Hi Chuck
I have not gotten a completion date from Fran yet but it should be fairly soon. I am not a mechanic but I have a pretty good knowledge of the Jag V12. I have been a big Jaguar fan for 30 years and currently have 3 Jaguar V12 cars. Of course I also have a V12 sitting in the garage but doesn't eveyone?
The engine headed for the XJ13 was built by a well known V12 guy and is overkill for a street car but I am trying to do it right. It is a 6.8 liter/416 cid (stroked and overbored) 13:1 comp with some extensive head work but designed to run on pump gas. It is waiting for a set of intakes and 6 TMW twin throttle bodies. When they come in I plan to send the engine up to Fran to set in the car so he can make me a set of headers that will fit the car properly. Plan is to use a G50 transaxel. Fran has done some replica wheels (not cheap but essential I think).
BTW a few things I would suggest if you are considering building one. First is go fuel injection all the way. Early V12's used 4 stromberg carbs and this was a compromise as Jag planned FI but could not get the system reliable in 1971. After 75 all V12's were FI and you can get a Jag V12 FI motor with ECU etc very cheap probably less than one with carbs. 6 Webers are an option but expensive and if going that route might as well use the FI twin trottle bodies ie TMW. The best bang for the buck is a 5.3 liter HE FI V12. About 300 HP (350 with rebuild) and plenty of torque and and will easily rev to 7000 rpm (8000 rpm is probably even safe for short bursts)
The cabin has more room than the original which had cooling pipes in the cabin but the car is very low at 39" to top of windscreen. Headroom is obviously unlimited but if you are over 5'10" your head will probably extend above the windshield. (I am luckily short 5'7")
Look for more info when I can get around to my build blog.
