looks the same as my 420G

Well similar, except your has a short stud block and if you look on this one you see the slots between the cylinders? This was only from factory on the very last ones made in the mid 80's because the block casting tools were all worn out and the truth is the late blocks not only cracked between cylinders but would shift too, leading to constantly blown head gaskets. However, it is also common for all mid 70's on blocks to crack between the siamesed bores, often without blowing head gaskets for many miles. So some diligent shops when they do head gasket changes also slotted the blocks as a precaution. Ideally you need a more specialised gasket to keep a good seal because i guarantee you, your 420g engine will go many, many more miles between head gaskets than this one will.

Best combination in my experience to build the best 4.2 engine was an early 4.2 block and a series 3 injected head, even if you still keep carbs. But be careful the 4.2 is not too early as they have different oilways and you will find you are leaking oil out the back left of the motor if they do not match on both sides of the head gasket. As for carbs, 2 x 2" SU hd8's are unbeatable on an xj6. If you cant get those then use early 2" hs8's. But throttle bodies is the ultimate way to go.

@ lovely, thanks for the info.

@@kennethtalbott2233 I am not a professional builder, but I have lost count of how many of these I have had and done over the years, and everything I have told you here works, and works well, because I have done it many times. Hope it helps in some way. I have many, many parts for these cars too if you get stuck

Yes in Tours

@JoshTurner37 did live and work out there before Brexit happened now it's so much more difficult. Really looking forward to seeing the end result of the oh la la jaguar. I also feel in love with the stunning XJC from restomoods. Just thinking the XJC is such a stunning looking Jag did see the restoration of Harry's garage with his an also the one called Emma that was sold last year buy the chap who did Harry's. Really well made video of what you're doing thank you for sharing this project

Hi Stephen, I have been scoping internet for years looking for Restomod Jaguars, I can't remember exactly where I found yours but I must salute you sir, you have made a beautiful and inspiring car !
