    Default Advice needed - 350 or 383 into an HJ Kingswood

    Hi all, long time prowler on here but have just recently joined up as I have purchased a 76 HJ Kingswood. Has bench seats front and rear, 202 and 3 on the tree, with a tired whining banjo.

    Anyway I have been reading through some posts here regarding engine transplants etc, and was hoping there would be sort of a 'how to guide for morons' like myself, regarding putting in a 350 or 383 followed by a t350 and maybe a salisbury diff? However I can't seem to find a detailed thread with photos.

    I'm after a little guidance really and opinions on what a good combo would be? First thoughts were as above. I have swapped a like for like engine before but never replaced a different engine and drive train. Also interested in talking to people regarding keeping the column shift using an adapter to the t350, apparently it can be done? Im not after a race car, just want it to have a bit of pep if needed and sound nice. Would also like to keep it all under the bonnet if possible, not sure if this is possible with a 383? Would probably keep it carburetted for simplicity and sound.

    Sorry a lot of questions I know but I'd prefer to consult with the professionals on here before just going for it!!

    Any help with this highly appreciated.

    hi
    Budget
    Time
    These will dictate almost every thing

    Max horse power will set the budget
    350-383 external balance or better internal balance ,forged rods /crank pistons or cast /Hyperutectic
    Easy way is a crate motor although some are Hexy
    OR
    buy bottom end assembled then buy a top end kit heads manifold etc

    Going above 425hp will need a 9inch and seriously beefed up tranny if u drive hard

    motor 5000 -10,000 $$ more fruit 15,000 to 20,000 for all out +++ skys the limit

    trans 1000-2500 average
    convertor 650

    Tail shaft cost ???

    9 inch 3200$ basic maybe open wheeler 28 spline
    3500 factory Lsd 28spline
    4000$ good Eaton Tru trac 31 spline
    5300$ all the friut 31 spline around 600hp capable
    approx. prices both use your brakes

    radiator heavy duty 1000$ included fans/shroud 1500$
    There are cheaper ,if u can get proof they work great ??

    Extractors 500--1500$
    Exhaust stainless or mild , you will need 2 resonators and 2 mufflers to keep the noise down and to stop the cabin drone 500-1000$


    You will need at least 24mm factory swaybar
    v8 springs front and rear
    lowered springs in a Hq etc gives a poor ride compared to other vehicles

    Beaware there are some nasty traders who take your money and take ages to source parts
    Also watch for over priced ripoff parts and avoid the Chinese parts internally in engine etc

    I was told
    wrong combustion chamber 1st time
    forgot to order cam

    2nd time
    wrong rocker studs

    This totalled 12mths WTF !!!!

    There is only a little wiring ,accelerator linkage or cable ,speedo cable ,trans mount and x member , carby, air cleaner, f/pump & reg ,distributor + plug leads ,Torque convertor cover plate , dipstick ,,starter motor , 90 amp altenator

    Thanks heaps for the info Swampy, I wont be chasing huge horsepower, something with a bit more toe than the 202

    Budget - was hoping for 15k
    Time - no time frame, will gather the parts over the next couple years
    Max HP - probably 400?

    Once I have all the fruit to put on, is there much to the actual swap? I guess thats more of what I'm after, im sure plenty of blokes on here have done it, hopefully I dont have to reinvent the wheel.

    Sounds like you got royally f%*ked around with yours. I may be lucky in this aspect with some contacts who can sort most of the parts for me ....

    383 all the way. By The time you get a stock crank machined, rods fitted to pistons etc. It will be cheaper to by a stroker kit. I paid $900 landed on my door from the states, a Eagle 383 kit. That included crank, rods, pistons, piston rings and bearings. Plus if you run stock cylinder heads you'll still achieve nice 383 torque.

    Hi
    290 hp crate motor 350cuin

    330hp crate motor 350cuin

    350 hp crate motor 350cuin

    The above are GM performance
    Either the 330-350 would be ideal
    Check em out there maybe higher hp available

    http://www.chevrolet.com/performance...l-block-ht-383
    SP383 Deluxe Small Block Stroker Crate Engine | Chevrolet Performance
    ZZ6 Base Small Block Crate Engine | Chevrolet Performance

    A 383 cu in biuld your own best going to engine builder for best package price

    Prefer internal balance over external but few more $

    cast crank ,I beam rods , Hypertectic pistons could buy this as a kit pre balanced to save money
    Inlet manifold Edelbrock perf RPM airgap "vortec style"

    optioned
    Cast iron vortec heads modified for high lift
    Buy after market vortecs
    Vortecs are available new and modified in USA for around 800$ but as with all things in OZ cost lotsa $$$

    Thanks again Swampy, some nice looking engines in there, the Powertrain options look like the go. Already matched up with the transmission. However I doubt they would be able to retroffited to the existing column shift? Which is really what im after, I want it to look reasonable stock standard from the outside and inside. I've heard there is a cable kit for the 3 speed column to fit the turbo 350? I'd like to explore that option and fit a 350 to that really?

    Please let me know if that is unrealistic!

    Also are there any threads on here showing a step by step or guide of installing a 350 chev? I can't seem to find any and I thought there would be a multitude.

    Well the build I did was for a 45 series Landcruiser. But physically the engine is exactly the same size as a stock 350. All the mods are internal. So you won’t have a problem with it being under the bonnet.

    350 or 383 will sit the same under the bonnet, it's mostly your choice of intake that will dictate whether is fits under or not. To clarify further a 383 is just a 350 with a longer stroke crankshaft, externally you can't tell the difference.

    A V8 swap in a H-series Holden is pretty straight forward, it's just a matter of collecting all the bits needed and it can all be bolted in.

    Hi
    Under bonnet clearance set by manifold height . Not talking stock replacement inlet manifolds.
    Performer rpm air gap on a 383 sounds right .
    Victor Jr is about 1/4 taller
    There are many reports on the Air gap vs victor jr. . Fairly typical is what the Vic gains in the top end [Hp] approx. say 10hp the Rpm wins back torque around 20ft.ibs of Tq./
    This comparison appears many times online.

    To run a deep breathing v8 you will need at least 2 1/2 or taller x 14 filter to flow the air u need .
    In order to fit these filters u will need at least a 1 1/4 drop base air cleaner assembly .
    depending on air filter u can get many DEEPER drop bases 1 1/2 1 3/4 2.0 inch

    Sorry for my ignorance but are a 350 and 383 identical in size externally? This is something I didn’t know

    Thanks again Swampy, certainly sounds like you’ve done this a few times before
