After fitting and removing the engine numerous times without the alternator fitted I was able to finalise and confirm it would fit then started working out the belt.
I stole an idea of someone else’s engine conversion and used a Range Rover P38 adjustable air con pulley as a tensioner which required a spacer machining to enable it to bolt thru a M8 hole on the front engine cover.
I measured the belt length using a flat tape measure at around 1080 mm then made a quessimate to the required belt length available which ended up as a 6PK1076 belt.
I fitted the engine again !
It’s a bit of a faff trying to fit the alternator, I had to fit the top bracket to the engine then fit the alternator then install the bottom bracket whilst lifting the engine slightly to get the bottom bolt over the chassis rail but it all went in.
Although it all fitted ok I wasn’t happy with the clearance between the pulley and the upright chassis rail, thinking that any engine movement might cause it to clash, so out with the engine again and I “scolloped” out the chassis rail slightly (about 10mm) which now give lots of clearance.[url]

After a lot of procrastination finally decided on method of mounting the inlet manifold.
First idea was to get an adapters machined out of billets of aluminium so I drew a sketch of the Jag lower inlet and the Ford Mondeo/Cougar 2.5 ltr manifold and was going to get it drawn in cad but that’s as far as I got !
Then it was suggested that it would be possible to get it 3D printed in high temp plastic and managed to get a base drawing off someone already doing the same conversion. My problem with this method was it was going to be printed by a friend of a friend remotely so I would have no control over the process .
Eventually decided to just do it.
I needed to adapt from Jag to Ford so what I did was cut 20mm slice from the bottom of the original Jag S type manifold and bought the cheapest Mondeo/Cougar ST200 V6 upper svt intake manifold and took a 30mm slice off the top.The Jag lower was bolted to a Mondeo lower intake manifold which is the same pattern as the Jag and the upper Ford intake was bolted to the air intake manifold.These were aligned as best I could the welded together( this took ages as I cannot Tig weld ! )
The final result is ok and I am happy enough with them and think it will work ok.

Decided it was time to try to fit the bonnet.
My project car came with the bonnet already removed so didn’t know how well it fitted originally.
After numerous disappointing attempts to fit and align the bonnet correctly it turns out they don’t always fit that well!
Decided to bin the original hinges and started looking round at other people’s solutions of getting the bonnet to open a little bit wider.
Bob Honnor was kind enough to send me all his amazing comprehensive drawings of his design which I decided to use but adapted to make it easier for me to make with my limited fabrication/welding skills.
I made the chassis part of the hinge out of stainless steel box section using dimensions gleaned from Bob’s drawing.
I had to replace the rotten plywood bonnet webs which gave me more material around the new pivot point.
The bonnet part of the hinge is BMW Mini top mounts with the studs punched out.
These fit together with 2 M14 bolts, I also added gas struts from my donor S type as I already had them.
I also decided to trim the inside lower edge of the bonnet to allow more opening angle, the whole bonnet needs a respray eventually.

The webs need a bit of trimming and finishing and please ignore the bad welding !
