Well this is great. But what a job. I started looking at my Imp engine this afternoon, with your video in mind, and I could only think: OMG where do I have to start! Good luck with your Imp engine!
Brings back memories,I had a 1040 Andy chessman greetham engineering unit in my road car with a R21 cam on janspeed combined inlet and exhaust manifold with a short ford transit back box very loud on45 delorotos very fast in the 1980s cheers
Looking forward to that video Imps have always been a favourtie of mine we built the first one almost entirely with hand tools no electric in a lockup garage years ago
This stuff is so good. I had a sunbeam sport back in the day. The one with the twin headlights but not the fastback. 875, but came with a highlift cam, twin Strombergs, the 4 into 1 pipe and the oil cooler. Think it had servo brakes unlike an earlier one I had. Great fun to drive. Always wanted to modify it but never got around to it. Lovely work in that engine!!
@@thehillmanator always wanted the rallye but they were like hens teeth even when I was a kid. I remember replacing a door on the old car from a much newer one, there was a huge weight difference!! they must have cut the gauge of the door skins down considerably at some point. Loved that Sunbeam, it would just touch 50 in second but the red line cut in like a switch, I think at around 7500rpm... which was mad considering the age of the design. After I got it I got the carbs tuned by someone who knew what they were doing, also fitted a new chain to stop the timing mark dancing around, new plugs and leads, rotor arm etc, actual bought a micrometer and a bag of shims to set all of the gaps correctly... ran like a dream.... good times, happy memories.
Did this engine ever have a 16 valve head for some reason i remember skimming and setting the valve clearances for someone who had a 16 valve head for a hillman imp apparently
Years ago the late Pat Mannion, who owned Revolution wheels and raced imps in the Wendy wools special saloon series had the moulds to make castings of twin cam heads for the imp, but unfortunately I don't know what happened to them.

Thanks for comment, yes the sunbeam imp sport is becoming a very desirable variant, like the “cooper s” of hillmans !

Top man . Fantstic job
thanks, the clever bit is done by others i just glue them together 🤣🤣
Awesome!
thanks, will get a follow up video on soon👍
Whats the beans in it then ?
Very very tasty...yum
Looks promissing! 🤔 Is the top plate used to get more stroke and maintain good rod/crank ratio?
correct yes two spacers if you look closely 5 mm for the strokes crank and 16mm to attain correct rod to stroke ratio 👍

not that i know of.

@trevorhows3281 This possibly could have been one if I remember right it had a lot of other parts from the 8 valve
