Welcome Jono -
And owing a GT40 is fortunately not a requirement for membership...I don't either...
Good luck with the Cortina - sounds like it could really be a 'savage' beast with a 302 in it and hey it can't go wrong really, as its already got a FORD badge and hopefully - 8 Cylinders!!
Use the search function for answers to most questions you may have and the very knowledgeable membership will I'm sure help where possible with the rest...
