ok gear heads i asked for some info on wiring harness because i wanted a professional plug and play . It seems my choice of cam isn't the most desired but i wanted some daily driveabilty with ac if needed. bigger cam might come later but my build is mine, live and learn right. For those who need to know it has a eagle forged steel crank and i-beam rods,the heads are lt4 off a corvette and have been staged 2 ported and polished. I went with1.6 ratio roller rockers flowing through 2.02 x1.60 valves.The lt4 eldebrock was also gasket matched along with the porting.It is hooked up to a borg-warner 6-speed with stock rear end. I want to try to trash the rear end before getting something more heavy duty. Oh yea i forgot about the aluminum flywheel. new to this, so dont be an ***! so is the lt4 cam still not a good choice for what i'm trying to do ?

 

LoL Thatll keep em at bay a little bit Even though most will dog 2 things Myself I think its a good starting point Especially since we know its forged Room to GROW!!! As far as wire harness if its not broke dont fix it UNLESS you wanna spin it to 8grand later A good tuner wont have any issues tuning your combo!! PM me for a good tuners # he does mail order & if your close to Tulsa Ed Write can take care of your tune But I dont have his info. The stock computer will handle 7000rpm & bigger injectors than what youve got with your combo IF you want a cleaner install tuck the wires Seen one ole boys ride done that way & I was impressed Very clean engine bay after he hid & tucked everything Youll just have to search As my old brain is a little fuzzy & dont remember the post LoL Hope my rambling helps

 

Hotcam is way too small for a 383.

 

Didnt ya read the post He said he knows this & didnt want that to be the focus of his post LoL
OP if you dont wanna keep it stock You can go a few routes The EFI 24X is one of the most popular Theres a few others. All are gonna run you prolly around 2k or so do buy everything EFI offers a complete plug n play if your car is missing the harness in the first place!!! Its a pretty involved process

 

Is there something wrong with your harness? One thing to remember with more cubes is that a bigger cam will be more tame. I would at the very least run something like a 224/230 or 230/236 cam on a 110 or 112 lsa. If tuned right should run really smooth with the extra inches you have and provide way more power than the hotcam. What are you looking to do with the build? You want to go fast? Listen to what we have to say. As it sits right now a stock cubed cam only car would give you a beat down. You wouldn't want that would you?

 

What's your compression ratio? It should be at least 11.5 up to 12.8:1 on these reverse cooled LT motors. If you are a bit low you can just swap to 0.026" mr gaskets which will give you a good bump. There is no need to replace any wiring unless like was said you plan to spin it past 7000 rpm which is the limit of the stock PCM, or you are tired of opti failures. Then a 24x upgrade is nice. If you only want it for cosmetic reasons do a search for "tucked harness". Glad to see you went with the forged crank. Are your roller rockers self aligning or non self aligning? If you plan to spin over 6200 and daily drive it you should have a good steel non self aligning rocker like a pro mag.

 

Hotcam is way too small for a 383.

 

Wait is it a hotcam or an lt4 stock cam?

 

Yes.

Hotcam is way too small for a 383.

 

With a stroker you can go far larger and not have to worry about torque issues in the low RPM range. If you want to go with a more aggressive profile then talk to AI or GTP regarding street cams. Leave your harness alone and mill around on all the f-body boards and do your research. Tons of topics like this covered from the past years.

 

Youve created 2 threads with your 2 posts and returned to neither thread to join the discussion you asked for. Do you want advice and help or not?

 

He must be a wkend troller LoL If he would just state WHY Maybe we can help a little more Even if he only wants a baby cam for his 383 Damn thing prolly sounds stock in a 383 LoL He will want more later!!! Boost or Spray!!

 

You know the stock LT4 valves are the best part of those heads and you replaced them.......................................
The edelbrock LT1 intake has been tested and repeatedly shown to be worth nothing to a slight LOSS. Seeing as the their LT4 intake is the same basic shape and size there is no reason to expect anything different from it.

You already wasted too much money on the wrong parts, don't go wasting more on something that does not need to be replaced, save the money so you can fix what you have when you realize just how bad it is.

 

HotCam is to small for a 383,intake was a waste sell it to the first person to offer you half what it cost you . Install the lt4 intake..
Are you assuming that since you got heads off a vett that it's an lt4?
You need a plug and play harness for what?

 

Part of your problem is you never answer any questions from the people who are trying to help you. Like why do you need a new harness??????????

 

ok hot rods sorry for the delay and i appreciate all the advice. Eveybody wonders why i want a new harness. The car original had a lt1 corvette motor installed by previous owner and it looks like no care was given to the harness. Splices ,taped up areas around the injectors , o2 sensors areas burned, just in overall bad shape .I removed the motor and have not installed the 383 yet and i wanted to install a new harness because of time i could save if i had a problem once the motor was installed. I am taken the advice of several and changing the cam since stock sucks. Advice from someothers prompted this cam choice!! So here is my specs and what would be the so called best choice of cam to be able to run my ac but haul butt!! OK 383 stroker with eldelbrock lt4 intake, 58mm throttle body ,aluminum lt 4 heads 202x 160 so called stage 2 porting ,gasketmatch and polished. 32 lb injectors,flat top pistons ,pace ceramic long tube headers ,3' exhaust, aluminum fly wheel, 6- speed tranny. stock rear end, oh yea the infamous lt4 hotcam218/228@.050,525/525 lift with 1.6 rollers and guides. I still have the stock lt1 al. heads with 2.00 x 1.55 valves. So let me have it!!!!!

 

To anybody who thinks i didnt reply. Still new to this ,dont do computer talk enough to fully understand it. Have to work 12 hrs days, be a daddy 24 hrshrs,eat,drink , leaves little time for play. But dont give up THANKS!!!!

 

Have seen the 'camshaft selection guide' ? https://ls1tech.com/forums/lt1-lt4-m...ion-guide.html Lots of good info.
The guide is organized with a 350 in mind, like was mentioned the added displacement of a 383 could handle a more radical cam with better manners. How high are you willing to rev the engine? As you can see from the 'guide' even the hotcam does best at 6100-6300 and larger cams go up from there.

 

I went with a small cam and converter because of where I live and miserable driving conditions, the daily traffic and heat here in lower Texas would make driving a huge converter and cam car a pain in the ***. But you can believe when I move back to Kentucky it'll get a much bigger cam, converter and deeper gears. Maybe the OP has a similar situation.

 

I would probably buy used harness off the ebay or something. Your right to be concerned, chasing electrical gremlins really sucks.

Also, since you already have, use the Hotcam. It won't be too bad and the low-end torque will be monstrous. If you decide you want more top end, you can always change it out later.
