hello, sorry not been around for a whlie!
The van is currently undergoing a gearbox rebuild/overdrive conversion. Its an Autosleeper conversion, the most common one out there. I've been in touch with the company (still running!) and they seemed quite interested in the older conversions. (Or just wanted to get a babbling weirdo off the phone!) The nice thing about this conversion is that it was fitted to loads of other vehicles (bedford CFs, Talbots etc.) so there are quite a few other people out there with similar interiors. There were about 3 a the NEC.
I've just got myself a humber sceptre engine (the alloy headed one) so I can try to get some performance improvements. I'm also toying with the idea of throttle bodies - has anyone done this to a rootes 1725 before?
cheers
Rupert

hey bigmonkeyman (take it you have a monkeybike too??) is it the hunter engine or the earlier sceptre II engine? not sure on throttle bodies being done on this motor but I am contemplating bike carbs on mine for that lovely induction sound.. also these carbs being modern will hold their tune well I would think compared to some rattly wheezy old carb thats been bobbin about for 42 years....
I found with the commers the worst thing was the low ratios of the gears, obviously this was down to the rear axle ratio which was designed to get the van up a hill using the meagre power of the iron head engine..
If you think your iron head engine is seriosuly gutless for no apparent reason then check the headgasket on them, it wasnt unknown for these to be fitted with the copper asbestos headgasket during a rebuild which effectively ruined the compression ratio as the proper gasket for the iron head engine is a pressed steel gasket and amazingly thin..
you should be able to see from the side of the engine/head join if the gasket it wrong, the steel ine is barely visible almost like no gasket is fitted whereas the copper/asbestos one is 2mm thick
(modern composite ones are also too thick for the iron head engine in all honesty)
hope this helps. using the camshaft out of a later sceptre could free up a couple of horses as well.. speedy spares do a range pf pistons for this engine including a holbay type non dished piston which gives a good hike in compression.
another thing to bear in mind with fitting an alloy headed motor is that if its the later motor wou will need to strip the entire front off of your old engine to go on it (think the mounts for the motor are on a large plate behind the timing gears on the early engines-this maybe only on the cars though in which case youll be ok) also your existing manifolds will not be suitable due to a different valve/port layout..
a mk1-2 sceptre exh manifold exits straight down so this would probably get you out the stumn... and I have an inlet manifold suitable for an upright engine if you get stuck.(also have some for sloping motors)
if you need any more info please feel free to PM me
