Were 1980s cars really that bad?

For the times, an L98 IROC was pretty quick. The only options this one did not have were t-tops and the Bose Stereo. Otherwise, this was my first 'loaded' car.

I special ordered this in 1989 and still own it. It's a 1989, G92, LB9, 5 speed, with N10 dual cats, oil cooler, Aussie BW 3.45 9 bolt and DX3 decal delete. I figure if you put it in a time machine and sent it back to 1969 it could hold it's own on the street in a straight line with most muscle cars of the day and annihilate anything from anywhere on a curvy road.

You do know that most of that was due to tire technology right?

My Pure Stock 71 GT-37 ran a 13.25 this weekend at Norwalk and still has more in it if the driver can get better - there is no way in stock form your IROC (or mine for that matter) will ever do that.

Don't laugh.

A friend had a '88 or 89 Cavalier Z-24 5 speed. 140 hp stock. He put a cold air kit on it from K&N and some other mods from the gm catalog. I believe he changed the camshaft, did some headwork and exhaust mods and gearing.

That thing would get up and go.. of course it was probably a thousand lbs lighter than the comparable cars made today

I do.

Also, I'd say Pure Stock cars are probably running a bit sharper than they did off the showroom floor.

Just out of curiosity, why is that? Understanding that there's a difference between Pure Stock and actual as-delivered-off-the-showroom-floor vehicles, a Pure Stock legal roller cam 5.0 will run low 13's, so what is it about the TPI Chevy that would keep it from doing that?

Off the top of my head, Pure Stock allows an added point and a half of compression, gear ratio changes, bigger exhaust, carb tuning, bigger tires, etc.

That's my understanding as well. A roller cam 5 speed Fox coupe with those mods could crack 12s with a very good driver before the factory Goodyears become an insurmountable obstacle, so I'm curious as to why a TPI Camaro can't at least get in the bottom half of the 13s.

Here's a Motorweek road test of an '89 G92, dual cat, LB9, 5 speed with a 3.45 gear.

This is the fastest one I've ever remember seeing from the day and may not be representative of the typical production car - but they got a 13.9 second 1/4 mile.

There were a number of free/cheap mods on the TPI back in the day, (similar to the 5.0 Mustang), which could REALLY wake it up.
