I always felt that GM missed the boat in the 80s... My idea was to take the IROC Z, put the 1LE suspension under it, and a modified Quad-4 with a 5spd. M3 killer. Light, quick, excellent handling.

I am with you on having a extra spring for safety. But Beehives are used as factory equipement on many engines, including all LS engines.

FWIW, fan failures seem rare on these cars and the only ones I've heard of had a hypertech chip or some other ridiculous fan control that had it on too often or 100% of the time.

The relay is probably more likely to fail than the fan.

I pressurized the cooling system in my 91 with a coolant system tester. The system dropped from 19 PSI to 12 PSI in one hour. There are no visible leaks. Should I be worried about an internal leak?

Black means nothing... there is no real technical reason for the diff oil to ever fail. It has no real heat generation and there is no other substance to weaken it.

This is why the manual never states a service interval.

Not to say that it will be bad to do so, just don't interpret black oil as meaning it's failing or dead.

So what's the highest RPM you've seen on your LT1?

Dale,

Just track down a stock LT1 exhaust system... There is a Corvette recycler in Indiana, Tiber(sp?). Or even calling Vette2vette.

The thing is, stock LT1 is a throwaway piece. Hell, wait until the next Corvettes at Carlisle and when they are doing exhaust installs, see if you can snag up on one!

You will need brackets and they are cheap enough. There is a front bracket, two middle brackets and two muffler hangers.

Easy.

Get the LTs and have them adapted with bullet cats to the stock LT1 exhaust.

The installers at Carlisle wont touch anything from the C4 Gen. Only C5 & C6. Redheaded stepchildren again....

I guess the better question, is if you will even benefit from the extra area. There's a point of diminishing returns with exhaust sizing.

I am not sure you are totally correct on this..


Last time I did mine they just connected to the ALDI and looked for codes, no dyno test

However I really think they still do at least randomly look under the car with a mirror..


With my Collector Plates no more inspection for me

That's because the LT4 is an ODBII car.

Yes, but you're missing something.

Let's face it, anyone who just drives on the street and doesn't race should be in a Camry. It does everything better on the street than a Corvette, except break the speed limit.

Top speed is never a consideration, just a "what if"

A good 1/4 mile gear (assuming you finish in 4th) will also be a good street and highway gear.

But I need a dyno curve before I can be your gearing "expert".

you have to appreciate that the biggest hindrence to the L98 is the intake and exhaust. If you go and put freer breathing systems on there, it will allow the redline to increase.

I don't believe there is a physical limiter on the chip (there may be, but I am unaware), because the TPI intake stops revs at about 5100 RPM.

I think I'm just going to have to park it. I can't afford head gaskets right now.

4.10 gears will really wake up your low speed performance, especially in 1st gear

I know, I've thought about it. I'm just so used to 1700rpms at 70mph. Hey, I've still got a Hot Cam to install. It was supposed to go into the LT1 along with your old LT4 1.6 RRs that I bought from you years ago...

In fact, with the LT4, I don't really feel that acceleration until I'm in the 3500-4000rpm range and by then, in a 45mph zone, there's no point in even using third gear as I'm already past 50, .

Found a 1996 for $8500$8500$8500$8500. Black with saddle int, with a Blue Tag ZF6, and not an LT1, but the infamous LT4. Immediately thought this was it. It was in the price range, and it was an LT4, how could you beat that.


First off, the suspension was really sloppy... so was the steering. It rode more like my 96 Impala then a corvette; which is fine for my 96 Impala but not OK for a Corvette. I also found the 330HP LT4 to be severly under powered. It barley pulled for a dead stop and even up top at around 100MPH it just didn't move like my L98. It also rattled like a taxi cab, and just generally was not fun to drive.
What do you think?

That thought enter my mind too but here is what I found today.I went and did some more testing. I used the analog gage last night ( I know better DUH) but today I used the digital. With lights off it drops to 12.2V from ~14.2V with lights on it drops to 11.8V. I did notice the battery reading 11.5V before start up with the key on. So I guess it rules the ground out. Seems a little low on the battery to start and I am leaning more towards the belt/ alternator as the cause.

I'll own up to it ...

I personally would use the LT4 gasket. It has a steel fire ring. As far as I know, it will fit.

I'd just go with the GM stock replacements which are .049" You'll have to do the math to be sure, but I can't see you going beyond a tenth or two of gain beyond the SCR of 10.4:1. In other words, you won't go beyond 10.6:1 at the most. .
