Its all hear say the imp engine is designed on a covenrty climax and thats as close as the get , Well having had a few fire pump engines over the years plus haven looked close at them none of the parts would fit to an imp or 930 engine it all looks very simular but the bits are either to small by a few mm or to long by a few mm ,and having looked hard at the bigger coventry climax engine that is in say a lotus they are way bigger they do look very much like the imp engine ,i know that the comp dept did do a few 1190 and 1220 long stroke engines these were sand cast ,the 850 engine were down stroked to 58.4 and the bore was 68mm ,i have a sand cast front cover on my original mk1 engine and few other engine bits that are sand cast but its still an imp engine ,Any way clive if you know which bits fit to the imp engine please let us imp lads know so we can you them
