A new member and owner of an xk 140 FHC. Unfortunately it has a Chevy V8 and auto transmission in it currently. I’m going back to Jaguar…and looking for some advice. The heritage certificate shows it was an SE, not “C” type heads, and BW auto transmission originally. I got it at a good price, have a decent budget to spend, body seems ok, interior and paint that I can live with. I really don’t want to end up with more in the car than it’s worth. My goal is a “driver” rather than a prize winner.
I’ve been doing some engine research and it seems like I have three options: 1) find a matching G series engine and box so I am as close to “matching numbers” as possible and rebuild them, 2) find a period 3.4 engine from a Mk1 or mk7, (maybe even an runner?) and appropriate 140 box/5 speed, or 3) go big and drop a 3.8 in it and appropriate 140 box/5 speed.
Which would you chose - 1, 2, or 3? It will never be a matching numbers car, so worth going for a “G”?
If I go for a non-G engine…Oil Sumps, pumps and filters seem to be the problem from posts here and conversations. 140/150 sumps are scarce as everyone knew but me, and no economic reason to sell it separately from an engine any more. Mix and match on the sumps and you may need a new oil pump/piping as well. So… which engines would “drop right in” to a 140 as I don’t have the parts to move across to adapt it? If not drop right in, can you modify other sumps to fit… e.g. if I went with a MK1 engine (which has the right style oil filter and mechanical tach) I’ve been told you can cut off the sump “wing” on the exhaust side, close the resulting hole, and the exhausts will fit.
I recognise a question AND a follow up are pretty cheeky for a first post but hoping to learn from other’s battle scars.
Big shout out to Rob Caveney in Hawaii who helped me get an honest view of what I was buying. Suspect he will be reading this - he’s posted in the past. Quite a gentleman.
