Big Block 3rd Gen goes the distance on Power Tour
I thought you guys might be interested to know that my '87 IROC with a 427 big block went 1,700 miles on this year's Hot Rod Power Tour. It sat through grueling traffic without overheating, ran through the curvy Blue Ridge Parkway on it's drag radials and skinnies, traversed train tracks without hitting the exhaust, ran bottom 12's at Gainesville and South Georgia, and, at the end of the Tour, ran 11's at Englishtown. I'm a happy camper.

I have 275-60-15 Nitto Drag Radials on the rear. The wheels are 15x8" with 5.5" backspace. The inner wheel well had been clearanced by a previous owner in order to fit L60-15 MT Sportsman SS tires. The passenger side fender lip required rolling due to a slight rear end offset to the right.

I just added up my receipts. I used 145 gallons in 1,754 miles, so I got 12 miles per gallon. Not too bad for a big block with a 750 Holley double pumper, TH350 (no OD), and 3.73 rear gears. I spun it on the highway 3,000rpm all day long. It actually gets better mileage than my stock 454SS pickup.

What's your best pass to date on spray?I'm curious,as I just finished the swap to a similar 468 in my car.
I'm itching to get it to the track,just wanna get things dialed in a bit better first.

The cam is unknown because a previous owner built the motor. My ear tells me it's approx. 240-250@.050 on a 108 or 110. Idles at 1,000rpm in neutral and 750-800rpm in gear. Pulls hard to 6K+.

But his end $ figure can be trimmed considerably if your not looking for perfection.If you want an original,unmolested car w/ absolutely flawless paint and interior,than a low mileage survivor is the way to go.You'll never match what was assembeled at GM by doing it at home.
My car is a lesser version of Neil's,I've owned it since I was 17,and admittedly have a helluva lot more than $13k in it.But that is from years of engine builds,tranny swaps,tore up stuff,etc.You gotta figure,I've owned it 14 years.
But in it's current form,I'm confident it could be built for a ballpark $7500.That's figuring buyin a clapped out 3rd gen for around $1500,and doing all the work yourself.
Granted,for some reason my aftermarket fortified 9 bolt chooses to live,and I don't know how.But as it sets,I built the engine myself,so parts/machine work is the only expense there.I painted it myself,but Maaco could probably do as good a job,just a little more $$,and my interior is fairly sparton.I had the seats recovered in 97,they could damn sure stand it again.And my stereo consists of a Pioneer CD player and whatever Wal Mart had on sale for speakers.
My whole point is,do what you can afford.Put your $ in the go,it's way more enjoyable to pound on it than it is to clean on it,at least in my opinion.If you watch your pennies,you can build a fast 3rd gen that looks presentable,even w/ a bigblock,for a reasonable sum.

I sure hope you aren't offended by what I said,just don't wanna see anyone afraid to build because it has to be perfect.
Your car is beautiful.I hope that someday I can afford to turn my car over to a paint shop for about a year,and upholstry for 3 months or so.But until then,I'm gonna enjoy beating the **** out of it.

I definitely saw you and checked out your car several times on the tour, GREAT car!!!! My car also made it all the way. I had to drive it from Maine down to Florida, and then all the way back up, but she made it! I wish I'd gotten a chance to chat with you a bit, but major props to you on the car and bringing it on the tour. That was an AWESOME time!!!

Englishtown has just been around for a LONG time and is known as one of the better kept up tracks so all the small tire street cars work on it well.

Nice job Neil, we went over 2100 mi between 2005 and 2004 on the Power Tour and had a blast. I would recomend to anyone that if you have a chance to do it, go ahead.
This is a pic of my car at St. Louis Raceway when the tour was there in 04. I got around 22 mpg with my car ....not counting screwing around
