Thanks, Mel. Now we really should fit that muffler.

Calling all Jag Nuts -

Wouldn't a GM "Atlas 4.2L I-6 be a perfect replacement engine? IF NOT, WHY NOT?-Pray Tell.

@urah2525 I presume this is the Vortec 4200/LL8 found in various SUVs. Apart from the fact it's not a Jag engine and assuming it will fit under the bonnet, it seems like a decent idea. An aluminium straight 6 DOHC 16v redlining at 6000rpm and making 270 bhp in stock form sounds great. At least initially. However the specs and power output aren't that different from a Jag and the cost of engineering it into an E type and fitting it with a manual transmission are likely to be considerable.

@urah2525 Thinking more about your idea.. The expense of engineering a Vortec into an E type would not be cost effective, especially considering the loss of originality and the screams of sacrilege from the purists. It would not like dropping a short block V8 into a worn out XJ6 SIII (and there are many that say this latter practice is neither cheap or advisable). However if the objective is to build a hotrod, possibly with forced induction and a glassfibre bonnet it could be a fun approach...!

The problem with most of the V12s is that they are just too civilised (perhaps I mean quiet?!). The straight 6 is a very classic sound but opened up the 12's can sound glorious, especially when running Weber carbs.

Yes these cats really purr! A race level 4.2L motor will put out about 330bhp at the wheels. Very exotic tuning can produce more. 300 is about tops for a driveable fast road/rally/street car.

PS In the clip above the car was running without a muffler. The street version will have glass packs.

I have got a very good hint for you to keeping the nice old DOHC Engine in good shape with todays ultra dry eco fuels: Use 1:100 API TC two stroke oil / fuel mix as regular driving fuel, that keeps the old fuel-system gaskets, rubber parts, alloy parts etc... and cast iron metal surfaces of those vintage engines in excellent shape...and it also lubricates the valves and upper piston regions. Most Porsche vintage owners in Germany do so :) Also keeps carbs and tank clean and rustfree

Unfortunately the V12s are costly to run, especially if neglected. My mechanic has warned me off on several occasions when I've started to cast an eye on XJSs and the like. Your car will probably go just as well with a V8 and will be a lot cheaper to run. Good luck with the XJ6 (I had one for 5 years and loved it) and your E type: let me know when you put up the videos.

Sounds beastly, absolutely love classic British cars.

How much power can you squeeze out of a NA built up 4.2?

Thank you, scheese!
