My 5.0 TPI 88 Firebird Formula is a high-miler with a bit over 295K miles on the clock. I suspect it may have a leaking injector, because on occasion it doesn't start as quickly as I'd like. Otherwise it runs fine and passed smog last year when I bought it for $600.

86,000 original and I'm the 2nd owner. Had 46,000 when I bought it 6 years ago. Not too bad.

 

155,000 on my 88 GTA L98....all stock.....runs strong and rips up the rubber nice......about to change the injectors to LT1s. Next year if money permits it will be built into a 383 or 400.

 

about 63,000 on the L98, which was rebuilt at 30,000 and given forged internals and bored .060 over. 150k on the car.

 

176,000 runs strong burns no oil. Had to have a valve job, worn guide, anyone else?

 

about 18000

 

70,000 miles and smokes like crazy when i start it.

 

113,000 original miles, used to smoke on start up, replaced valve seals, doesnt use a drop of oil now.

 

Bought it with 20,000 now has 23,000. Smokes little on start up due to dried seals but going to take car of that this winter.

 

212k mi on stock motor never opened. Tranny has been rebuilt. No smoke but there is a ticking sound on the passenger side of the block. I can't tell if it is an exhaust leak or valvetrain.

 

152k on LB9, motor's never been apart except for 1.6rr's 50k miles ago Still no smoke on start up and it runs 14.20's every weekend

 

220,000 miles. 189k on the original 305 (still running perfect when it was pulled in favor of a 350).

 

just knicked 10k on rebuild, car itself has 84k!

 

140,259, runs very strong , no smoke on startup, and doesnt use any oil AT ALL.

 

131,600 then rebuilt (my choice). now trying to get more than the mere 300 miles on it since... ever heard the saying "if it ain't broke, don't fix it"? maybe i shoulda' listened...

 

hey iam thinking about rebuilding what type of problems you been having since u rebuilt yours?

 

Almost 150000 miles on original 305 TPI, trans and axle.

Used to smoke on startup, had top end rebuild with new valve seals, nice n clean now.

Still a lazy starter, think I've probably got a leaky injector or weak coil.

have a 305 TPI out of my 86 IROC- 127k miles, and it burned a small amount of oil- 1/4 quart a month. but no funky noises or anything and it ran great before removal.

swapping for my zz4 with vortecs and keeping the TPI.. $787 on a vortec baseplate and high flow runners.. DAMN it better be worth it..

 

mechanically, really none. had some electrical issues that took forever to fix, some are still out there. the rebuild itself went pretty well, actually. didn't really do any major mods, so mine was pretty straight forward for the most part. spent a lot of time cleaning parts - even all the bolts. i did most of the work myself with some help, of course. then the trans was rebuilt, same with the heads, and block. i had the block built back up since i didn't have the tooling for it. then i assembled everything together and put it all back in. like i said, mechanically there was never a problem. it was my first time doing a lot of that stuff and i asked a lot of ?'s on this board. when it was all said and done, it fired right up.

 

about 5,000 miles. New Jasper Reman.

 

Just Bought my 1987 IROC-Z in September. It has 46K on a Fresh rebuild. 60 over, cam, hardened rods, springs, valves, lifters the works.... 415 HP at the Engine and 350 at the rear...

 

0 miles on the new engine so far and the old one had 64k on it and had very bad piston rings on nr 8 and 6 cylinder.

 

3K on the new 383, 85K on origional 700R4

 

I've got you ALL beat. My '86 has over 87 trillion miles. Follow along:

Earth travels around the sun once every year. The Sun orbits the galactic center at a rate of 514,495.3 MPH, meaning it travels 4,506,978,828 every year. Just for ease, we'll call that 4.5 trillion miles. Since my '86 was built in July of 1986, it has traveled 87,134,908,984.7 miles.

Given that my odometer shows 49,148 miles and that many of yours show many more, and that approximately half of all your accumulated miles were in roughtly opposite directions, most of your actual mileage traveled has been erased. Meanwhile, my old '86 just keeps piling up the mileage, all while sitting under the dust cover in the garage.

How's that for technical content, in an otherwise non-technical thread?

 

Just over 125,000 as of Late September on my Z28

 

180000 only the tranny has been rebuilt, motor never opened and no smoke

 

247,456 and still runnig strong. 91 z28 convertible. No mods yet until I but the wife the big diamond I promised once.

 

I bought my 86 trans am in 2003 with 72,000 miles and now has 80,000 miles.

 

77000 when bought 3rd owner, smokes when started, and a month after i bought it the trans was toast. 79000 now

 

I have 194,450 on my 88 GTA.
The valve covers have never been off the motor.
It does smoke on start up but that is all ( has done that since I bought it years ago).
Just had the tranny rebuilt in September but the motor is still running strong.

 

14000 when I picked her up now I am at 18375 all original!

 

125,XXX smokes on start up
17.5 miles on rebuilt 700r4

 

269,9?? miles, daily driver, first and last owner, ordered Nov 85, Received Mar 86. Motor and trans never opened. The usual replacements - starters, alternators, water pump and so on. Got some minor issues but starts and runs well every time.

90,000 on my 91 Z28 LB9 5-spd. I'm the original owner, ordered it in June of 1990, finally picked it up that Sept. Just replaced stock injectors with SVO's and fixed external oil leak. No smoke at start up. Original rear end & clutch. Gone through several alternators.

 

40K original.

 

OD says 150k+, but it's more like 145k. I'm waiting to put a new tranny in, but this ones not ready to die. I already blew up the old 9 carrier, had a series 3 rebuilt and larger gears.

 

95678 miles.. only 600 or so this year. Engine runs strong and tranny doesn't slip a bit. Doesn't burn oil anymore, mostly just very rich on startup.

 

157,000 or so.new trans. ,maf.Still starts and runs great.Best time 14.17@95mph all stock except trans.

 

167k on mine...hopefully I'll have it running again soon...

 

I've got 128,000 on the ticker and it still gets pretty hairy when I hit the go-go pedal. At idle I am running about 700 rpm's and 30 pounds of oil pressure. She is certainly built to take it. Although I smoked one rear end out of her already... my bad.

 

The original motor in my 'Bird had 203,000 on it when I bought it. It might have gone longer but I didn't give it the chance.

 

275k on my 88 gta, stock shortblock and heads short of putting new valve guide seals on. daily driver and will stay that way, dont like garage queens

 

136k at time of purchase, still 136k on the clock... have done a lot of work:
