    no chance ever getting it regoed with the carbied v8.. if u want an 8 put in a injected 5 ltre as its legal if u get one out a vp or l8ter and it will produces more power then the carbied 8 or just go buy another v6 for 500 bucks

    heres a trick question and something i had thought about doing a few years back before the stroker and turbo kits were available for the v6 but what if you grabbed a 253 and placed the 304 efi gear on top?

    Can be done, few issues though. Because the port order is different between the carby and efi V8's, you have to use the VN onwards heads and cam before an efi manifold will fit. You also have the issue of most (if not all? Can't remember) 253's being trimatic pattern, so you need to modify the block to fit the T700 box.

    Once you've got all that out of the way, it's still probably not legal. I'm not sure how true it is, but I keep getting told that you can't use pre-emissions control blocks in an efi application because the RTA ID's the engine by block number, and if the block number is for an engine that doesn't meet the emission standard applicable to the car, they assume that the engine doesn't meet the standard. Even if you've brought it right up to efi spec. Seems stupid to me, but in my experience the RTA is stupid, so I'm perfectly willing to believe they'd do that.

    For what it is worth, addressing the OP: yes, you can fit a VL spec. carb. V8 into a VP because the emission laws applicable are the same. Why you would want to is another question.

    The EFI heads onto a 253 (in a VP) is definitely not legal. Bringing an earlier 308 up to VP specs. can be OK, providing all the emission parts are present.

    You can do it if you run straight lpg, or a VL 304 motor (which will be slower than the V6). Apart from that you can do the sensible thing and just put a injected 304 in it which is stronger/faster/better, just better than the earlier motors. Probably the best and easiest option would be a ecotec

    Where are you? I have a fresh 5 Litre VN (Complete car) that would be perfect for the project. Body is fair (no damage just rough) but mechanically it is great. PM me if interested.

    Cheers,
