a healthy 308 will sound at least as good as a Chev, if not better. The Holden V8 is well known for having a great note.

Easy conversion, I did it on my previous VH.
Engine literally drops straight in, using V8 mounts. Unplug your 6 cyl harness from the firewall plugs and plug the V8 harness straight in.
You'll need a V8 radiator
If you haven't got a set of aftermarket front springs already, then you'll need a set of V8 front springs.
You can keep your original steering rack if you like. Generally speaking all V8's were standard with power steering, but if you want to work on the biceps, a non-pwr rack will suffice (I kept my non-pwr rack). Will need the right gearbox mount for whatever gearbox you use. May need a V8 tailshaft to fit.

Front discs are the same on 6 & 8 cyl VB-VK. V8 Commodores were standard with rear disc brakes, so you'll really need to upgrade to do things right if you have rear drums.
You could easily knock the conversion over in a day

You may want to check with Vic Raods whether you can fit a red motor to a VH.

I dont think HZ is red. pretty sure they are blue (u shaped egr crossover port) so you can get away with it. just make it look like the egr is working. other than that im pretty sure its just a case of informing vicroads of the change of engine number and your done.

 

[SL/ENUT]

Its red. The blue engines came out in the mid 1980s during the VC/WB/VH run.

 

[ari666]

when i say 'blue' am more referring to the U shaped port. i think Hz had a U-shaped port, so can hook up egr.

That doesn't make it legal though Ari...

HZ had the red motor, regardless of the EGR it's a red motor. Which means, no go in a VH.

 

[ari666]

ok, got my book out. it says "HZ onwards had a square shaped EGR port" which is the same as VK black

HZ was released in 1977 and had:

retarded camshaft timing
EGR
carbon cannister

all to meet ADR 27, which is the same as the VH 5.0 liter blue - option L31. the only real differences i can spot is that the HZ has a comp ratio of 9.7:1 and the vh 9.2:1 the HZ had 170kw@5000rpm and the VH 126@4400

i cant see any problem with fitting that partiular red engine into the VH. paint it blue if it makes you feel better. but it meets ADR 27 and thats all they care about.
