T350c Red Rose Engine

[NailedOn]

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!

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.

Which raises the question as to where I would find the build sheet? (I am the 3rd owner from new.)
