iv bought this
anyone know what type fly wheel it is?
the clutch is AP Lockheed sinterd clutch plate & cover plate
does anyone have any info on the clutch?
it has afew numbers on the back of the fly wheel GM 90 209 935 165 There are some more numbers but half have been ground off
The clutch plate says TILTON some has wrote in pen 64185-0-a-30 1x23 12,208 prob means nothing
the pressure plate says ap racing England
there are some drill marks which look like balancing marks
flywheel part no is deffo vauxhall
looks like a lightweight (maybe 3-4kg?) flywheel (possibly from sbd or qed) with a mount for a 7.25" clutch which looks like a single plate AP
uprated/race clutch. I've just bought a similar AP clutch except mine is a twin plate type. I also have a 2.5kg flywheel which is lighter than
the one in the picture. should allow the engine to rev more freely, nice upgrade
Drill marks are often used for balancing, are there correspndong marks on the flywheel, pressure plate and spacer plate on the clutch? they should all
be aligned so you reassemble the clutch in the correctly balanced orientation. Assuming they have been used as one piece (ie flywheel and clutch)
before, then the balancing should be ok, unless they have been balanced as one piece with a crank as well.
1x23 is 1" x 23 splines which is ford input shaft spec ie for a type 9 box.
Ned.
ps i've been told my twin plate is good for 280-300bhp, so i'd guess your single plate should cope with 2-250bhp, though this is only a
guess!

thanks for the info Ned!
its got balancing marks on all 3 parts
been to a mates tonight and he has advised me not to use this as it will be far to harsh for day to day use 
it would be perfect for sprints etc
so ill be selling it on so ill put it in the for sale section soon
Change the sintered plate for a ceramic paddle plate and you will get more drivability, i.e more slip.
Ned, you disapoint me. You should know by now that clutches are rated by torque not power.
