vh commodore wagon
thanks will do... but for the cost of getting it all put in i could get a bit of power out of the 202 (which hotted up soundS just as good as a v8 :whistling in my opinion) Has any one got any links to people rebuilding their blue 202s? any help would be appreciated!

cheers...mike

I would work on gettin the V8 into the VH rather than doing up the 202. 202's are nice but all the work that you are going to do to the blue motor is already in the V8. And the V8 would get more out of it.

And nothing beats the sound of an actual V8 matie :D:D

Dunno what the Valaint forums would know about it>?. But there's been plenty of old Holdens with the p76 motor in them so it can't be impossible. Would need an engineers certificate and emissions test in a VH that's the major problem. It's much easier in the semi modern cars to go with a modern injected motor that bolts straight it (304)

Yeah, greenfoam stole the words out of my mouth.

A mopar forum isnt going to know much about the conversion ,but will know more about the engine no doubt. Also this forum has heaps of Valiant fans and older members who will know there **** on the subject.

It would be a sweet conversion, dont get me wrong, but by the time you add up costs, engineers, labour, time and mucking around getting parts, making stuff fit, it would be cheaper and easier to use a 304 EFI setup, or just a nice 308 V8, saves the conversion, emissions and engineers (304 block conversion needs engineer) and can still make great power, and economy cheap.

Try looking up some Leyland or B.M.C sites . The aluminium V8 in the P76 sounds awesome with a sports system and extractors . This motor was also used in the Rover as well . The disc brakes on these cars were pretty good too . Heaps of them were grafted onto the HQ holdens

The 304 inj is supposed to be engineered for the fuel lines, but I've actually never heard of anyone not being passed at vicroads for the injected conversion straight up

The P76 engine is a derivative of the Buick/Leyland/Rover/Landrover/TVR all alloy V8. Chrysler have nothing to do with it.

It should be an easy conversion. You'll need to fabricate a new set of engine mounts,gearbox cross member and custom tailshaft. The P76 were pre ADR 27a so you'll have to rig up a PCV, EGR valve, evaporative control system and intake air preheat system. ADR27A did not have any specific tailpipe emission limits apart from noise level so you only need to have the systems in place.

Of course you will have to get engineer certification.

I have seen one in a LH Torana years ago but never a Commodore. It would be a great setup in a VH, you could also adapt fuel injection from a late model Rover.

Thats what I thought when I first read P76, then everyone else was talking Valiant/Chrysler so I was a little confused, but 8 hours sleep in 4 days I thought I shouldnt think for myself lol.
