Re: v8 capri
73GSCOUPE, the Capri is a good candidate for a v8. I have a 1970 GT capri, and am putting a Lexus 4.0L Quad Cam in it. One thing you will need to check is with your local registry authority. A lot of the rules have just changed as to what engine you can put in what car. If you were in NSW, you can not put a 351 in a capri, too big in the weight Vs Capicity equation. Check your local rules first to see what you can do.
Once you have the crap sorted out, the fun begins.
A 351 clevo will fit in a capri. It will go in without any modifications to engine bay, but will sit forward of the cross member a little. You will have to get creative with engine mounts. A windsor is a much easier conversion. Castlemaine rod shop do a conversion kit for the windsor into a capri. Has new chassis rails, rear tie bar, gearbox cross member, tail shaft loop, cross member strengthning kit, stub axle adapter kit for bigger front discs. You choose between falcon or P76. I get the p76 kit, much easier to fit, and sits the front wheels furthur in board. Much nicer looking job. Kit also includes adapters to use HQ girlock callipers, and engine mounts to bold a windsor straight in.
As for the trans tunnel, it will depend on what capri you get. Some of the early mark 1's had there trans tunnels heat shrunk to fit around the trans better. This was more the case in the manuals than the autos, as it is a much smaller box. In most cases a ford C series trans will fit quite nicely in the trans tunnel. The only problem you will have is that you will need to kit the engine and gearbox as one for your final install, as the top trans bolts are almost impossible to get too once the engine is in the engine bay. If you want to modify your heater box location, and open up the trans tunnewl a little, this will give you more clearance around the back of the engine for getting the trans in and out.
With the brakes, the fronts are sorted out with the Rod shop rail kit. Rear brakes are you call, either disc or Drum. I am running a hilux diff in my capri, and the std drums on it, and it will pass for rego in NSW. You will need to upgrade your master cylinder, and probably add a remote vacuum booster, similar to what minis, XT falcons, and Early valiants run. Most common is a PBR VH44. You can find them in australia in the net, just need to hunt around a little.
Thats about it for driveline/brakes. Lots of other little things you can do thou. Mini tubs, move rear suspension inboard. With std spring location, you will not get much bigger that a 225 tyre under the back of the car, without largely flaring the guards, or adding A9X flares or similar.
If you have any more questions, please feel free to ask, i am not an expert by any means, but have been playing with capris for some years now, and have had most troubles with my own conversion.
Good luck with the project.
