I did read your pm and was going to reply later tonight...

I think you mentioned in you thread that the engine cost about £800 and thought that it wouldn't be worth spending more than 1k to get it installed.

If the engine physically fits in the hole and needs mounts and driveshaft’s then I could see you spending that sort of money depending on how much time was spent making the mounts don't forget proper custom driveshaft’s (not cut and sleeved) cost about £360 plus vat so you can see that the 1k would be easy to hit. Then you have pipe work and gear linkages to sort...
