Can anyone provide please a comparison of photographs that show and can quickly identify the following 4.2 litre engines for easy recogition?
7E for the e Type Series 1
7F for the 420
7L for the XJ6
Also was there a visual difference in the manual Moss Gearbox and Overdrive units on these three different engine installations?
I appreciate that there are internal and perhaps out of sight differences, but how do you spot what restoration work is correct at car shows?
