Any blue or black carbied 308 or 304 will do you (VC/WB through to VL). Easiest to find will be about 11/81 onwards as all carbied 308's and 304's after that are 4spd blocks. Most earlier ones (2/80 through to 11/81) are TH pattern. You'll probably get away with a late red 308 too (ie HX, HZ, late LX or VB), but again many of these are TH pattern.

Here's a VL 304. You'll just neeed your WB 253 sump, pickup, exhaust manifolds and engine mount adapters. Plus the flywheel, clutch etc.

If you use a VN engine you have to run VN EFI etc in NSW. The only problem with a VL engine is by the letter of the law you need to run catalytic converters and a ULP filler neck. But no-one will really know, when you get a blue slip they probably won't even know. Just tell them it is a 308 from a 1984 VK. The rest of the pollution stuff is the same as what is on a WB.
