    Default 355 build with Crane CC272 cam

    Just doing some research on a future engine build for my VK.
    Does anyone have any comments regarding this cam spec, in the notes it mentions that it s good "Group A" replacement stick.

    APPLICATION
    SERIES AND GRIND NUMBER.
    COMPONENTS
    CAM PART NO.
    LIFTERS PART NO.
    Deg. @ .050” Cam Lift Int. Exh.
    Deg Adv. Dur. Int. Exh.
    Deg. Lobe Sepa- ration
    Open/
    Close @ .050” Cam Lift Int./Exh.
    Lash Hot Int. Exh.
    Gross Lift Int./Exh. 3
    MECHANICAL - Good idle with lope, broad power band with good mid-range performance excellent replacement for GROUP A. Works best with 9.5:1 comp. and all normal street modifications. BASIC RPM 2800-6500
    CC272
    Chart C
    244681
    99250-16
    236 246
    272 282
    112
    8 48 57 9
    .026 .026
    .508 .527


    My engine is a VJ 304 (4.9l) from a VL, its a manual car with 3.23:1 gears (looking to swap out to 3.73 in the future) running 265/50/15 rear tyre. It's a weekend cruiser.
    My plans are to stroke to 355, 10:1 comp, pocket port heads, whilst continuing to run the #5955 HDT intake with a modified quadrajet & my HDT cold air tray...

    I'd make some changes to the cam... I would tighten up the lobe separation to 108 to get the valve events in a better position, if running the 5955 intake especially...

    She wont go much past 5500RPM pretty flat at 6000...

    I dont care what the cam card says the RPM range listed is for a 308 not a 355

    Agree ...I would not use that on a 355 ok with a 308

    and re LSA
    I always revert to this (from Crane)

    Leave the rear gear alone
    Put a small roller in it - 240 @ 050 .520” 106 c/l @304ci
    Strokers chew fuel and rubber
    On the street it’s always traction and wide rpm span
    Anyways - hope you enjoy your stroker

    its not going to RPM unless I put more cam so I might as well bring the TQ curve downwards with that gear, If its a cheapie build and heart is set on the 272.. Keeping the Crane 272 on 112LSA I would wind it forward 6° so the intake centre is on 106... Set intake lash to .020 and the exhaust to .018 or .016 instead of the mandated .026/.026 to see what it does...

    It would cruise OK...

    I tend to agree with Pauly (and no I’m not just jumping on the Pauly train) if you already have the 272 Crane solid or really want to use it.

    Noting your using early heads with a ‘pocket port’ and 955 inlet manifold these will hold back the airflow (read performance and ability to really rev) with that cam, but may just suit if it has a budget bottom end and you don’t really want to rev it. (??)

    If you were prepared to spend more money on the early heads (I’d just use VN’s and a different inlet) I’d go a small hydro roller for that ‘cruiser’ your after with some get up and go.
    Good luck and keep us posted on what you end up with.

    Pauly train, you can travel economy lol ... You know what, instead of this 355 I'd put a stock LS1 in this, maybe change the cam and springs and it'll be quicker ...

    Well, I used to get piled on for suggesting Ford engines in Holdens, but hes got his heart set on a 355 so... LS comment still gets frowned upon..

    Cam isnt big if you were to work out actual lobe area or area under the curve its dinky, it needs more cam lift if anything touch more duration. If you are choking it off with heads and intake then you can try to force it up with some stick...

    If this wasnt a manual, and it had a stock to 2200RPM stall, it would feel a little soft ..

    I know an LS would be a better (& potential cheaper) option, however as its a Group C tribute car I've built. I want to stay with the Holden engine, thanks for info & suggestions.

    I'm 6 months away from my engine build so I'll do a little more research, if any of you are interested in my build have a look. Thanks again.

    Nice one mate, thanks for YouTube link, it puts it into a bit more perspective on what you’re doing and trying to achieve.

    Leave it stock stroke and run with this, you might like it.
    Ensure a good fuel supply for the Qjet.
