at least u all now know what my motor does i i was not full of ****.

well 450 and 500 where a little high wishful thinking .sorry

laiky

has anyone noticed that those numbers seem to be from a chassis dyno?? 430 rear wheel HP? Thats over 500 at the crank!

that familiar smell again.

ljnowell

Of course it is BS. Just like all of the crap in his signature. Double pumper edelbrocks, close chamber 882's, and of course 11:1 flattops (pretty good w/76cc heads).

kind of made that guy up so u guys would beleve me.

i would like to end the war to thats y i had it dymoed but i still get **** what will it take???

ljnowell

No one is ever gonna believe you because of the lies you have. I like you new signature. Good thing you got rid of the made up stuff. Well, except for the close chamber 882's.

1981z28

CUSTOM CUSTOM DO U NOT GET THAT THATS ALSO THE REASON THEY CAN MAKE 400+ I HAD THEM DONE AT MIKES SPEED SHOP $750 OF WORK DOWN TO THEM THATS Y THEY ARE SO GOOD

1981z28

thats what i have and thats what it makes if u dont beleve it say so and move on.

ljnowell

Im saying it loud and clear, but I dont need to move on. It doesnt make that crap, and you know it. what happened to the double pumper edelbrock, did you sell it for some 13:1 dished pistons?

1981z28

O YEA

1981z28

IM SORRY NOT CLOSE CHAMBER HEADS CLOSED CHAMBER NO DAM WONDER U WHERE GIVEING **** MY BAD DUDE.

WE ENDED THE WAR PEACE ITS OVER I GIVE UP CAN WE JUST END IT.:hail:

1981z28

9.2.1s flat tops . the heads are 882 close chamber heads highly modded . and it is my dyno sheet but i hade help building the motor it was my friend who was teacher\pal who helps me about cars ok. i didnt want to look like a full thanks u made that impossible im still learning i did not build the 430hp motor my friend steve did. i know alot but not everything . i hope we can start on a new foot know .


the factory version of my power pack heads
Large triangle over rectangle (“crown”) 882 Large chamber (76cc), hardened exhaust valve seats, compromised intake port(‘71-’76 350/400cid), best of lightweight heads

84firebird383

Damn I wasted alot of money on my brodix heads. I should have just used some 882s

laiky

get rid of the flow-masters cats, the alluminum rods and the pro flow breather thing you made up and then i'll think about it.

supposing you are telling the truth now, the damage has been done. I don't spend tim eon this board asking and answering questions so some trash talking schmuck can BS me. For the most part you either keep it to your self if you want it to be a secret, or lay it out on the table so others can learn from your experience and help with your problems. This board is for SHARING information.

1981z28

the rods came with the kit if u want a link to the website i got it off of i can give it to u. and the pro-flow breather is the filters that come with any edelbrock breather.there all called pro-flow

http://www.speedomotive.com/383%20Mighty%20Mouse.htm


this is the kit i got with some add ons. there is a better kit this ones base is only $549.00

laiky

alluminum rods don't seem to be an option. Besides, you do know that they will quickly streach in a street motor and eventually let the pistons contact the heads.

1981z28

4340 FORGED H-BEAM RODS ADD $240.00
its right at the bottem and i drive my 82 daily this is just a race car.

1981z28

yea i used the factory motor no i used the motor out of my 1970 c10 look it up 300hp and 380ft.lbs the 1981 was only rated at 175hp and 300ft.lbs

SOLID LIFTER

It's amazing how many lies one person can spew. I'm up to my neck in here.

As hard as 456 hp at the crank was to believe, 431 hp at the rear wheels is impossible to beleive.

Just stop lying!

laiky

4340 is a chromoly alloy, it is also steel not alluminum. Now i do not believe you have even seen these rods you keep refferring to. the difference between steel and alluminum is pretty drastic. it is unlikely that you would be able to fit alluminum rods into a stock block as a stroker, did you have to clearance the reluctor shaft? what about the lifer valley brace? please tell us what was involved in getting the rods to clear.

ljnowell

Yep, I said it earlier, and its true, He read a bunch of parts catalogs and magazines and put it all in his sig. What a weenie

84firebird383

:werd:

ljnowell

Actually, you probably did. 1971 was the year chevy went to rating engines with the accessories installed. Prior to that they were rated bare, just the engine.

screaminformula

well, right back at ya bud. you didn't say you used a 70 motor. you said your factory motor, which would be a 1981 350. or 305...or maybe even a 267. i'm gonna stop now, you are burying yourself so deep already that if everyone here threw ya a shovel (pretty much everyone already has) you would STILL not be able to dig yourself out. i think you have convinced yourself of your own lies...i refuse to get in a battle of wits with an unarmed man...

Josh

screaminformula

well, i wanna see where ya got your proof from, because i have a pretty decent amount of computer skillz, and you say you have none, and i cant find ANY specs for these motors...so help me out if you are so sure of yourself...go find it and post a link...ill keep lookin...

Josh

ljnowell

specs for what, the 1970 engine that the poser claims he has? The link for that stuff is
http://www.edmunds.com/reviews/gener...9/article.html

However, when you change pistons, rods, crank, heads, cam, intake, it doesnt matter whether it came out of a boat or a car, its a 350 block. But you cant tell people like him that. They are the ones that start threads like "got my new vette motor" and crap like that.

screaminformula

i know it doesnt matter in the end, but i am just uncovering one more lie...the factory "specs" he spouts off...and that link DOESNT show HP and TQ ratings...i think i might have busted this lie already...ya cant FIND THE SPECS

Josh

ljnowell

the factory HP specs are listed, but not the TQ.

trans_am_ta_84

well i'd just like to say one thing.. my friend's uncle built a 383 stroker and put it in a 58 morris minor and it was pushing almost 550hp at the wheel. he owned his own shop and didmotors and trannys so i know he knows what he is doing so whoever said you can't get over 500 with a 383.. well i've seen it. and no he didn't have a blower or nitrous. actually he had a blower but he didn't put it on he said he wanted a fast n/a car.. and thats what he built.

25thmustang

Wow lost respect for a member on here!

ljnowell

No one said you cant get that kind of HP out of a 383. Not once, ever. I dotn know where the hell you got that from. This guy is spewing all over the board, making up parts that dont exist to listing parts that are incompatible and wont work. Its ridiculous to say you cant get that kind of HP. My brother, thegeneral, had a 350 that was pushing 500. It isnt that hard, just expensive. No one is saying it cant be done, we are all just saying that this guy isnt doing it. If you cant read these posts and realize that, then you should hang out with him.

ljnowell

BTW, next time read the post before assuming someone else's ignorance. All it does is prove your own.

trans_am_ta_84

actually look in the begining and you will see that somebody said you can't get 500 out of an n/a 383. don't get smart with me because i know what i'm talking about go look it's in begining somewhere. good day

ljnowell

yeah, dont get smart with you, you know what you're talking about right? Cause your uncles brothers cousin told you? Troll.

ljnowell

BTW, genius, show me where it was said that you cant get 500hp NA from a 383. Just quote it here so we can see it. I have read the whole thing over, and no one said that. We said he wont get it out of the combo he is planning. The only statements about turbo or SC was along the lines of:

did I miss a turbo or something? No way that combo makes that!

no where does anyone say anything about a 383 not making it. Crawl back under the rock from which you came with your "heavily modded tbi"

rx7speed

first off the dyno sheet can't be correct
hp is based off of torque
the formula for finding hp off of torque is
hp = (torque x rpm)/5252
so the forumla for finding torque off of horsepower is this
torque = (hp x 5252)/rpm

so your original numbers had to of been incorrect
as was stated by someone else it would put your torque based upon the hp way above what you claimed the peak torque was

but then again I noticed the edit
from this Originally posted by 1981z28
no its not

"dyno 456hp@3500rpms 494ft.lbs2900 rpms
these are the dyno numbers 450 500 just sounds better. "

sounds fishy when you have to update right when someone proves your numbers wrong at least with the rpms you had listed


now as far as a mistype?

the keyboard is not setup to where 52 and 35 can be typoed
even more so going from 29 to a 42 to type those woudl be hard to do

so that right there is flag number one


now you say 882's are good heads

http://www.chevytalk.com/tech/engine/SBC_Heads.html
that link right there says this about them

"882" – 333882. These heads were found on early-late 70's 350 and 400 engines. They had 76CC combustion chambers, 1.94/13.50" valves, DO have accessory holes, intake port volume is 160CC's, exhaust port volume is 60CC's. These heads are made of thinner castings and are prone to cracking as well. The exhaust port on these heads is rather weak in my humble opinion, and is not considered to be a good performance head. I have read some flow numbers on the internet regarding the 882's, and I have a hard time believing some of the flow numbers people are posting on these particular castings. I did extensive flow testing on several of these particular castings, and was not very impressed with their flow characteristics. The 441 or 487 are a much better large chamber head (in my humble opinion). The 882 intake port is very close to that of the 624, the exhaust side is where the 882 is weaker.


basicly they come with HUGe combustion chambers making it hard to get high compression out of them (there goes your 11:1 unless you are running big domed pistons

they claim the casting is thinner and weaker which means not much room for porting
their intake volume and exhuast volume isn't that much which prolly limits flow
and the time they came out?
early late 70's?
those really are not the per formance days.those are the smog hurts everything days


third thing

you went and had your car dynoed at a friends dyno and came up with
went and dynoed my car at my freinds shop.
456hp@4200rpms and 431ft.lbs@5200rpms
first off your torque dropped down almost what? 60lbs/ft?

second your nubmers can't be right
456hp@4200 puts you at 570lbs/ft of torque at 4200rpms which beats your claimed 431lbs/ft

please if you wanna make something up make it a little easier to believe

there is an attach file when you try to post a msg

rx7speed

as I see the picture of this dyno the 456hp
that woudl be what? about half way between 400 and 500?
for the hp line it doesn't even go half way
as far as the torque curve i tis listed as 431 but yet it goes well above 1/4 way between 400 and 500 making it seem more like 475 or so

I would say someoen photoshopped this dynograph

ljnowell

Wouldnt surprise me. Look at all of the above changes he made. Changed his signature, changed his posts everything at least 3x. There is another one too, if you follow both threads where he is talking ****. He claims to have paid 750 for the headwork, but at the beginning claims that he spent 1200.

25thmustang

I caught the $1200-$750 change as well, but I dont think there is much doubt left here!

ljnowell

And the list goes on and on. I guess the other boy genius decided he didnt want to post a reply. Good, because he is about as goofy as this guy.

ljnowell

All the time, you see it all the time here. There are some guys in another thread arguing that TPI is the best thing ever. At least they arent pulling this crap out though. They are misinformed, not liars.

rx7speed

TPI by FAR is not the greatest thing ever.
now tuning the intake charge is a very good idea but the design that GM used more or less SUCKED!!!!!!

great for the time by compared to what they are doing with intakes now the small restrictive intake runners tuned to such a low rpm range when mated to a good healthy 350 are going to show a nice drop in power VERY quickly
great low end maybe but nothing else really

ljnowell

Exactly the truth. Some people would swear it is the best thing for performa
nce.
