I have a 350 carb with a edelbrock performer air gap intake and edelbrock performer 600 carb. I am getting ready to rebuild it with a 383 stroker kit with 9.5 comp and a comp cams Xe268 cam. What I want to know is how much more horsepower will I have. All guessestimates are fine. Just like to know

 

give me your whole engine combination and i will run it on my dyno program.

 

ok the heads are the stock ones but the headers are hooker comp shorties. Umm comp cams magnum roller tip rockers 1.5 ratio. Ditributor is stock and so is everything else. and I think the compression is around 8.5:1

 

im guessing 330 hp? get new heads, youll see a huge diff. seriously.

whoa wtf happened....i didnt do that, that is STRANGE< sorry about that though, even if i didnt do it...i only clicked post once lol

 

my goal is around 370hp with as much torque as I can get. Then what if I added a set of world sportsman 2 heads.

 

if you run a large cam, the right manifold, header exhaust and those heads, expect 400 hp

 

Don't mind Slowmaro, he's just posting garbage to raise his post count. I wouldn't expect 400 horsepower from stock heads.

The stroker and cam should give you 30 horsepower, but you'd probably gain that by spending less by getting some better heads, and gain a lot more with all of it.

 

get soem vortec heads off a junk yard truck, and have them ported and shaved, and those will surpass 400HP

 

are you retarded??? i never said use stock heads you moron, he said "how much should i expect if i use sportsman 2 heads"

400 hp.

now go put on your saftey helmet and play with the rest of the special kids. LEARN...TO ...READ

 

Id go with a set of Protopline ironlighting heads over the Sportman II's.
A lot more flow and a better chamber.
Either the 180 or 200cc port heads would do nicely.
I'd lean towards a 72cc chamber head for a street pump gas
383 with flat tops.
SportsmanII's are well made but dated. the flow is modest
without porting compared to the Iron lightnings.
the newer protopline heads are just better bang for the buck
out of the box.

If the $$budget$$ is an issue, spend the money on new heads
FIRST
before you spend money on strokin' it.
a 355 with great heads will blow the doors off a 383 with stock heads hand down. And for less.

 

i second that, the money a 383 crank costs alone is about half the price of a good set of heads.

 

alrighty I found a set of those pro lightning heads for $735.and I decided to jump up to the Xe274 cam instead.

 

She'll be a go'er!! need some gear and a bit o' a stall for the XE274... A 750+cfm carb would be better. So would long tube headers.

Around 420 to 440Gross HP tons 'o torque.....

 

you might wanna think about getting a 2700 stall torque converter. might even think about a double pumper. and a GOOD intake manifold

 

Sorry Slowmaro, I guess I was just tired. MCATs do that to you. Anyway, the majority of your posts are garbage. You're one reason post count should be invisible.

Funny you tell me to read. I'd like to direct you here: https://www.thirdgen.org/techbb2/sho...hreadid=184134

 

What intake manifold should i use then.

 

wtf? what does my post count have to do with your inept perception lacking the ability to pay attention

 

as far as your manifold goes and heads at that, it depends on where you want your power range to be, ...upper lower or mid rpms.

just remember to kinda try to match everything up with each other, like dont get a high rpm manifold with heads that have narrow intakes made for low rpms.

im assuming you are going to get all the parts in one go right?

 

all in one go is what I am going to do. I am going to use the 200cc lightning heads with a comp cams Xe274 cam but what would be a good intake to match with these

 

performer rpm maybe? not sure....i dont know the specs on those heads honestly, nor the specs of that cam

 

the cam is 1800-6000 and I don't know about the heads either.

 

I need to rebuild my engine now" long story" I can get a 383 crank for $150 new but can I just switch it in when I go to rebuild it or do I need to get new pistons and rods. WIht that killing my budget I will prolly just get a set of those vortecs with a xe268 cam. But my main concern now is that I am going to have to tear into the engine and I can get a crank for a pretty good price I think I might as well put the crank in while the engine is apart.

 

anyone?

 

im pretty sure you need connecting rods as well. im not an expert on 383's by far. i just know the basics on them. vortech heads are *** though, id love to have a set.

i know stroking the engine is more than just slappin in a different crank. i *think* it has to be bored .30 over as well. not sure though. you are also going to want to get new bearings. also cinsider getting the crank and pistons balanced. this isnt an eas nor cheap job. if you lack the money and experiance to do it right, i sugesta 350 short block and just build the top half of the engine.

 

http://www.sporttruck.com/howto/40619/index.html

everything you ned to know just found this

 

I found something to. A unbored 350 block with a 400 crank is a 377 but if you bore it .030 it becomes a 383. My engine has 5.7" rods and most stroker kits include 5.7" rods. So techinally I should be able to put that crank in right? It would only be a 377 until I can afford to put some aftermarket forged pistons in and then I will have the block bored .030 and it will make it a 383 then Right? I know i would need it balanced.

 

thatll work i suppose., but i thought when you stroked an engine, it got a bigger crank and the connecting rods had to be shorter...i dunno...im prolly wrong...but it seems as though either the piston or the rods would have to be shorter to compensate for the longer stroke.

 

You need shorter pistons. Also, why would you tear apart the engine put a 400 crank in it (which needs to have the block clearenced) put it back together, wait 2 weeks to earn another $400 pull it all apart again, have it bored out, buy new pistons again, and put it all together again.

 

The engine is in desperate need of a rebuild thats why I am going to tear it down in the first place.Lets see I am 17 I work for minimum wage I have enough to get the crank, rebuild kit,and have the block clearanced and my step dad can rebuild it for nothing at all. MY dad is best friends with the boss of a performance shop so if I need the block clearanced I can get it done cheap. As for getting new forged pistons It wouldn't be 2 weeks it would take alot longer that. With what I make .

 

Ok, I understand your money problems, really i do. But in most cases a bored cylinder is almost a necessity. What happened to the engine that it needs a rebuild?

 

why do you need forged pistons? i mean..liek i said, im nto a 383 buff, but i doubt you need forged internals...i somehow dont see you making over 400 hp in the long run. like you said, you are 17, you cant really affoard to super charge it...only run forged if you plan on shooting nos, which you shouldnt in the first place ....no offense but i dont suggest a 17 year old thats been driving for 3 years tops to start shooting nos lol.

if money is the serious issue, just get a short block 350 and built the top end of the motor up, and you will be happy with 350 hp and will be 800 dollars less broke.

but if you really want the 383...you must have it all done at the same time, pistons, crank, clearance issues adressed, balanced, bored. its alot of work and money...i say 350 man....seriously...

 

hey thanks guys. I think I will find a short block 350 and go from there.

 

You will like that combo. Make sure you got the exhaust figured out and a decent carb.

 

You replyed 16 times in this one thread.

 

...and....no one else was helpin the guy, figured i would ....didnt know i could only post a certain number of times in one topic.

the sad part is, you actually counted how many times i replied. lmao :sillylol: :sillylol: :sillylol:

 

yeah and thanks for the help Slowmaro

 

not a problem....

 

Wasn't too hard to count, outside of South Carolina we can count past 10 without removing our shoes.

 

lol did you really just try to insult me due to my origin? thats funny. you are eing arrogant. please refrain from posting your stupidity.

 

If only you followed your own rules ...

Gotta love someone who can't fix their own car trying to give advice, and who can't spell or use capital letters but calls other people stupid.

 

kevin, stfu. you are a problem on this board. all you do is insult other people and think you are better than everyone....either post helpful info, be nice, or take your aggression out on an inanimate object. dont bring it here. may you suffer from herpies, and have rectal problems. begone.

 

I usually wish a guy an "eternal soft-on".

 

SlowMaro is now on my ignore list

 

wooho, im on someones ignore list and i didnt even say crap about them, ...all hail...king of the over emotional! rofl.

 

Not sure where you got aggression from, this is strictly amusement. The more garbage you post, and the more offended you get when someone calls you on it, the funnier it is...

I've posted a whole lot more accurate, useful info here than you ever will. Have someone show you how to use the search button.

And it's spelled herpes, go re-read your prescription bottle.

 

Slowmaro helped with the problem so just lay off him alright. Learn to be nice and give compliments they really help your self esteem.
