    Welcome,

    427ci in a Dax, nice... What kind of 427? stroked Ford/Chevy or a big block sideoiler?

    I've got a Dax427 so I'm biased! Good quality car, but then they all are nowadays, Dedion variant provides excellent handling. Search through the posts, particulalry the "newbies" forum and you'll see the question "which kit should I build" has been asked many times.

    If possible head along to a club meet so you can try a few out for size. Best of luck with the build

    i have no idea which engine as yet as i don't know what is out there and which one would be best suited. I am fully open to all the guidance i can get at the minute as i am such a newbie to this. I have seen an LS7 which looks quite neat but then there may be many other better choices?

    ok then if you can post up some ideas of what you're looking to achieve, ie authentic or bling mobile!, road only, some track days etc plus if you can indicate a rought budget you have in mind, then the crowd here would be able to offer usfeul advice

    Hi Pilot chap (are you a pilot?)

    Welcome to the forum. The two cars you have picked out are both great cars. I reckon the GD has the edge on the chassis design but The Dax has a very nicely done De-Dion suspension design. Also check out the available cockpit room as the GD transmission tunnel isn't exactly small.

    If you really want a 427 then you could go for a special small block motor based around an alumnium Dart block or go bigger and fit a 454 big block Chevy or even the GM 502 motor. The Dax demonstrator has a 502 so be sure to go have a look.

    Don't under estimate the smaller motors though. A 350 or 383 Chevy with the right gear on it can give you 450 horse power. That should be enough to scare you for a while.

    Craig.

    Built a Dax once, Long time ago, painted it blue, original huh...?

    If you really want the magical 427 number then (washes mouth out ) perhaps it ought to be a Ford?

    Yeah alright, Forgot that option!

    To be honest though, is it really an option? I thought the genuine 427CI motors were damn expensive to find because all the Americans try to fit them in their Cobra look a likes.
    Isn't there a cheaper Ford option that looks near enough the same from the outside 460?

    I think it's the 390FE that can be made to look externally like the 427. Some folk even tap the core plug holes in the block for threaed freeze plugs in their quest for a 'look a likey'.

    Understeer is hitting the wall with the front of your car, oversteer is hitting the wall with the rear.

    Its distasteful to think of, thats why...lights blue touch paper

    I was thinking more of a stroked ford small block, isn't there a combo that reaches 427ci?
