I cut the wires off a bad oxygen sensor then got a quick pack on eBay and installed it. I put the extension on the right-hand side which is a terrible design by GM to simply change the sensor out. Next time won't be a problem.

I gave that a thought... I actually cut the wires from a bad one and mocked it up.... still about 10-12" short... The connection behind the motor mount is just stupid!! If I could get that un-done from behind there, I might get some length out of it....

Yes it is stupid. That was pre-assembled before they drop the motor in on the assembly line. Just take out that 45° angle brace and some other pieces in there and you can get to it more easily. Without some disassembly it's impossible to get that thing unlatched. I have stock manifolds by the way.

Tell you what, the other day while digging through my parts stash I came across this 20” O2 extension I had picked up from Ron Woods many moons ago. You’re welcome to it if it’s what you need.Attachment 8153

So I got both the left and right side headers installed today and of the 32 bolts, I got 29 in. I used a combination of the factory bolts and shorter allen head bolts I had from many years ago when doing the headers on my 92 Z. Pays to be a pack rat sometimes....

On the last one, not really sure how to decipher the numbers on the block, or what they mean....

The number your photographed is 10ZSH X00625 0006.

The 10ZSH is a Mercury Marine tracking number for a 1990 engine with A/C. The X0 idesignates the build year 1990. The 062 is the month and day, June 25. The 0006 shows it is the 6th build of the day. The car serial number is found in another spot, on a block at the back of the block on the passenger side up near the valve cover. It will show something like this: 1S5 800409 (from a 95 #409) along with some other numbers. The "800409" is the car's serial number. OK I cheated--It's all on the ZR-1 Net Registry home site under "Information/General/VIN Numbers". --Bob

Awesome...thanks Bob!

Here are a couple of pics showing where the VIN shows up on the engine. It is on the vertical block just behind the rear cylinder in the engine picture. The numbers in the other picture are a bit hard to read but it shows #409's proper engine number. Of course it is quite easy to read these numbers when the block is out of the car! --Bob
