you cant just bore it out to 4.5.. you need to have a different combination of rods and crank to stroke it aswell to get it to 4.5 ltr

i think 60 thou, is about as much as you would want to go without sleeving the block..
correct me if im wrong..

and from memory boring a 4.0l 60 thou takes it approx from 244 ci to 249 ci which i think is 4080 cc..
i did have a formula to work it out but i cant find it...
