HC how to tell?

[nickc]

How can you tell if it is a HC model or not, will it be stated on the logbook?

[iandbeech]

In the process of buying 4.0l HC, have a look on the engine, you can`t miss it.

400HC badges cost around £10. Check the paperwork and make sure. Apart from stripping the engine there is no real way if there is no corresponding paperwork.

If you can take the plenum of look down the trumpets the inlet manifold should be smooth and show machining marks, (standard ones have a rough cast surface)you may need a torch, this would take 15 minutes,
check with TVR the engine number to.

Maybe a silly question - but where is the engine number?

I have a 93 4l Chimera 250 which according to Steve's book indicates it is gas flowed. Would this look the same down the inlet manifold as an HC?

A small oblong block sticking out under No 3 plug (2nd one back on the near side). It should be stamped with the TVR engine No. which should correspond with the VIN plate and V5 .
It should also have a HC suffex for a HC, mine has, but if it doesn't don't panic as TVR weren't consistant with this I'm told, Tims way is probably a better indicator.
The block may need a wipe with a rag to see the No's, but being ally it cleans up a treat, you'll need a torch as well, and possibily a small mirror .

Nick - I use Harry's VIN plate method - look for 'HC' after the number - the V5 logbook may not have this. Also, drive it. A right 'HC' is certainly quicker. Happy hunting - don't rush your choice - cheers, T

Yes if its a gas flowed version (which the 250 is) it should have this. I thought they only produced 250s on the early Griffs during 92'.

You can't tell by driving it. I've been in plain 4 litre cars that were quicker than HC ones. The VIN number is not reliable as the number ing was not consitent and it is easy to punck a couple of extra letters. And it has been done, especially when cars are not shifting.

If it has history then fine, if not be suspicious.

And it may not be there either... Also seen numbers stamped at the back of the engine and on the bell housing!
