thanks for the info there Missioner.
i will defiantly look at the increase of Compression, makes sense.
The motor has already has an electronic ignition upgrade done, i am very happy about that.
the biggest time consumer now is just sorting my work area out now, everything is down to spare parts and it can get untidy very quickly.
As much as i am itching just to get in and bolt the motor in , i need to take my time and concentrate on the smaller things that need to be done now rather than later. Make sure everything is 100%, alot of parts take a while to arrive, for example radial control arm bushes can take up to 12 weeks to arrive, and the list goes on, luckily there is a lot i can do in the mean time.
