Well the spec is;
3.9 Ltr block
Much head work - large inlet valve with porting and combustion chamber work 3 angle seat and 10.8:1 compression
Rhoads lifters / followers
Isky 278° cam
Grp A trumpet set (45mm x38mm)
Bored out throttle body
Cut & shut inlet plenum to increase capacity
lightened, balanced bottom end etc
All controlled by an Emerald mappable ECU
Just need to sort the body out now having crashed it 4 weeks ago
Can anybody reccommend a good fibreglass bodyshop around Northampton?

I can't say how much the Emerald ECU is worth power wise as I've always run it ever since I started modifying the engine a couple of years ago. I would however reccommend the unit to anyone as it has been reliable, easy to use and very reasonably priced (£600). Quick run-down of the features;
3D spark & fuel maps
Hot programmable
Windows / excel compatible
No funny programmer etc required boggo laptop is perfectly fine 486/25 only.
Closed loop fuelling
Idle speed control
TPS or MAP sensor input
Water & air temp correction
Software /code changes via E-mail
It should be better than the standard ECU as the spark is mapped as opposed to the std clockwork / distributor.
Go and have a look for yourself.

For my 600 quid I got the
ECU
Wiring loom - requires splicing into car loom
Air & water temp Sensors
software
Comms lead
Ignition ampflier
Bear in mind that this system is not a plug in replacement, you have to do a fair bit of wiring and then to have to map it! At that point you'll believe the carburettor to be the finest piece of engineering you've ever seen.
