Is it the engine pictured below? If so I would do a "cut and shut" operation to lower the plenum. I've seen it done on an injected
Pinto engine. The DOHC can't be much different.
Bike carbs might be an alternative I suppose. You might contact Bogg Bros and enquire.

Understand now.
As said bike carbs are one way to go, the other being Weber or Dellorto.
Bike carbs are a fair bit cheaper to buy but you'll need a manifold to go with them, around £300 from Bogg Brothers (that's what I
paid).
If you bide your time on eBay you could maybe pick up a pair of second hand Dellorto 40s and a manifold for £250, I did when I had the Crossflow

If I was at the engine install stage I would seriously consider a diffrent engine as the DOHC engine is a heavy unit and no much in the way of tuning
a 2 litre pinto would give a bigger power output
Life is like a bowl of fruit, funny how all the weird looking ones are left alone

And a Zetec can be picked up for as low as £50 although you still have to spend the money on the carbs etc. you do get a better engine

Yep.
There is nothing wrong with the twink IF you you can make all the bits to install it your self. If you want of the shelf parts get a zetec you wont be
disapointed.

There is a carb variant of the twin cam, uses an odd ford/weber carb, I had one and was going to use it in an MGB, but to be honest, including buying
a zetec it was cheaper than doing anything useful with the twin cam.
Less than £200 will buy you a Zetec bike carb manifold from boggs, and as there is no coolant to worry about in the manifold making your own is dead
easy, just don't weld the runners on the wrong side of the manifold flange like I did......
