I have just put another modified block with new slipper pistons valves guides springs,
fitted a pigsty race cam
and new shell bearings under the whatmough head, also a lighter flywheel clutch assy.
my tickover is a tad lumpy as expected, car pulls really well and will hit over 5000rpm on light throttle I just need to run it in a bit more. before I really thrash it.
engine sounds sweet and will pull from 2000 RPM,
