    Default Can you fit a 350 into a vn ss?

    I have a vn ss and I need a new engine so I'm thinking about putting a 350 in. Will I need to change anything? Or will I be wasting my time? And should I just say with a 304?

    Anyone with any knowledge on this please help me out as I'm little stuck on what to do!

    just stroke your current engine, im assuming you mean a gen3 not a 350 as you'd be unable to install the earlier block unless you ran a efi set up as you'd have zero chance of passing emissions on the chance you were pulled over and defected, someone correct me if im wrong

    My mate has the engine. So I'm needing a new one and yea gen 3 would do! Would I have to change the k-frames, etc?
    Or would I be better just finding a new 304 and stroking it. And yea I'm not sure about all the emissions And shit.

    No point having to worry about getting it all engineered and approved. No one ever has to know that its a stroker engine and no one ever will. I was considering a LS1 for my car but when I found out how much I would have to do to make it happen it just wasnt worth the money or the effort. I hear its 1k+ just for the custom exhaust manifolds for the LS1 let alone mounting the engine or the electronics. For 1k you can get yourself a reasonable stroker kit and if you have a mechanic mate your off on your way. Just get a cheap 5 litre and stroke and rebuilt it, no point in getting a new engine if your building a new one anyway and all the old stuff will just be junk.

    Cheers guys!! would a 5L from a vt fit in? Cause I'm not to sure how I'd go finding a vn-vp 5L that's in good running order.

    Yes. The engines haven't changed, externally at least, between VN and VT but you would have to run the VT engine management to be legal. You might get away with running it with the VN management but you are not meant to.

    There are some differences in the distributor and the injectors too that will affect an attempt at plug and play with an engine from a VT in a VN.

    I think you'll find you're quite a bit off the mark here mate, for 1k you will get absolute rubbish. To build a stroker you'll want in excess of minimum 4-5k or you're wasting your time.

    If you need a new engine and don't have that sort of cash laying around i'd suggest getting the 304 rebuilt, maybe throw a larger cam in and give the heads a bit of a tickle if you're so inclined.

    My brother is in the industry so he gets the parts at cost or from people who didnt end up going through on their project. If you have people who can help who know what they are doing then the price can be reduced again. Either way its still cheaper than putting in a LS1. Its all about shopping around and finding the best deal whether it be on Ebay, here on just commodores or in the good old trading post. People buy these things for projects only to realise they dont have the time, so you can pick them up real cheap if your patient.

    Yea I'm think about just buying a 304 and rebuilding it! But at the moment I just wanna get a engine in it and some plates on it and the yellow sticker off the window! Then I'll look at stroker kits and the other little things I'd like to do to the 5L monster. But yes cams will get done during the rebuild and I'm thinking twin throttle bodys aswell or a harrop single plane inlet manifold but I'm not sure how the cops will like the twin throttle body or the manifold (depending on what way I go) when I go to get plates for it

    You can buy a crate LS1 for like $5500 brand spanking.

    A grand for a good stroker setup..... Your dreaming, I'm in the industry and I can tell you, you would get junk... Probably Procomp... Even if you got a backdoor deal or got it at lowest price, for a grand it would be shit.
    Your looking at excess of $4k for a tough 383/355ci.
    But with less effort an LS1 will still make more power.

    Oh yeah, of course.

    I also have contacts for parts and assembly and for sure, it does make it easier on the pocket however it is still not a cheap exercise and as I say, will cost in excess of 4-5k minimum.

    I was just assuming that the OP doesn't have any such contacts though.

    I got plenty of contacts but I would like to do most of the work myself!
    But with a ls1 crate motor wouldn't I have to change all my k-frames, etc? Plus then I have all the wiring and shit and that is just a head **** for me haha
    so wouldn't it be much easyer to use just a old 5L but have it completely rebuilt?

    And also any idea with the manifold n throttle bodys? What would be better way to go? And less of a target for cops.
    And with a harrop single plane inlet manifold would I have to get rid of the injectors and go carby.
    But I am thinking twin throttle bodys are sounding the way to go!

    Yes, you would need to make modifications as mentioned earlier to fit an LS series engine.

    Yes it would be easier to do that.

    It will make no difference to the authorities, an aftermarket manifold is an aftermarket manifold! Best option is to track down a Starr manifold and use that, they flow quite well and look standard.

    The manifolds you speak of can be made to suit both carby and EFI setups. All they do is drill out injector ports if the manifold is to be used with EFI.

    There's little point forking out for a decent twin throttle manifold unless you're getting serious about the setup. Bear in mind, if undertaking extensive engine work you'll also need to upgrade peripheral components such as fuel system, trans, diff etc... Also factor in tuning costs on top of everything else. Just make sure you can afford all the additional work as what starts out as simply 'building a stroker' will usually get very expensive, very quick.

    Yea I know! I built a vn s pack up. One part turned into another an so on! And wasn't smart when I was a apprentice. Then I ended up crashing it and blowing the gearbox!

    So with the ss I'm thinking about twin throttle body, cams etc, exhaust, stage 2 shift kit and 4:11 ratio in the diff. And leaving it at that, then redo the interior, rims and paint then look at a supercharger (probably just a side mounted one) and maybe stroking it at the same time.

    It should be good fun once it's back on the road!

    If anyone knows of a better idea for the ss please let me know!
