This thread will be about my Iroc I purchased a couple months ago. This is a complete build from inside to out. Remember this build is while being on a college budget. So lets get started!!

 

Here's some pictures of the car when i went to look at it the day before i bought it. Got it for $1000 with an 87 350 out of another iroc.






There's the motor in the back of my truck with my girlfriend behind it

 

My first love towing home my new baby

and now shes in the garage

 

Ended up have to drive my truck into a ditch in front of my house, removed the tailgate, hooked it up to the stand and after a lot of effort got it into the garage.

Sold the heads and intake manifold for $150

That is because i got these nice old 062 vortec heads for $200

 

First thing first I moved into my girlfriends house and got the garage set up real nice. Started of with a racedeck flooring.

 

Pulled the whole interior first. got the carpet and seats steamed cleaned. I dont have after pictures yet but i have before.

 

Yesterday i prepped the interior pieces and today i painted them. Here are some pictures of the process. I used the satin colored crylon plastic paint.

 

Tomorrow i will gloss them and paint the carpet with duplicolor.

 

subscribed, body looks straight and clean paint doesn't look bad at all either nice find!

 

Thanks man i appreciate it, looking forward to some good advice from the thirdgen community while i build this!!

 

Youve hit the bullseye on third Gen knowledge this forum is an abundance of information and welcome to tgoman

 

Its funny bc i always stumbled upon this site when i was using fullsizechevy.com for my truck haha. Thanks for the welcome to the site!!

 

what are the plans for the iroc

 

350 Engine:
bore it out 30 over
vortec heads
edelbrock vortec intake manifold
keep the tpi injection
no clue for cam or anything else really

Transmission
t56 swap

Interior
keep all original except add new speakers, head unit, and amp

Steering, suspension, brakes
just go over everything

Any suggestions?

 

The SDPC vortec intake is the same as the Edelbrock, but $100 cheaper.

I would recommend you research options for modifying the Vortec heads for higher valve lift, otherwise you're going to be limited to about .450" of valve lift, which will pretty much eliminate every good cam on the market.

 

I work for advanced auto parts so i get 20% off so an edelbrock manifold would be the same price. I know about the valve lift restrictions i just dont know what springs to get... I want to decide on a cam first though before i get springs.

 

Ok did the carpet today it looks awesome. Ill post pictures tonight. Also im going to go spray a satin clear coat on the interior pieces which ill post as well tonight

 

Here's the before and after carpet pictures. Steam cleaned the carpets first, then vacuumed them, and finally sprayed them with duplicolor vinyl and carpet

looking good! welcome aboard and best of luck with your project.

 

Thanks i appreciate it!!

 

Got some new parts today! Steering wheel, t top bag and seat bracket all for $60


Also got my t top bar off...



Tomorrow i take apart the dash and work through my electrical connections

 

Think I'll be keeping an eye on this build, good start so far.

 

Well took apart the dash and the wiring is chaos just butchered up everywhere. I'm going to pull the whole harness tomorrow... I need to find a good thread on wiring. Anyways ill post some pictures tonight.

 

Here's the dash removal pictures. Nothing cracked or broke but im going to be spending quite some time figuring out the wiring harness

 

didnt get much done today just got drunk and wire brushed a little bit of everything lol

 

Awesome project dude.. That carpet looks amazing

 

Thanks ive got a long way to go still

 

Got frustrated with the wires so i pulled the harness. Still looking for a good wiring thread. I'm also going to convert the car to manual so ill find the wires that are involved in the conversion.

 

Very nice find and you look like you've done this before . Nice work.
Do you mind telling me how you know the engine is a 350 ?

 

First time actually haha, and i checked the casting numbers plus on the block it actually says 5.7

 

Nice.......

 

Ok i got the wiring harness in order. I work all day tomorrow but next time i work on the car will be the first time i get to actually put stuff back into the car. Very exciting ill finally start seeing some progress.

 

Need some help guys

Got some progress done today. Put in a new heater core, started putting the air duct back together, and am now wrestling the interior wiring harness. If anyone knows of any good wiring threads let me know please!!

 

good wiring threads? pretty much anything written by pocket.

 

Could you help me find one, i suck at searching...

 

I went into the electronics forum and searched "dash" up at the top near thread tools. As far as finding pocket's posts, you can try going to 'member list' and going to the 'P' section. I'm not trying to be a ****, but I'm sitting in Afghanistan (with my car in the states, and I'm stationed in Europe), and get on here when I'm bored. As far as cleaning up and repairing your harness, when I did my '91 RS, I used both the Chiltons and Haynes manuals, working a little at a time cleaning up and zip-tying everything together the finally putting it back into the loom. If you can read a wiring diagram, you should be able to find the wires used in the conversion from automatic to manual transmission. Don't quote me (it's been years since I've had a third-gen apart), but I believe most of the wires are already on the automatic shifter, and just need to be moved to the clutch/brake pedals.

 

Looks like you're making some awesome progress on the car.

 

Got a little bit of the wiring done today still a little confused. I think ill be done with this gremlin by the end of the week.

 

looks like i can get a re built vortec 350 motor from advanced (with my discount) for $1200. I think thats the game plan now

 

Do you plan on keeping the tpi set up?

 

Yup just gonna get the edelbrock adapter and a custom tune then call it a day.

 

I plan on doing the same swap I figured it was cheap street hp can't wait to see the engine build

 

yea i was planning on building the engine myself just didnt seem rational or price effective. $1200 would only cover the machine work. This way i get it all done with a warranty. I just want to find a better cam then stock..

 

I've read up on this build a little and noticed a lot of people using lt1 and lt4 hot cam I plan on goin with the lt1 for a smooth idle

 

isnt the lift to high for the stock heads?

 

I think the lt1 stock cam has .447/.459" lift not positive but that shuldnt be too hot for the vortec heads

 

If you find one like that shoot me the link please

 

Here's a good thread you can read up on. 350 Vortec TPI build/swap thread - 88 GTA
