If you decide to part out the one engine I would reckon these parts will be of use to a Jag-Lover:
NLA = No Longer Available
Prices taken from SNG Barratt 04FEB22
Distributor (as you already said) (British Vacuum Unit in NH will rebuild (all new bushings, bearing, et al), new cap, and install vacuum advance for ~$250
Ignition Amplifier
Ballast Resistor Pack
Coil
Air Filter Housings and Trumpets - NLA (can be pricey – I’ve seen on eBay for couple hundred $$)
4x Intake Manifolds
4x Induction Housings (NLA) or
2x carbs on a pair of Induction Housings
4x carbs or
2x carbs still connected to a pair of intake manifolds
Any combination of the above
fuel anti-return valve (just forward of driver’s side pair of carbs) $34 new
All the steel lines (fuel, air balance, small, thick, etc) bridging over the block between the carbs and intakes - many/several are NLA
Throttle pedestal and 2x long and 2x short throttle linkage arms (NLA) with pivots
2x steel T-fitting nestled between each pair of carbs. The long arm of the tee is barbed; the 2 short arms are smooth. $44 new
2x front thermostat housings
2x rear water rail housings (NLA) or not available on-line
A/C Compressor
A/C Compressor mounts
A/C Belt Idler
Alternator (new and refurbished - $350-500; still need a core though)
Voltage Regulator
The 5-6 relays (which may not be present on block; may have stayed with car)
Oil Pan (if engine is out of E-Type, nice return ($$), if for XJS, plenty around)
Oil Pan bolts
Oil Cooler (NLA but aftermarket) and 2x elbows ($135 for after market) (flows the coolant thru itself thereby reducing oil temp by 20°C while raising coolant temp by 2°C) NLA but after market available
Oil Cleaner Assy (holds oil filter) aftermarket available
Oil Feed Pipe - also takes oil pressure sender; if the feed for the block is behind LR exhaust manifold, not so nice, if the feed for the block is below and behind the throttle pedestal, if have something NLA
Dip Stick and housing tube
Water Pump (rebuild kits available but need core)
Water Pump Bolts
