Yes, the 5-litre EFI Holden V8 is the perfect choice for the HQ-WB Holden.

The only other advice I would pass on is for the fuel system. Again, copy the factory set-up, they work well.

Instead of mucking around with pick-up pumps, external pumps & surge tanks etc., just fit a factory VT fuel pump MRA assembly. MRA is the acronym for 'Modular Reservoir Assembly'. Basically it is the pump, strainer, surge tank & fuel gauge sender all in one. They are quiet, simple, cheap & reliable, they tick all the boxes.

If you are using the existing Holden ute/van/tonner fuel tank, cut & hole in the top & weld in an adaptor ring. These you can purchase aftermarket & it allows the VT pump unit to drop straight in. They even have the extra fitting for you return line to attach to.
