Hey Guys!

Is there a particular state of tune for a 4.5 V8 Hotwire that went into the 450's?

Heads? Induction? Mine has the enlarged throttle body, but I know very little else about it.

The heater pipework is a bit odd...Something to do with the air-con. perhaps??




T.I.A.

If its an NCK engine then Dom Trickett at Powers Performance will have the build sheet for your engine. Give him a message.

Out of interest is it cross bolted?

I have an NCK 4.5 pre-serp in my Griffith and that’s cross bolted but not sure if they all were.

And yes Dom can tell you the original spec if you have an engine number

The NCK number is usually stamped on the front of the engine just below the oil filler....

You could also try the usual place for the V8's number, on the block flange just next to the dipstick.
Some blocks still have the Rover serial with the NCK number, some just the NCK number.

It's says 3.9 not 4.5 . Not nitpicking, it's a genuine question.
Why is that 3.9 ?

They used those plenum chambers from landrover & modified the inlet size by boring & sleeving. As I understand it.
