did some research today.
after 20mins on hold with vic roads ive realised there USELESS!
rang a engineer and asked him whats the go with 5k conversion.
he said
"he musnt be more than 20% powerfull than the standard motor"
4kc - 44kw
5kc - 61kw (according to wiki)
so WIN! he also said you must supply vic roads with a good excuse why you couldnt fit a standard motor. so ill just say "its a old car couldnt find any engines for it, so the next best think was a 5k out of a van witch was also a option for a corona's"
5k. super duper cam. (4000rpm-8000rpm or 3 - 7 powerband :D), HYDRAULIC LIFTERS, 11/12:1 comp ratio, weber. = win?
