Hello, I have been takeing my xj12 engine apart and now I need to get new studs for the thing and I dont know which ones to get from Terry Jag Terrys Jaguar Parts?
Also I pretty sure its a 77 xj12 but here is the engine number if anyone know how to decode that to tell me what it came out of that would be super awsome! 7P27555
Oh and one more thing this is my first engine that I am rebuilding so any tips on what to do would be very appreciated.

 

My Jag engine identifier tells me its a 5.3 litre XJS engine but doesn't specify a year.

 

Thank you I will take a look into XJS now.

 

Hi Kenshin

They are basically the same. Its the V12s birthday this year as it came out in 1971 with what is referred to as a pre HE version.
The head was redesigned to be more efficient and these became known as HE motors. The only diference between all of the newer ones before it was changed to a 6ltr is the fuel and engine management systems so major parts should be the same.
Regards
