I am rebuilding a 1043cc mk3 boulevard , have in my possesion a 1.3 head thats been ported and flowed and a kei hins carb of a hornet 600 . my questin is will a gt cam fit , what would be best ? and also who can build be inlet manifold.

Is it just the one carb you've got? You'll want 4 on their original linkages, which might need a bit of extension. You'll have to make a throttle cable and choke cable. Yes, the GT cam will fit and would probably be the best one for the job. If you're car is a K reg or later you won't be able to run bike carbs legally unless you can get the engine to run really, really clean.

Harrogate eh!

Give me a wave next time you see a Gambia Red mk1 Golf. I've got a couple of sets of Keihins to play with. Get in touch.
