Je n'ai pas le temps de relire tout le post, et ça fera peut-être un doublon, mais David Robson (en Angleterre) vend sa Challenger 1970, et c'est une très bonne affaire. Il y a quelques modifications, et dans l'idéal il faut remplacer les culasses (les culasses en fonte ont été un peu trop fraisées à l'époque et ont percé, c'est réparable -ça peut se ressouder- mais de nos jours ce serait tellement plus simple de les remplacer par une paire de culasses alu préparées). La voiture est entièrement restaurée et a été finie l'année dernière.
Elle est à vendre 29 000 livres.Elle a été Best of show en 2009, second en 2010 (aux Mopar Euronats).
Si elle n'est pas vendue d'ici la fin de l'année, Dave va faire réparer ses culasses et le prix passera à 30 000 livres.
Il y a quelques pièces custom, mais on peut revenir à l'origine si l'on veut.
C'est un 440 d'origine (avec son bloc d'origine) passé en six-pack.
La voiture fait 11.92 secondes aux 400 mètres, elle a un overdrive Gear Vendors et un pont 4.30. La tenue de route est excellente grâce à des barres de torsion et des lames plus grosses qu'à l'origine. Le boîtier de direction est manuel.
