I have a 2003 T350c Red Rose. I have the sales invoice from the previous owner which shows full RR spec and 4000cc.
I bought the car two years ago and the V5 states 3605cc.
Is this correct?
I fellow TVR driver at the Caldwell Park track day thought it was a 4000cc, so I'd be interested to know which is correct.
My insurer cannot find a T350c 4000cc on his system for want of trying.
Separately, I had a T350c a few years ago that was not a Red Rose, and the performance of the two cars is very similar - up to speeds that I would reach on British roads that is!

I'd say the insurer hasn't got one listed because it is a modification, and probably why the V5 was not updated is because the premium would increase for the owner.

I have a T350 RR with a 4.0s engine. VIN says its a 3.6.
I am guessing that most, if not all T350 cars that left the factory with 4.0 engines will be registered as 3.6, but that is only a guess!

The would have just been registeref 3.6 for v5 purposes. Don't think there is an easy way of telling, there's not even enough difference in power to get a rolling road to confirm for sure as some 3.6 perform just as well as the 4.0.
Just enjoy it, if it ever needs a rebuild you'll be able to have the bores/stroke measured, if you really need to know I'm sure TvrPower or the likes could spot the difference during a service or something.

You can reasonably easily take out a sparkplug and measure the stroke with a piece of dowel . Put the dowel down the sparkplug hole then mark the high and low points as you turn the engine over by hand .92mm 4.0 or 83mm 3.6

Thanks for your replies.
Seeing as the DVLA and my insurer are OK at the moment, I'll let sleeping dogs lie.
I may pop into the garage with a dowel at some point though!

Build sheet should identify what it should have been built as.
4.0 and 3.6 are very different so driving two cars back to back should be enough.

Str8six did show me how to read the car's vin plate recently showing mine was a 4lt. as we had had this with a T350 red rose we had just bought.
As it was explained to me the early red rose cars where blue printed 3.6's but this proved time consuming and costly so later RR cars where sent out as 4 Lt's with the different RR injectors, exhaust ends etc
