A friend has asked if the J60 engine would be useful as a spare for his civilian Mk2 Jag. Can someone kindly give a basic idea of what would be needed to use the J60 in a normal car instead of the civilian 4.2L engine. Obviously the carb and all other ancillaries are irrelevant.
- Is the bore stroke different (he thinks a J60 is 4.5L)?
- What is the J60 stud pattern - he thinks there are 2 versions of Jag engine with the later one having "long" cyl head studs that penetrate the water jacket to get to the block and obviously therefore have corrosion issues?
- Does the detuning of the J60 for military purposes mean the pistions etc are all different so that the only really useable bits left from the J60 would be the head and the block itself?
