Step 1 is to fit a 350 crate engine and satisfy the WA licensing department.
I carefully wrote out my application paperwork and sat back and waited for five weeks for a reply.
Last week my application returned with a long list of "Approved" 350 chev, TH350, 9", 290mm hoppers kit, suspension, extractors
and then a big "rejected" for 15" wheels !

So who knows the legalities of running 15's in WA ?
Looks like I will have to run HQ front rotors and 14's to get it over the pits....
