    A 253 doesn't really go much better than a 202, and fuel economy isn't much different either.

    I'd try and find a good efi 202 long motor, replace the bearings and rings, have the head shaved to get it to somewhere near 10-1 static compression, and run a crow 35604 cam. Run a 34adm weber off a falcon and the stock carby intake manifold (verajet).

    I had that cam in my 202 and it was good fun to drive with the aussie 3 speed. I'd use it again for sure if I were to put another one together for a cruiser. I really like the sound of a cammed 202, and they can go really well if you do everything right.

    I've got a 34ADM if you want to stay with the 202.

    Just hook the pollution gear up and it'll be fine. It's not legal for you to drive a modified car anyway and you're set on modifying it, so why would having the pollution gear removed bother you?

    You need to do your own research and figure out which engine you want to use. There are thousands of threads on the web to help you decide. Gmhtorana forums, AV8 and JC are the main ones you should be searching to find the info you need.

    The 34ADM if from a XF Falcon, produced later the the WB and has all the emissions ports you need to be legal from that standpoint, P plates is another story. Basically follow Eyys advice, he's done this before.

    Well you have never seen a worked one then...

    The 186 from my old torana replaced a 308 in a boat and it was just as quick.

    The same work can be done to a 202, in fact the basis of the 186 I had was the 202 crank.

    i saw a 179 with a 202 crank and some comp 11-1 i think it was making near 300 hp

    can i get that from a 202 if i put like 186 heads in it with a big cam?

    No.

    Why does a hp figure matter to you so much?

    Why not go old school....186 with a Ford 221 crank.....

    I am in the process of piecing together one.....it's going to be fitted with a black 3.3 head, the injection manifold will be the feeder for the sc 14 supercharger.....Not sure whether I'll fit a 465 or 600 holley....

    Gearbox is a supra 5 speed

    if only i could have a supercharger on p's :)

    im just thinking either a 253 or a 202 with some mods with supra box on both either one sounds intersting

    some nice cam, head, extractors, and some big ports

    Wow , if you go 202 , there are like so many options ..
    Cams , heads , pistons , Short blocks , long blocks , how about fuel injection ?
    There is no reason you cant build a seriously strong 202 for far less money than a V8 .
    Think GTR XU1 ..
    A nice strong bottom end , good pistons + rings , yella terra head + rollers , and a decent cam ..
    Then for intake , Single carb ? Dual carbs , triple carbs , fuel injection .

    How about a BLACK 202 ? (?) Dont know if anyone did anything good with the black ..

    The blocks are all essentially the same with the exception of rear main seal types and a few extra mounting bosses used to mount ancillaries. The major difference between the red and blue block is the position of the coolant passages which is easy to modify to enable the use of the later 12 port head as found on blue and black engines.

    The problem with the old sixes, is that parts are much more expensive than their v8 counterparts and the variety and availability of parts isn't even in the same league. The point is, if you spent the same amount on a 308 as you did on a 202, the little six wouldn't stand a chance.

    A hot 202 is $4K+ depending on how hot you want it. But in a big H series holden I'd go a V8 any day.

    Hot sixes are nothing new but I wouldn't bother when you're putting it in a WB.

    Go a 253 until you can go bigger. Won't be that quick but will sound good and it's an easy/cheap conversion.

    Leave the hot sixes to the Toranas.

    Hmmm , a 12Port is said to be good to 240BHP with very good torque ..
    And the 9 port is good to 400+ HP ( more up top )

    And not all blocks are the same : Apparently the RED BLOCK Boys have their favorites to build on ..
    12 PORT , usually built on Blue or black blocks ..
    Hmmm , a fuel injected 240BHP BLACK 12 PORT ..

    Nah mate you've been misled. For a 9 port to flow enough to make half decent power youd need to spend a couple of grand on head work.

    Only reason to stick with a red block would be hq racing regulations.
