i have been pondering over this recently as il have a spare sc12 setup lying around after i turbo the gze..
i figure get a 3k block put a 4k head on to lower compression, enclose the carby in a box as to keep equal pressure outside the carby not just plumb it straight in,resulting in a blown up carby..
yeh thats my basic idea..but im a newbie to the k series engines so let me know if im wrong.
