The car im looking at is a VH with a carby L98 and 6 speed conversion. Registered as a 253. Im assuming the usual emmisions gear, cats, charcoal canister. Anything else specific that I should be looking out for that could cause troubles with getting it all approved? Im in Perth.

And also have a read of this maybe if you haven’t already http://www.commodoresplus.com.au/forums/topic/vrvs-ls-engine-conversion-general-information/ This reply was modified 4 years, 4 months ago by VRSenator065.
