4.5 big valve chimera
Discussion
Chimera registered in 2000 advertised as 'fitted with special 4548cc big valve serpentine engine, fitted by factory as no standard engine available.' Said to develop 312hp. Apparently a letter from TVR Engineering confirms.
Car was supplied by Brundle TVR.
Can anyone shed any light on this? I would have thought that the engine spec would not be the same as the 4.5 bv fitted to some early Griffiths. Would this just be a standard 4.5 with big valve heads?

4.5BV is 4441cc (80mm stroke), at the capacity you mention it sounds much more like a std 4.6 (ie TVR 450 ala std Chim 82mm stroke), possibly its just that they stuck nicer heads on it or it was ordered as 4.0 and they upgraded due to shortages.
TVR Power are likely to be able to tell you for sure.
