What's the deal with the 3rd Gen?

I've been using this board a lot more lately, and I've seen some 3rd Gen bashing. Can these be fast cars? I mean what I've picked up on is if you have the 5.7L with 3.73 gears, an intake manifold, and a few more items, your car will still be very slow, and an LT1 can take you very badly. Someone please clear this up.

5.7 (l98) in it's greatest stock form from the factory- 245 horses
lt1 in it's greatest stock form- 275 years 93-95 285 years 96-97
add the fact that 3rd gens are lighter, and it's still a close race
a well driven stock l98 can hit mid to low 14's
a lt1 can hit anywhere from mid 14 to high 13 (think i saw a high 13 stock somewhere)
so i mean, both are great motors
it's just that the tpi on the 5.7 really hurts teh top end of the car, in addition to the heads which were designed for the 305 i think
but, with an intake, intake manifold off an lt1, and exhaust, i see no reason why you couldn't take a stock lt1, espec if the the lt1 is an auto
really, lt1's aren't "lightyears" away from l98, they just have an edge, which is normal because it's technological advancement
i fear this could start another "lt1 vs. l98 thread"

I look at it like this, would you own a,lets say a "63 Vette? Yes,you say,but a stock '70's or '80's Vette can run rings around the '63,so what do you say now? Technology just keeps improving in a few years,IF.GM brings back the Camaro do you yhink the 4th gens will be able to keep up? It just depends on you and what you want in a automobile.

Its a gen 1 350. People have been making them fast since the 60s. Open a Summit catalogue, rip out the mopar/5.0,4.6 sections, close you eyes and point to something. Chances are it'll fit on a 350.

WHoever fed you that crap about an L98 with those gears and mods, getting taken by an LT1 is full of ****. Looks at my mod list. Its missing a few items Ihave but it has most of them I thinkn, and and Im carbed now. But even when I was TPI, with those same mods I used to eat stock or light modded Lt1s stop light to stoplight on a regular basis. And that was only a 305.

As previsouly stated its really easier to make these cars faster than it is a 4th gen, because its a gen I SBC. You sacrifice a little fuel economy, but you will save alot of money. If you want you can bolt an LT1 intake up to one, with light modification.

And for the record, I dont think a late 70s or 80s vete will run circles around a 63. Those 70s ones after 72 were dogs. Get the hi-po 327 in the 63 and it should move pretty god.

That LT1 stuff is BS, the L98 and LT1 are close. The LT1 might have more HP, but they never had as much TQ as the L98s or quite the same feel. Mildly modded L98s will take LT1s. Some stock L98s have beaten LT1s before, usually like a 92 vs. a 93. Thirds do have a handling advantage too.

Actually, it's quite easy to make a 4th gen fast. On an LT1, heads and cam and some suspension work will get you mid to low 12's. On an LS1, they will get you high 11's. Or you can bolt on a supercharger and go even quicker and retain complete stock driveability. Not to mention they generally handle better right out of the box.

In stock form from stop light to stop light, the L98 will hang pretty good, but anything longer than 1/8th mile and the LT1/LS1 will eat the L98 alive.

Here we go again...

http://web.camaross.com/forums/showt...t1+4th+gen+l98

Let's keep this one to limited bashing and un-locked.

Anyway, like IZ28 said...handling! I'd rather have a better handling/slightly slower car.

WS6SCharged:
An LS1 will even be a good contender in the 1/8th when going against an L98. Now on the highway....let's not even talk about it.

Oh well, like everyone says...technology keeps advancing. All I have to say is this:
If you put the money that it would take to buy a stock 4th gen into buying/building a 3rd...you'd have one mean 4th gen killin machine

I own one of each, so don't think I'm just senselessly bashing the 3rd gens. Light to light, my GTA would edge out my newer WS6, until I hit 3rd gear and then it was over. At least on the 3rd gen car the engine isn't under 2 feet of cowling.

Hey guys I have a 91 z28. When it had the tpi and l98 motor I modded the hell out of it and only seen high 13's. Changed over to a lt1 motor with ported stock heads, cam, and installed a carb instead of the fuel injection, and now run 11.6 on motor and 10.7 on the juice. So in my case any talk of how the two motors would run after you start modding. The l98 will not stay in the same area code as a modded lt1. Do like I did and keep the third gen cross breed it with a fourth gen , and have power and a car that hangs a curve.

I'm still interested in getting a L98 or LT1, I'm not into the whole quarter-mile cruncher thing. I just want a 13 (high or low, does not matter) daily driver that can compete with all of my friends turbo 4cyl and stuff like that.

either way is easy to do with minimal mods
i say pick the body style you like best and go with it from there
side note- some say the handling on the irocs or 91-92 z's is a tad better than a 4th gen z (i don't know, i'm just spreading the confusion )
but yea, whatever looks best to you, go with it
intake, exhaust, and maybe gears (if you need them) should make whatever you choose, a 13 second car

Does it really matter what transmission I have? I mean I learned manual on my Eclipse and I love 5spd to death. But I really don't care if I can get an A/T into the 13s with a few bucks.
