Thanks for the kind advice. It is an engine that has done 2000 miles in an automatic Ford C-Max before the rear of the car suffered from fire/smoke damage. The whole front was untouched - and no impact. It has new R400 valve springs and new cam shafts. I am so lucky to have a friend who is a former race mechanic. He did the work, and applied some sort of lubricating paste to help with initial fire-up. Hopefully the engine should be run in except for cams etc. The valve springs were changed with the head on using an American tool called Valvemaster, which worked superbly if anyone needs to do this. After a very long time working on this car, that was supposed to have been totally rebuilt by "experts" in the kit car industry, we ended up virtually re-doing everything. We found countless dangerous incorrect fasteners, wrong size washers, wiring problems, completely shot (supposedly reconditioned) shocks, trapped bolts under the fuel tank straps (an explosion waiting to happen!!), even the 4 point harnesses were fitted incorrectly. The steering column top bush was a roll of insulating tape . Several well documented features were also not on the car. After 12 months of head scratching, plus nearly double the budget, it is almost there... ...well nearly almost
