Is there not an option to have the inlet manifold to bring carbs closer to engine and as a result lower ot change the angle of the carbs (manifold shave again) to provide more clearance
Or triple webbers
Triple Webber’s will require a new inlet manifold. A rather expensive option. Or triple webbers
Machining the existing manifold is possible but I think putting an angle on it to kick the carb over won’t help the damper inside it.
To remove the inlet manifold the engine needs to be out again so I can measure the part properly rather than taking a bit off and checking each time.
Just a pain really as I’ve seen a few XJ’s with triple su carbs but no mention of bonnet clearance issues.

Custom cut-down dashpot on the carb(s)? 
It's right up your (fabrication) street.
That’s the first thing I thought. Easy to do but I don’t think there is enough spare material to remove from the top and bottom of those dash pots. It's right up your (fabrication) street.
Engine sump needs more clearance off front subframe. So say 4mm minimum. Currently approx 2mm if that. Bonnet needs 5mm off carb to shut properly plus engine raise of at least 2mm. That’s 7mm off the carb to shut the bonnet and it will just kiss the inside of the bonnet still.
Still chipping away at this. Picture shows the machined slightly shorter carburettor dash pot on the right compared to original on the left.
I shortened it by 6mm. This removed the original thread to screw the damper in place. So that was re-cut also.
Picture below shows minimal clearance with the bonnet shut. With the reflection above there is a small gap between that and the actual carburettor. Another 2mm off should be perfect.
I also reduced the height of the coolant bleed screw which fits on the end of the carb manifold. Originally a regular radiator pressurised screw cap but that failed the bonnet. My version uses a stainless steel brake caliper bleed screw. Just push a pipe on and crack the bleed nipple until any air is purged. Then tighten when complete.
Picture above shows under bonnet reflection again with a good gap between reflection and actual part.
No need to spoil the bonnet with a cut-out/Louvre or bulge now. So very happy with that outcome.
Lovely work.Been a while for an update, but this will start moving again soon.
I’m always looking for better chrome parts or interesting parts to fit the xjc.
Recently I managed to buy a pair of smoked front indicator lenses. Being sold as single items on separate flea bay listings. I’ve never seen another set before. They wasn’t expensive either as they were sold as singles.
Will be an orange bulb behind them but that isn’t an issue. I think these will clean up the front perfectly so no huge orange lense to stare at.
Also ordered a new headliner biscuit today. That was expensive! But it’s new and will give a better finish once the new covering goes on (with no foam backing that eventually separates).

Silvered bulbs that flash orange would also work well to avoid the "burnt fried egg" lookI’m always looking for better chrome parts or interesting parts to fit the xjc.

that’s the plan 
Visited the xjc earlier today dropping off a customer seat as an excuse to see the ole girl.
She has been patient. The lads were making space to get her back into the workshop for paint prep.
I did notice how small she looks compared to the s-type I’ve been using recently. Especially sitting on 15” wheels. Still looking forward to driving her again though
