95 lt1 383 stroker project questions I have a 95 Z28 6speed, 4.10 gear, cold air kit, under drive pulleys, long tube headers and some other minor bolt-ons. I am about to start my 383 project but I am trying to get away with some stock parts until I can afford to replace them. It will be a forged built 383, ported heads with a 232/240 cam and the clutch will be replaced when the engine is done. My goal is to not have to pull the motor again as I add the parts.
The questions I have are...
1. Can I get away with the stock intake manifold, fuel injectors and ignition system?
I know the rearend will need upgraded but I dont hook up well enough or run it that hard to worry about any of that yet. Please add anything else I may have overlooked, thanks

you can usually find a ported intake manifold on here for pretty cheap.. ignition system is fine. you will prob be fine with some 30lb red tops and a walbro 255 pump for your fuel system

If fuel injectors are the only thing I have to change that makes me feel better about getting this project started. Replacing the intake plus porting, throttlebody and ignition could set this back a few months. Thanks for the info and like I said before... if anything was overlooked please let me know.

I would not go running some random ported manifold because different porters remove material from different areas creating a potential missmatch. Besides the untouched stocker is good for more than most guys manage to make NA anyhow.
The real concern I see is that you are going into a stroker build with the idea the intake needs to be addressed as does the ignition which everyone is agreeing you are way off base on. Then the injector thing.............................
I would argue the best thing you can do is STOP because if any other part of this build has been planned with your current level of cluelessness I see a whole lot of fail in your future.
Have you thought about a fuel pump?
Have you thought about the axle?

I agree with the other statements.

If these where your only questions you need to do alot more research before you start touching your motor.. not being mean/putting you down, just being realistic

IMO it would be a whole lot meaner to say you have it all figured out and let you fail without trying to help. I have hurt a lot of feelings over the years with posts like my first one in this thread, and a number of guys who's feelings I hurt later came back and sent a PM saying "I should have listened".
On fuel injectors and pump the one critical thing people forget is we are not talking about what stock stuff can feed but rather what 17yo stock stuff can feed, that is the biggest reason for needing upgrades. I know Ed Wright has posted about using the stock fuelpump FAR in excess of what pretty much anyone else would even consider, But we can't assume a 17yo stock fuel pump or injectors are in perfect working order anymore.

I would have to contact the guy who will be building the motor to find out exactly which crank will be put in. He said the cast Eagle 3.75 could be used with the factory flywheel but I want it forged and the flywheel doesnt cost much to replace.

There are two options.
Stock or Forged. No aftermarket cast cranks.

You do make a good point. I have owned this car for 15 years and its easy to forget its not just what a stock part can handle... its what a 17yo stock part can handle. The fuel pump has been replaced and I wish I knew what kind of pump was put in it.

Do the bottom end as strong as you can so it will take whatever punishment you might throw at it later on. The only problem I see is that you haven't decided on heads yet. That will effect your piston choice based on chamber volume. Are you running n/a? If so You will want static compression to be around 11.5/12-1. Check out the chamber volumes of some ported heads. Some keep it the same while others remove a little material. Also, if your block ends up getting decked a significant amount the pistons may be flush with the deck. Running different thickness head gaskets can get you ideally where you want, but it's better to know the entire package that you want to run right now before you purchase anything. I think the cam you have picked out is going to be too mild for a 383. You'll be leaving a lot of power on the table with a cam like that.

Glad you said something. I was thinking about going with cast crank to save some cash but I am quickly learning I should save my money and do it right. I might have to put this off for a few more months, maybe another year or else I am asking to fail like 96capricemgr mentioned.

Far as the cast crank thing that is a huge red flag that he would consider using a cast eagle crank.
put the project on hold for quite some time and find a competent shop while you do a LOT of reading.
Lots of us have made a lot of mistakes already no need for you to repeat them, just look around and figure out who you want to trust and then ask questions.

Racetronix has already stated it will be at leas summer before they have wiring for the 340 pump sorted out. Why suggest wildly overkill parts that wont easily fit?
