Let me know if you need any particular spares for those Stroms I have quite a few kicking about. I can also have a look through my box of Imp distributors and Camshafts. Unlikely I would have an early Sport 41132 dizzy though but I may well have a half decent 157 cam and possibly a carrier plus I can ask about. Is the Cam and carrier in the 533 goosed?
I am just having a clear out of my Imp engine spares shortly (engines and transaxles sold and being collected soon) so will be going through other boxes of stuff.

You state above that the 41122 is a Sport Stiletto - no doubt you found out since that's a stock MK2 HC dizzy.

Stiletto / Sport is a 41190

Hi there. Yes I was just reading back on the thread there and forgot all about the disrtibutor. I haven't looked at any resources about it for years so not sure where I got that from but makes more sense as why would someone have put a 1972 Sport distributor on my car?

I think the cam/carrier from my 533 head are fine but I was under impression they weren't correct for the Sport head....

Would be great if you find a Sport cam/carrier tho

Now I'm away to read the link about the distributors lol

[Darkspeed]

The 533 head should have the 157 sport cam and carrier and run the double valve springs which is why it also has the oil drain on the head - just the same as the 180 head - the only obvious difference are the inlet valves being the stock size. However since the interchangeability of parts is quite easy in an Imp so much gets mixed and matched.

Interesting that you say the head drain on your 533 was plugged - if that's the case and it has Sport set up in there it would have got through oil at an alarming rate.

I guess you are also on the look out for a Sport filter assembly with the cooler take offs as well - Not sure I have any of those in the spares but they do come up an ebay regularly although the prices are on the rise.

Dizzy info from the 12th edition "Chrysler" workshop manual.

Early sport dizzy - 25 D4 - 41132
Later sport dizzy - 25 D4 - 41190
Very late Twin Carb - 45 D4 - 41457

MK2 - 25 D4 41122
Very later Single Carb - 45 D4 41456

Now am curious about my cam and carrier from the 533 Darkspeed

I had read before about the similarities with the Sport heads but either it didn't have those parts when I removed it or I didn't look assuming they would be STD. And yes it is strange about the oil-drain. I actually got in touch with previous owners and a guy from a firm who owned it in the 80s told me about the head getting changed and I believe I met the guy who did it (and he's still alive) but he was a 'character' and it was hard getting sense out of him.

I am also veering off in the direction of the Sport filter but not read-up on that yet. Will need to get the Parts List out and familiarise myself.

Am not sure which resource I looked at before regarding the distributors as I have a new PC and it's not on my favourites but I found this one last night which is not Imp-specific but is quite detailed Lucas Distributors

[foxy99]

Just looked at my Imp-range parts-list and it only goes up to 1971 so doesn't cover the 533 head which was introduced late 1973 apparently.

I did however find this (in relation to the 533 head) on the The Imp Site

From late 1973 on.
Normal Mk II size valves and a '2' on the casings, but it has an oil drain like the Sport heads, and it does not use inlet valve seals. This was made necessary by the fitting of the Sport cam, tappet block and double valve springs to all cars from 1974 on.
It can be distinguised from the Sport head by having a thinner casting.

Am not sure if I'm reading too much into it but it could be taken that the heads were introduced 1n late 73 but the Sport cam/tappet-block not till (sometime in) 1974

[Darkspeed]

If its a 533 and it does not have the sport cam etc. it would due to someone buying a bare 533 head and building it with stock cam and parts. Would not be unheard of but you would be pretty unlucky.

[foxy99]

checked the parts tonight and the cam and carrier that were in the 533 are stock. No big deal as you see the Sport cams for sale quite often

Luck is definitely not running your way with engines at the moment is it... I wonder if all the sport parts - double springs etc. the lot were taken off it before it was put together eg. complete MK2 spec but with a 533 casting.

The vast majority of my "Standard" Imp stuff will be going at the start of September so if you need any bits for the carbs do let me know.

Cheers Darkspeed. I've not had a good look at the Strombergs yet but there may well be some bits missing. I'll also need to check for the Sport springs etc as the Sport head I have is bare.

Just got a cam & carrier for £83 inc P&P off Ebay. The guy listed it for £95 but accepted my offer of £75

One more piece to the puzzle

[foxy99]

Not much to say really but here are pics of the Sport cam & carrier


Sport cam & carrier - £83.99 inc P&P



the marks which ID it as a Sport cam


carrier for Sport cam has these reliefs/cut-outs to allow taller lobes to pass by

[ovimor]

Prices.... eh?

BITD when you couldn't give Imps away, or Mk1 Escorts...

I happened across a sad case in my breakers (whilst looking for Imp bits!) where the cam sprocket was removed and the cam had been crowbarred/snapped off in half >> to reveal the rear 4 followers and they were laying on the head = guess they wanted some shims .....

All things come to pass.

arseholes lol

when I go to scrappies I take time not to wreck the surrounding components. recently I needed bucket tappets for my Mondeo (Duratec). They don't have separate shims. went to yard and paid £40 for a set and when I got them home they were all the numbers I didn't need


I had them out in about half and hour and didn't break anything. After I'd paid the guy at yard said I could have rest of engine for £100 if I needed it - which seemed a bargain compared to price of the tappets



buckets removed (responsibly!) from car in breakers yard



another time at same yard I needed a door and he said £30 for bare door so I unpicked everything from it and put the bits on back seat. went back about 2 years later (to get the tappets) and they were still sitting untouched

Went through the dizzy box




23's - 24's and 45's

















The 68 dizzy is a non-vac and 40819 - is listed on that PDF as Mini Cooper S ! Interesting.

The 41127 D 1969 Triumph 1300
The 41533 - Reliant BUG !

The other two are deffo Imp

41456 - Late Imp single carb
41457 - Late Imp Twin Carb Sport.

Unfortunately no early Imp sport - but I will keep an eye out.

[foxy99]

that's great Darkspeed. You should mb get some of that stuff on Ebay. Make some money & space

I've now got an Sport oil-filter housing c/w hoses on the way so the last piece of the jigsaw really is the distributor. Am sure one will pop up. I've never advertised on Facebook groups for parts before but tried it for the housing the other day and got one straight away.

What might the difference be between the early and late Sport dizzies?

An just for the hell of it here's a wee glimpse of the Imp. I gave the door a bit of a polish the other night when making things ship-shape in the barn. What's left of the original paint comes up really nice so I'm going off the idea of a concours bare-metal re-spray. Mb try and retain its patina...



car was sprayed black in the 80s. 'Pacman' munched it back to original Glenalmond Green

[foxy99]

Ok. So that's me got my Sport oil filter etc. Was £75 (inc P&P) from a chap who sells Imp stuff. I've not tallied up all what it has cost to get the Sport bits but it's got me thinking that whoever did the swap back in 80s was mb more than just a casual tinkerer like I'd imagined.

There's actually a fair bit of stuff to swap over besides the head and he also managed to find plugs to blank-off the oil-drain pipe which can't have been that easy. It's not like they would have been sold in Halfords and there was no internet then....

I can'r quite remember but I'n sure when I met him (early 90s) he said the bits were put on a burgundy Chamois. Mb he put all the Chammy bits on the Imp but then it. Mb I should track him down again and ask more detailed questions. He also said there was a little plaque on the dashboard. iirc I think he said he took that off.

Anyway it's bee n almost 30 years since I met him and he seemed old to me then so each day that passes could be vital. I also (thru Facebook) got in touch with a guy the firm that owned it, when it was a working vehicle, but he didn't seem too keen on sending me pics. More on that another day. Here's the latest purchases

not much of an update but got the Sport valve-springs.

I don't know anything about them, haven't measured them or anything but no reason to believe they are duds and they were only £10.00 (plus £4.10 P&P)



8 Sport springs




the Sport ones are double

'Very early Sport, may even be part of an initial run, prior to production of the 'Sport'. Destined for use on competition cars, including the dry liner 998cc 'Rallye Imps', produced from the end of 1965.'


found very first version of Sport head for £80 plus P&P

Bit of a thread resurrection but as I have just come across two of these very early 107's its worth checking that what you have is 875 compliant as both of the ones we have are 998 - Now that may be due them being specifically selected but the note above from the Imp Site has me wondering if these were mainly cast for competition use with 998's.

Our 107's have big chambers for 998's so compare the width of the combustion chamber on your 107 with the width of a standard head chamber.

[foxy99]

That's very interesting for a couple of reasons Darkspeed. Thanks

• they say be careful what you wish for and when I read the chart on the Imp site I figured I needed 7010107 to be correct but it would be impossible to find (rarity) so I'd need to hope for 7010162 and settle for 7010180. So when I found the 7010107 head I thought the Gods were on my side.
  
  (in case I haven't explained before my car was a '65 De Luxe which was fitted with a Sport engine before it was registered. Afaik Sports didn't hit the streets till Oct '66 so my car must've had a really early engine)
• It didn't cross my mind to check if my head was 998cc so I will check that very soon. If it is it means the correct head for my car would be 7010162, unless the very early head came in 875 and 998 version

[Darkspeed]

107 - for a 998







180 - standard
