72mm Rover V8 plenum
Matts prototype with brass throttle:
The air inlet pipe on the end has a 3" OD, also i use aluminum for the throttle on all conversions.
I can machine out the "3.9" from the lid if you dont want it, as can be seen on this one.
MEZ 72mm Gems Plenum
OEM Plenum, which is 65mm and them same plenum bored out to 72mm by me.
Conversion notes:
The water jacket under the throttle (which prevents icing in certain climates) can be thin on some castings. On this plenum the wall thickness was 5mm, boring it out leaves 1.5mm.
All conversions have this entire area filled up with epoxy metal. This means the throttle heater will be rendered in-operable, which isn't an issue on Griff 500 engines as TVR themselves left it disconnected anyway.
72mm Plenum prices
If you supply your own plenum for conversion - cost is £105When I have them in stock, outright plenums are £150
Carriage in UK is about £15 and Europe is about £37 - you are welcome to collect/deliver.
Rover V8 serpentine 36-1 trigger wheel installation
To fit an EDIS 8 to a TVR Griffith 500, you need to fit a ford 36-1 trigger wheel (Part Number 1078767). The wheel is 2mm thick, so I machined about 1.5mm from the damper and a further .5mm from the pulley - the wheel is then clamped between the two.
The salot (dowel) pin, which was removed when turning the register on the damper is then used to secure the wheel in the desired location.
On the water pump, I ground the two protruding bosses down to provide a nice flat surface the simple VR sensor bracket.I also made an aluminium blanking plug for the distributor
Update: Thanks to Antony Pattison who identified the part number as F3DE-6C315-AB (F3DE-6C315-CB is also similar - google the part number)

ACT Products induction pipe
I finally shamed Matt into fitting an air filter on his car. Which meant I had to make a pipe to replace the AFM, which includes a boss for the GM air temp sensor.

Here's how to adapt a clarke 10 ton hydraulic press, to press the suspension bushes out. Then shot blasted and powder coated.
