has anyone here attempted mini tubs and shortened nine inch in their fc holden and who did the work for them? also anyone aware of kind of costs for this kind of mod?

hi my dad and myself are just begining our father son project of his fc holden restoration, and i was wondering does any1 know if u can still engineer this in victoria and i would like to go the chev small block preferably for power reasons, but is it easier to fit the holden 308 in or the chev? if any1 here has done the changeover could they please write me a list of items they had to do to get this to fit.

thankyou
