We know that the Aston Martin V8 engine is development of the Jaguar 4·2 V8.
I read today, that the next Ford Mustang will be available with a 420bhp 5-litre V8. Years ago, the famous 4·7 Ford V8 I think, had a cast iron block, but their engine today is presumably more modern.
Is there any design connection, between the AM V8 and the current USA Ford V8?
The V8 is descended from a well known Jag developed V8, called the AJ-V8 http://en.m.wikipedia.org/wiki/Jaguar_AJ-V8_engine I don't think they have many (any?) parts in common, but the geometry is very similar.
The V12 is similarly descended (but even further removed from) from a pair of Ford Duratec V6s, end on. It's the same V6 used in the mondeo, I believe.

This comment about the V12 engine is wrong. It's one of those myths. Rather than quote this, have a look at the engineering background - who designed the engine and so on...The V12 is similarly descended (but even further removed from) from a pair of Ford Duratec V6s, end on.

Perhaps my original question was not worded very well.
It is kind of you all to reply, but you keep referring to the origins of the Aston Martin V8, and not mentioning the Ford Mustang engine. I already know about the AJ V8 and AM V8.
My interest was whether the present Ford Mustang V8 (which years ago used to be a cast iron block engine), now had any design connections or similarities, with the Jaguar AJ V8 and the subsequent development of that engine, the Aston Martin V8?
I presume that either the Mustang V8 is totally different, or maybe there is a connection to the V8 engines that we have in our cars.

Let us start by dispelling the belief still held by a few people that Jaguar just adapted a Ford designed V8 to create their new power unit. The truth is actually the reverse. Jaguar designed the engine in its entirety, it is manufactured in the UK, and a simplified variant is shipped over to the US where Lincoln install it in their LS model!
http://www.jagweb.com/aj6eng/v8_performance.phpThe Mustang V8 is a Ford Modular Engine, first incarnation with a cast iron SOHC.
The Aston V12 myth is one from Clarkson (although a prototype was build from two Duratec blocks).

The Aston V8 is similar to the Jag AJV8 in as much as it's a V8. The material used in the block is different, different heads, cams, valves, pistons, rods, sump et al.
One of my University lecturers designed the Jag engine, so believe when I say I have had hours of "tuition" based on the design of that one!
The Ford Mustang V8 5 litre is an all alloy quad cam 4 valve V8. It is derived from the one in the last gen Mustang the S197 but with many tweaks to improve power and efficiency.
Just wait till the SVO vehicles appear with the superchargers
There are some subtle differences to package parts for the RHD Mustang thus rendering it a "new" engine.
Believe me when I say the Mustang is going to be epic. it was benchmarked against the E92 M3 and the Porsche 991.
I have been lucky enough to be one of 2 Engineers in the UK responsible for the RHD vehicle, and have very much enjoyed the last 2 years. I want one in 2015.75
Hope that helps

The V12 has it roots founded by Porsche.
Ford then bought the design from them which went on to become the Duratec V6, along that line our V12's were spun off adopting some similarities but nothing exactly the same.
Ford developed the engine to a finished unit for a concept (indigo) until they scrapped the idea and offered the Engine over to AM for the V12 DB7's and so on.
So in simple terms we have a Porsche designed, Ford developed V12 in the DB7 Aston's tuned slightly by Cosworth and now built in Germany.
I'm sure at some stage Cosworth were left to one side and possibly prodrive had a further hand in some of the later models.

Hadn't heard the part about the Aston's block material being different from the Jag's. Can you elaborate? (Apologies to the OP for the topic tangent.)Speedraser said:

so if the material is different, only the block is a common cast part, the other components are custom....then theres not a lot of Ford bits left really?
so its a bit like saying every car shares some of the Ford model T design, as they have 4 wheels and steering wheel ?
Even more so as the blocks were derived from the same casting but are no longer common.so its a bit like saying every car shares some of the Ford model T design, as they have 4 wheels and steering wheel ?
I had thought that the 4.3 block was cast to the same specs as the Jag's, but was then machined differently, and I assumed that the material was the same. What are the materials used for the block in the Jag and in the Aston?
Mikey, I've thought that the 4.7 block is not cast to the same specs as the Jag's block -- is that correct?
I did know the crank material (as well as the stroke, of course) was different, as well as basically everything else.
