Enlighten the ignorant please.
Can't it be fixed like any other engine. 😕

Depends on your definition of 'fixed'... There are some normal-maintenance items, starter, seals, etc. that are easily replacable.

Heads, block, other large cast engine items are out of production and not likely to be remanufactured. So you're looking at either getting someone to one-off a compatible part (super hard considering the tolerances and operating specifications of the LT5), or finding the same part salvaged, which is nigh impossible on this car.

If a ZR-1 breaks, it's usually easier to just go buy a new one.

It was a limited production quad overhead cam engine (not even actually built by GM, IIRC). Replacement parts are hard (expensive) to come by if you can even find someone who knows how to work on the engine.

it's DOHC... never heard of quad overhead cam...

i hope it's not this quad overhead cam...

and AFAIK the exhaust is made of titanium (either this or the ZO6)... and the car costed something upwards of $50k.

In the red section of your first link it says "four overhead camshaft".

That means there is a total of 4 cam shafts.

from the beginning of the page:

"ZR-1 known fondly inside GM as the "King of the Hill", roared to life in 1990 with an all-new 375 horsepower LT5 engine under its hood. Designed in a cooperative effort between General Motors and Lotus, the LT5's dual overhead cam, 32-valve design made Corvette the talk of the automotive world..."

so it's a DOHC compared with other chevy's which are OHV...
 
The LT5 has four camshafts. It's quad cam, not DOHC. Well, technically it's DOHC, but there are 2 heads, so 2 for each head.
 
I'd take a regular C6 over the ZR-1. The only reason I'd take a ZR-1 is as a collector's item. I'd want to drive it, and the C6 would win hands down in that area. It would be probably a bit faster, handle better, ride smoother, have more room, and get better gas mileage to boot.
 
I'd like to see a shootout on them. I have a feeling that a ZR-1 could beat a C6 on a rolling 100MPH start - the ZR-1 has one of the best high-end powerbands of a production car still. It has a phenominal ability to breathe, mostly due to the silver spider on top of the engine.

The picture posted isn't necessairly the best example of a ZR-1 either. The later ones look like the later Corvettes, with the rounded bumpers. The only real difference between them, aside from interior and wheels, is that the rear bumper is 3" wider - the widening starts at a small angle from about midway down the doors through to the end of the car.

It's also the only car I know of with a power key. You've got to turn on the full power of the car, otherwise it does something to cut HP roughly in half, don't remember what exactly. Shut off half the valves, maybe?

Man that Quad-4 DOHC engine is a beast. It was way before it's time. The Beretta GTZ was stated to run a 16.0 or 16.1 in the 1/4 by Motor Trend, but that was because the retards didn't know how to drive it, and that it had an insanely high redline for it's time. People were running 15.2's bone stock, which was unheard of out of a 4 cylinder in 1990. With some exhaust and intake work, and a retuned computer it ran in the 14's easy.

For years, the Callaway twin-turbo Vette (RPO B2K) had the distinction of being the fastest production convertible with a factory warranty available. At ~382HP, it's still up there.
 
zr1 is still a monster. But the C6 is more efficent and refiend that I think it will give the zr1 a hard time.
 
It is a quad cam, designed by GM, Lotus and built by mercury marine.
Rare and god-awful expensive to repair.
Seems that I have read that problems are normally huge if experienced, thrown rods especially.
Replacement are near impossible to find, and run in the tens of thousands.
ZR1 would be a great car if you could afford to park it and let it appreciate. You'd have to really be rich (or maybe not too smart) to take a chance on driving it.
I saw a video recently of a c5 zo6 racing a new c6. The z06 did not start to walk away from the c6 until they were doing well above 100mph.
I doubt the ZR1 could touch either. The ZR1 only had a 4.9 0-60 time. Very fast for it's time, but just in line with the C6 and c5 z06, and much slower than the new Z06.

In my opinion, the C4 was the only ugly Corvette ever made, and it's really ugly. The C6, on the other hand, has great lines. That's where I'd head.

The ZR-1 had a "valet" key, you could toss the key to a valet, and it would shut off half of the valves, basically breaking its HP in 1/2.

and the pic i posted is of a 95 ZR-1 IIRC.

the ZR-1 was a 4 cam, 32 valve V8 in 1989 producing 350 (i belive) hp, and was the fastest production vehicle of its day. by 1995 they had hit 400 hp.

(they are the GOD of corvettes, right up and next to the current z06)

My favorite Corvette engine, Lotus did a hell of a job on that engine...
