Hard to tell how its been modified to suit the wb conversion but price isnt bad. Could be worth asking for details and more pics.

So if I want to fit a T5 box will I need an adaptor? do T5's bolt up to the aussie 4speed box/trimatic patterns or turbo patterns?

T5 is turbo pattern..
cheapest way to do it is to buy a vn to vt 5 speed car..they are at salvage auctions everyweek and anything up to 15 years old is stat right offs in nsw..price wise vn vp vr ss 5 speed go at salvage auctions as a high mileage pig/untidy low price 1200 to a tidy well looked after but damaged 2200.. vs vt are generally more expensive because of low ks and also because of the roller cam motor and the blocks are already relieved for stroker cranks..2200 to 4k dependant on damage...
the better wreck you buy will return you money wrecking out the parts you dont want.
you need hq to wb or lh lx v8 sump and pick up..hq to wb engine mount brackets..hq to wb water pump and pulleys.to swap onto commodore motor..

Thanks for that Greg, in regards to dropping a motor into a HZ from a Commodore Vn onwards I would need an engineers report? if I use a red motor bottom end would this bypass the engineers reports

yes you need to comply with adrs for engine number generally..mind you i had a wb 1 tonner with a vp ss motor complete in it and it sailed thru blue slip no engineers report at all,this was only 2 years ago......go figure...:Tophat:

Sorry to hijack this thread but I am very interested in researching this conversion. Its a bit of a toss up between reco'ing the original 253 and the 4 speed conversion that I have or putting a 304, 5 speed and a disc braked diff. I was going to buy a SS commodore as a donor car but I don't know which one, (secret ford man, the sandman Poo's on the sundowner). Any thoughts, links or should i just stick with the original running gear?

Wow awesome, thanks.

if anyones interested i know where there's a NEW (still on pallet) VT roller stroker short motor for $4500

i can also get exceptional prices on any of the current Chev engines LS2, LS3, LS7 (427), LS9 (SC 6.2) and pretty much anything from the GM Performance range

im putting in a vn 304 into my sandy but instead of injection have gone with the carby so got a harrop manifold and reco quaddy and she runs a dream the motor has been fully rebuilt close to factory specs, just a better cam and some flat top pistons to give a little extra grunt something to consider as you dont need any computers or loom but still get the newer motor with better flowing heads, also have a 5 speed to go behind it and a 9 inch (which im looking for a 3.5 lsd centre)
