1986 IROC-Z Build Thread (lots of pictures!)
Hey all, my name is Kevin. I've been a member here I believe since 2008 when I first purchased my 86' IROC Camaro. You may have seen it around here and there on the site. The purpose of this thread is for me to centralize all of my efforts in keeping up-to-date pictures and progress reports on the car. Like a lot of you, I have poured a lot of time, energy and MONEY into the car over the years to get it where it is now. It is definitely a never ending project even though I completed a lot on the build this spring already. I have plans in the next few years to bump the heart to a 406 sbc, but that will again take time, energy and a lot of MONEY that I don't have right now (my wife and I are ready to buy a house finally!)
Here is a build sheet I put together of how the car stands now, followed by some recent pictures.

This picture was taken a few days ago and is how the car currently sits. It kills me not to have a garage to keep this in right now - it spent all winter outside under an all-season California car cover with gust guards.
This is how the engine bay currently sits. I'm pretty happy with how it looks these days. You can check out another thread I made here to see how I sprayed the engine bay with the motor still in. Whenever I get around in the future to taking it out again, I'll do it up proper. I'm hoping I have a son in the near future that wants to work on cars - it would be a great excuse to tear it apart again
This is an HDR picture my wife took of me. We share a common interest in cameras and have been having fun recently learning together. She loves taking HDR shots. We use a Canon T3i with various lenses for all of our photos these days (50mm 1.8, 85mm 1.8, 24-70 2.8, 70-200 2.8)
We continuously try and improve our photoshop lightroom skills:
Not too many weeks ago, this is how the car sat...
...while it waited to receive:
Now I'm back to rowing through 6 gears!
The interior still cleans up pretty well, too:

Re: 1986 IROC-Z Build Thread (lots of pictures!)
Not too long ago, the car was included in the 2012 MSD parts catalog, its claim to fame!
It's only been in a couple of shows, but has taken prizes both times:
Blew up the stock 10 bolt for the first time on the way home from the 2009 award!
Did that a few more times... I still need to get myself a 9" haha.
This photo has received a lot of attention over the past couple of years:
And about 2 months prior to that, it looked like this after someone hit the side of it. Gave me a great excuse to finally lay new paint on it!
And here is what it looked like when I first saw the car before buying it in 2008:

very nice car man. What kind of air filter is that? I see you have an air gap and a 1" spacer under a stock hood and i'm looking for something that will fit my car

Re: 1986 IROC-Z Build Thread (lots of pictures!)
Even with the air gap intake, I was still getting vaporization of my fuel at the track on a hot day. After adding the spacer, the issue was gone. I was previously using a 3x14" filter, took that down to a 2x14" K&N filter with a drop base and a Summit powerlid pass-through top.

Re: 1986 IROC-Z Build Thread (lots of pictures!)
Well you definitely haven't seen my Camaro around. I bought it a year ago and have yet to finish the rebuild enough to get it on the road. However I drive probably the only pontiac vibe'rator' with a racing stripe though... I thought I recognized your car in the beginning before seeing that your in Binghamton. Build thread is here for mine should be closer to finished this summer. https://www.thirdgen.org/forums/memb...-here-she.html

Thank you!
Haha, that's what I like. I like nice, clean looking rides that perform very well. I feel like what I've done with this car is give the trained eye some pretty solid clues that its pretty quick. Anyone just glancing wouldn't give it a second thought.
Thanks!
I'll check your thread out for sure.

Maybe I missed it what does it run? I just got my 255/50/16 Mickeys on this week, it is such a night and day difference it's ridiculous... Probably the best single mod I have ever done to a car. I can actually take advantage of my torque converter now!

I agree on the Mickey's - even with my 6 speed, banging through the gears, the tires do not bark, there is no drama or hoola dancing, it just dead hooks and goes. Perfectly compliments the SPEC stage 4 clutch that really moves it off the line.

Here is my previous best run:
New 1/8th mile numbers and video should be up sometime this coming Sunday. Pending weather, I'll be heading to the track this Saturday mid-day to get some passes in. Hope I don't bust up the 10-bolt yet again!
Just a small plug for the group - ThirdGen-Nation has elected me as their featured ride this week on facebook at https://www.facebook.com/ThirdGenNation?fref=ts. Check them out!

Just a test and tune night. Decently quick for what it was.
Thanks!
As a follow up, I did go to the track this past weekend but was fighting fuel issues while there and the car didn't perform well - ran about the same as before. Once I get the fuel issue sorted, I'll head back. Ordered a wideband to install this weekend.
