they can make there own assumptions... but one thing is for sure it better be more than 221 RWHP or I'll be pi$$y hahahahaha:rockon:

Was this a business that put together this engine for you? If so did they guarantee the power levels from this motor? If they did, I'd like to see some proof. Also, if they stated these levels, its fair expect the motor to perform as they say. How much did you pay for the motor? You don't have to post it, but you should be asking yourself if you got your money worth. I'd seriously consider talking to a lawyer about this, you might be able to get some of your money back through a small claims court. If they have it in writing that first combo will make 452hp, they are committing fraud. There is no way in hell the first combo could make 452hp unless it had a 150hp Nitrous kit on it.

 

LOL.... put me down for NO WAY IN HELL as well.

 

Cruz'N Bruz'R
i do think you have a good combo with your engine... i just think that you will fall short of you goal. thats all. you will still make very good power just dont be suprised if you dont make the power you want.

 

Hate to add in on the rain but you'd be very fortunate if you could make the ci number in HP... I'm predicting based on engines I've seen in action with parts of mods like that, never in tandem but that setup would probably make anywhere from 250 to 300 HP. 500 HP is not a realistic goal for the parts listed. I imagine her not having access to much lower end torque either but she'll probably make peak torque after 3000 rpm and pull well into 6000 rpm. Just get it dynoed though to be sure and that way you'll know what you got. GM didn't start making significant design improvement changes geared toward efficiency over pure cid till the LT4 engine. So generally speaking unless serious cash is spent on matched cam/heads/intake/headers/fuel system you won't reach that holy 1:1 cid to hp ratio.

I'm also forseeing some problems with going with a hotter than mild cam. You may start losing compression on the stock heads so you may only see high 9's to mid 10's on compression.

good luck with it though and prove us all wrong

 

452 is the base number that we were given over the phone. One of the kits were 401 Hp with a different set of pistons that were a low low comp. ratio.

I myself am not sure about the 452. I'm hoping for 500 if they are totally correct on there claims. But those who don't say a 383 with a simple combination of these parts can make 300 at the flywheel, you need do some more research. Both myself and Acceldz have researched on better ways to do with this engine. I don't have the money for GREAT heads yet, but the internals are ready for whatever i want to throw on top.

I plugged my specs all into the Dyno 2000(which I don't really trust) and it pops out 429hp @ 5500rpm. That seems more realistic, but I still am hopeful about the 452.

And the pistons with a 64cc head were rated at 11.47:1 comp. which I think is too high so I'm going with the bigger cam to bring the comp. down a bit, plus I love the sound of a rowdy car.

 

Oh, and the Dyno 2000 says torque peak is at 432 @ 4500rpm. Which I thought would be higher for a stroker.

 

No offense guys but raise your hand if your engine even makes 300HP. Yeah, that's what I thought. Dave was told by a reputed engine assembly house that his engine would make 450HP. While I think those numbers are somewhat inflated (and so does Dave) it will still be a pretty strong engine and it will be even stronger down the road when a half decent set of heads are added.


Now...........

What message are you trying to convey here?

 

/me raisies right hand and raise the left 3/4 high

lol

Daz

 

WTF because i dont have a engine that make over 300 i now dont know ****?

 

Well, that's one. I've never dynoed my car so i'm not going to run my mouth.

Daz, that was kind of a rhetorical question but it's cool that you've got a healthy engine:lala:

 

The message I am conveying is simple just that....
383's are Torque monsters and it will put out some huge numbers but since I have been to a Dyno it put alot of frowns on people's face's so don't get all hyped about it.. cause it probally won't happen..

Now Desktop Dyno.... I have seen and tested and that flippin program was 3 hp out on a buddy's truck... So maybe he will be impressed.. but once again once you goto Dyno that is all you wanna here from people.." what did it dyno at" not what they tell ya... and some of guys replying to this thread have been on both sides of the fence... and how could anyone resist jumping all over a 500 horse engine.... hahahahaha It got everyone excited..

 

Yeah, because that's what I said. Where did you get that? I was just trying to say that even though his HP predictions may be high, he still has more power than a good number of the people on this board. If you took offense to that, i'm sorry but it was not my intention to offend you.

 

So what exactly did you plug into DD2000? Cause I did a rough draft of your engine, and posted the results above... theres a big diff. there.

 

ok if this thread is getting out of control.. I am loving it... hahaha
Nobody post anymore unless you can take a JOKE or Cristism back!! HARD!! hahahaha So feel free to give it to me.. because I love a good arguement.. and I will laugh the whole time this thread gets worst... SO please don't take offense from me because I am just trying to get everyone fired up... Anyone who has seen my posts in the past know I am a S**T disturber...


So let the games begin men

Chr**t even the moderator was gettin in on it!! I gotta love that
hahahahahahah:rockon:

 

Unless Dynopower(forgot the name) in Scarborough is lying..

Daz

 

Man that was a good one Daz keep it going... hahahahahaha

 

Hey guys.. I am buying those over priced SLP HEADERS for my 305
1 3/4 pri aswell..(building a 350 for fall) and I am putting them on 305 for the next dyno run... any guess what i am going to make.. I bet around 300 horse eh?? hahahahahaha

Than maybe I can put my Hand up for Acceld... hahahahaha
LOL super hard!

 

Daz, remember the little exchange we had about worthless threads on this board a few months ago? Well, if this ain't the pot calling the kettle black, I don't know what is

 

Yeah, try this...

383
low performance/pocket porting
11.2 compression ratio
valves: 1.94 1.6
750 carb
single plane manifold
small tube headers with mufflers
cam specs 230/230 .480/.480

plug it in and tell me what your program gives you...

 

Hunh? Dude, you're not making any sense. Was that an attempt at a flame?

 

I suggest a deletion of this post....Hey Cruizin...If you want to discuss this my e-mail is e_daz@hotmail.com...Not to flame but why I think it would only make that much power...

Daz
87 IROC

 

OK OK...1.94 valves on camel humps????I would think it should be at least 2.02's...

Daz

 

no, they came with either 1.94's or 2.02. I think they are 1.94's.

(I physically measured the valve before the heads went on.

92Zedder, I think it's past your bedtime, your talking weird, are you drunk?

 

I think only a few sets of camel humps came with 2.02's. I think most of the later ones came with the 1.94's. Probably won't see too much of a loss with the 1.94's, if any.

 

So no-one take offence, OK.
Ever since I've been on this site, all ya hear about is hp. and about torque too, sometimes.
I often wonder what everyone's goals are. Is it just to go fast?
Hell, that's easy. A 250 hp car with the right gears, suspension and traction will run mid 13's. So what if you need to fill it up every 300kms., the money saved on hp will easily cover it.
I always say, to each his own. Guess I'm just trying to figure it out.

 

 

that is what I am getting at.. and yes I am getting tired...

 

Or a 100hp, 400lb bike will run low 11's

 

yup..What I meant was that he should be running at least 2.02' if not 2.05's!! to make that kind of power..Ill take the iron L98 heads over the camel humps any day

Daz

 

I know I'm shooting really high here. And that 452hp will even surprise the hell out of me, but to those who said that the 383 will only make 250-300 horse...you need to get your head out of your ***, put down the car magazine and go work on a car yourself. If you think this stroker won't make over 300hp, then you've never even driven a stroker or even felt what 300hp feels like.

 

That I believe!! Crotch rockets you gotta give respect...
but I am a CBR fan not Yamaha


not flamin here just a personal prefrence...

 

Soemtimes builders stretch the truth. Dave we all know the motor is going to run good, maybe just not as good as that moron builder (IMO for our reasons known) thinks it will.

Here's the DD you requested as per your motor specs:

And guys, lay off man it's his 1st motor buildup & some guy just got him really excited. heck the guy who built my stroker swore it would run 11.80's with my combo & car.....well it doesnt.

 

Guys.. doesn't 88 Camaro kid have a stroker with vortech heads, cam, intake and all and he's around 283hp? Although without the fuel cutoff he could possibly do 330 hp but at that point some other issues may arise I think...

 

Induction should be single plane..That should be good for a few ponies..If the bottom can stand the rev....


Hey Zedder,383's doesnt have to be torque monsters..It all depends on the combo like rod length,induction,crank strength,weight of assembly etc..

Daz

 

doesn't it all depend on the combination of parts? i am very new to this engine building stuff; i am in the process of gathering information at this point.

this thread is very confusing. what exactly was the original topic? a 500 hp 383 stroker? not impossible: 383 w/vortec 1.94/1.50 iron heads, 1.6:1 roller rockers, comp cams xe282hr 230/236 w/110c, 750 carb, dual plane intake, 1 5/8 headers... at 502 ft/lbs and 463hp, can 500 hp be that far off?

i'm just gonna sit and watch this thread to see where you go now.

-jim

 

DAZ: the Torker II is considered a dual-plane when in DD. Also on the street, i consider it a dual-plane because it's a midrange puller & almost acts like a regular dual-plane in the low revs.

383 Stroker is going to be very hard to get 450HP out of with even a worked Vortec head. They really need a lot of airflow to get them to breathe in the upper rpm's and stock GM stuff wont cut it. Now work them over a bit & you may achieve your goal with a well matched combo, single plane intake & a good roller setup. Anyone who knows strokers, knows they need a good set of heads or their "just another 350" at the track.

 

Putting single plane on DD might give you a ew more ponies though...

and AAAAAAMMEN on your second pharagraph

Daz

 

Plug 9:1 882 heads in, and see what you get....

I didn't mean to get in on the bandwagon.... and I had lofty goals when I built my 355, but there is a fine line between lofty goals and being absurd.

 

I have a HP goal of 500HP as well, but my 500HP is quite different than yours... .590" lift cam, 200cc ported pro action alumimums, forged 355 rotating assy, stealth ram. Even with this, I'm thinking the numbers in my sig are a little optimistic.
