I have decided to stick with the little 4, we simply need to add an old carby of a holden grey motor, a 2 inch sports exhaust and apparently the bees knees is the result, is the a loca canberran with an old 2.25 from a series 3 thats unwanted I could work on and try for more power with a cam and some old racing engine trix that dont involve money, some head and valve work and apparently the power can be doubled, next question whos got a set of extractors to suit a 2.25 are they available of the shelf by genie or perry or pacemaker headers
