yeah it was me that was on about the 4.4lt..
i was to do it to my turbo build,,.,in order to reduce the lag, ive opted to make the bitch rev instead
the process involoves offset grinding the crank, with some 6.5 inch rods, now thats all well and good, but with out sleaving the block and adding a spacer,,, no pistons are short enuf, even customs will not do, as the gudgen pin will be too high.
so, i have gone the otherway.
6.27 inch rods, with 60 thou over pistons. then off set grinding the crank to reduce its thow, and installing short stack pistons.
this way the rpm limit is bumped up to 7k easy
and more rpm= more power
