Does anyone know the best way to cut the plenum chamber as per the build manual.

What's a vellum chamber?

Isn't vellum a type of writing matieral, made from animal skin if memory serves me right.

Don't you mean plenum chamber?

only reading what it says in the build manual. plenum sounds more like it.

Does anybody have any suggestions or recommend someone to do it for me?

remove it and use carbs

If you do a search, there have been a couple of people who have mod'ed them and posted pics in archive as well.

Blowed if I can remember names though, sorry. personally I don't think there is a lot wrong with the injection set up (apart from rechipping to plod standard. They were all they had till henry started using bigger engines and using the cosworth.)

The guy who won Locost of the year s
at Newark had a beautifully modded plenum, cut it up, shortened, turned upside down and re welded - very neat. Even went to the trouble of cutting off the 'EFI' plate and re welding the right way up!
Don't think he comes on here though. I may have a few pics, I'll have a look tonight.
