The engine is a rebuild from a wrecked car, no idea what year the car was either. I'd like to identify what year the engine is, the code is 7L49387

 

Looking at page 4, maybe a S1 XJ6?

 

I found a an early intake manifold C30375. Will it fit my 7L series engine with Stromberg 175-CD2 carbs?

 

It will definitely fit the engine. It needs a thermostat housing, and one of the long studs is either broken or missing. They do frequently break and corrode, so check if there is a stub left at the bottom of the hole.

I'm not an expert of Strombergs, I believe they were 1.75" bores. There were 2 carb manifolds made for 1.75" carbs and 2" carbs, I'm not sure if the bolt pattern is identical or not. It is for SU carbs, I don't know for Stromberg. I generally prefer SU's, as they are much more adjustable.

 

I've got a 1959 3.8 bell housing bolted to a 4.2 S2. The 3.8 starter is bad, is it possible to use a later style starter? The 3.8 bell housing has a long narrow starter hump, it's different than the later model bell housings.

 

I am assuming you have Manual Transmission ( some automatics have 132 tooth Flexplate ring gear)
You can use a modern aftermarket gear reduction starter, they are available from all the usual sources. There are two models, one fits 3.8 bellhousings with a 104 tooth flywheel and the other a 4.2 bellhousings with a 133 tooth flywheel. If you have a 4.2 flywheel, you can get a 104 ring gear for under $100 and have machine shop remove old ring gear (133) and install new one to match bellhousing and starter.
Bellhousing, flywheel and starter must all be from same series. They as a set, will bolt up to a 3.8 or a 4.2 engine.
If you have Auto Trans, you will have another two geared starter options, again Bellhousing, Flexplate and Starter must be from same series.

Also note that the release bearing must match the clutch. 3.8 and 4.2 are different. A 3.8 was a 10" spring clutch and 4.2 was a 9" diaphragm clutch. Some flywheels are dual drilled, some are not.

 

Is there a basic 3-bolt thermostat housing, just a hose fitting, that would fit this manifold? Or is it a box shaped housing with a fill cap and hose fittings?

 

I purchased a 1959 3.8 with a Moss 4 speed and a 4.2 S2. I plan on installing one in a hand built car I designed and fabricated.

 

It's two seperate pieces. There is a spacer that contains the thermostat and bypass port; and then the hose outlet. There have been a variety over the years depending on the car. You might contact David Bodger at everydayxj.com, he's a great source for various parts like that.

 

Here's two starters advertised as a 1952, looks like my starter, and the other one is a 1959. The 3rd image is the starter that was mounted to the 3.8. The 3.8 I purchased was attached to a Moss 4 speed in a 1959 MKI, it was stripped, rusted out and had been wrecked. There's no way of telling if they were numbers matching to the car I pulled them from. My flywheel is a 104 tooth. Does it matter which style starter I use?


1952 Starter


1959 Starter


Starter that came with 3.8

 

It looks like the 59 is what Moss is showing, N/A with them now, but $650 core charge for rebuilt ??

With respect to your project, which looks great, the rebuilding of a 4.2 engine for a one off classic, I would not use that manifold as a starting point. In my opinion that manifold is one of Jaguar's worst designs. You are giving up 20-25 HP to build engine around a "smog" manifold. The 420G or Mark 10 tri-carb manifold or XKE tri-carb manifold are immanently better as a starting point.https://mossmotors.com/jes-9249-cool...stem-mk-x-420g

Used 420G manifolds are half the price of E-type manifolds, both of which flow better and parts are still available.

See my XKE upgrade thread for back ground.
