Can someone help me with identifying an engine please? I have a 72 Targa which came into the UK from South Africa. I was aware that it wasn't matching numbers when I bought it. Its running on Zeniths and pulls very well. I pulled the motor out to have the gearbox rebuilt so decided to put a clutch in it and fix the normal oil leaks. Anyway it is running alloy heads dated 1/70 - iron cylinders (no idea of age). I was told it was a 2.7 and is registered in the UK as a 2.7. There is no type number in the usual place. There are 2 engine numbers (both the same) - one on the fan tower and one at the rear next to the breather (was concerned that it was a 914 motor when I saw this) - number is 6025445. Understand the 6 is for number of cylinders ( check lol) and the 2 is for 1972. The type number 0 is confusing - any ideas?
