NL or NP blocks are you actually asking Ken, as NL is a "gtr" replacement block under warranty. Gary.

The August 72 XU-1 I used to own was first registered in NSW in 1974 with an NL block. I believe it was raced before then, probably why the original JP block was replaced

Hi Ken,

Cheers Kev
Kev do you know if it was ever documented?
I know there is some paperwork floating around, not sure if it’s yours or not
Cheers

I'm just going off the above post thats states his 72 xu1 had an NL replacement engine in it
No reason why someone couldn't use an NL block in their XU1. Plenty of XU1 have had QL blocks installed as replacements. That said, anyone who would pay big $$$$$ for an NL block to use in an XU1 would have rocks in their head when they could grab a QL block for a dime a dozen and it will be just as correct as an NL block as a replacement for a JP engine, which is not at all.

If you want to make some money out of it advertise it as a warranty replacement engine for an LJ GTR or a HQ or HJ Sandman. If it is cast in 1974 it would suit any of these, and the silly $ changing hands for cars like theses today someone might be silly enough to pay a really good figure for it which is a good windfall for you. An NL in an LJ GTR is far more desirable than any other non-original garden variety JL engine.

Are you saying an NL was fitted on the production line?

Won't have happened. An Nx engine is a Service or Warranty engine fitted to a car later normally at a dealership and sourced through the Nasco division. And there will not be "factory" evidence as GMH didn't record engine numbers in cars at the assembly plants, the engines that were in cars were recorded by the dealer when they sold the car. I have seen NL or NP engines in the Service/Warranty report as that was what was in the car when it was sold as the dealer obviously had to replace the engine probably to a demo. There is one in the LJ records somewhere. There is also examples of where a dealer has swapped engines between cars before they sold them, one big example is where a dealer swapped drivelines between a HQ LS with L30 engine and a (from memory) HQ V8 auto panel van, the QR engine is recorded in the Service/Warranty report against the LS and the van with the QU engine. If you scrolling through the LJ records you find heaps of engine swaps and many data entry errors, and the NL or NP I was referring to.

Was a warranty replacement Dave...
Well in that case it is totally incorrect to say it was 'used in an XU1 from factory'
It was dealer fitted, nothing more.
We are to assume this XU1 must have been a 1973 build for it to be fitted with a 1974 cast dated NL under warranty?
In which case there is no excuse really for the dealer installing an NL block when NP blocks were still readily available at that time for warranty replacement.

Assumption incorrect mate was a 72 XU1...
OK, thanks Ken. Facts are better than assumptions.
Still same deal though, if an NL was fitted under warranty. NP blocks or shorts were readily available for warranty replacement in a '72 XU1.
