The "tinware" is lightweight GRP. The throttle bodies have been bored to 42mm, fitted with new butterflies and rods

That is looking fabulous Nick.

What exchangers or headers have you bolted on there ?

What distributor will you be using.

Absolutely fabulous, the exact engine I would have in mine if I have the £££.

Hope to catch it (sound and visually) next year on a track somewhere.

Perhaps it will go to CLM 2010 ?

Not exactly. Although the engine is in the car, it will be some time before it gets fired up, then it will be straight onto Bob Watson's rolling road. Hoping for around 250 bhp.

Very nice work.

What will provide the sparks - twin Bosch CDI ? MSD ?

Is the space cam in the injection pump modified ?

The dizzy housing was glass beaded to dull the finish. There are twin MSD boxes in the passenger compartment. The space cam is standard at the moment, until we run the engine up we won't know if we need to change the it, but we are prepared for that.

Nick,

Did JB Racing also deliver the ignition wires and plug connectors which can be seen on this MFI engine?

Yes, the ignition wires and caps came from JB Racing, as did the various wire guides and clips.
