Nice. I have a 87 I've been wanting to tinker with. Now I know what NOT to do ! Lol

[brandonbman]

$3k for that IROC in that condition? I’m calling bs. Only in magic tv land.

[tyleravery]

The stock 305 could have made 300 on the bottle and saved the time and money..This makes Trick Flow look pretty bad.

[of]

This format is just like a rehashed saturday morning episode of TRUCKZ from 1994. Aluminum heads and on the squeeze it didn't make 300hp. I'm surprised this video got uploaded on the internet. LOL

[steveseattle]

I have never seen so much work and parts result in so little power...


Full engine swap, aftermarket heads and cam Plus NOS and it didn't even crack 300 HP?!

I graduated HS in 86 and my parents got me an IROC Z for my grad present. It was identical to this model except the paint job was midnight blue. T-tops, same wheels, same motor. Black leather interior and I put an Alpine stereo system. God I loved that car. It was so quick, so head turning. Maybe I will get another for my midlife crisis.

[Shane-Singleton]

That car is pretty darn clean. I'd have paid $3000 for that thing any day of the week and twice on Sunday!

220rwhp out of a 350 with trick flow top end kit? ...something's wrong with that motor.

[CamaroRick]

I bet that things got around 5:1 compression

[DMD]

This is like a horsepower tv episode that wouldve aired 20 years ago.

[chemicalspore]

I gained a 135 hp in my LS with just a head and cam swap. This is unethical.

[techsir]

HOLY CRAP!!! Was obsessed with this car for years and NEVER found one in this good of shape for less than 8K.

[woofer]

Should have just put nitrous on the stock engine and saved alot of money.

[IrocinZ]

Disappointed you all didn't use the TPI...

[jmv]

For the money spent and stuff that got swapped, I'd rather do a junkyard 6.0 and carb it.

Figured out why the numbers were so disappointing.

The cam they're running is tiny. The cam info they give in the video is for Trick Flow's 31402002 Hydraulic Roller Cam. Which is pretty aggressive and you can tell that's not what's in the car when you hear it idle and pull.

They're running a flat tappet, likely the TFS-31401000.
A mild flat tappet:
- 212/214 @ 0.050" lift
- 0.443"/0.449" Valve lift with 1.5 Rockers

With such low lift, lazy lobes, and short duration teamed up with the stock IROC exhaust (stock y-pipe is the killer)... 230 whp and 276 ft-lbs is about what I'd expect through a high mileage 700R4.
Roughly 270 hp and 330 ft-lbs at the crank. Sounds about right.

The heads can't even be taken advantage of due to the low lift.

[OCofthe]

What did I just watch? With those heads and cam, it should have been around 400hp.

[ragnarfoxtrot]

Heads, cam, intake, ignition and nitrous and still didnt break 300hp, that's weak guys. Makin chevy look weak. 🤦‍♂️

[nbowlingtrio]

Nice no rust body and wheels! Great platform for a sleeper build. Glad to see that your not going crazy and putting a five hundred horse engine in a chassis that not prepped for that kind of power. Awesome video guys

What a blast from the past! I owned an '85 Yellow TPI 5.0 IROC-Z that eventually was stolen, and then replaced it with an '87.5 Yellow 5.7 TPI IROC-Z. The yellow used on both cars was actually different. I'm not sure when it changed but I suspect '85 and '86 yellow were the same, and '87 was different. My '87 had tan leather, Bose, and neither had T-tops. Good times!
