Hi There,

I'm trying to identify a Rover V8 engine in a car I have bought. The owner states it is a Rover engine from a TVR Griffith 500, therefore a 5.0 litre capacity engine. However, looking at the engine number, it seems to be a 4.6 litre engine maybe from a Morgan? the engine has "500" on the plenum and TVR on the valve covers, it also has a T5 gearbox rather than the LT77 that so many are fitted with, but I guess they could all have been fitted afterwards.....
I understand the TVR 5.0 engine had a higher CR than the 9.37:1 stamped on this one.
Would anyone on here be able to help me identify it?
The engine number is S46D44990A

Many thanks

Simon

Yes, I've been on the usual websites (Rimmers etc) but the nearest I can find is the Morgan ID

Thanks for your help gents. The previous owner had the car Dyno’d when he fitted the engine and it made just over 290 BHP. I guess that’s well short of the 340 BHP that TVR quoted for the engine, but still pretty respectable for a Rover lump. Even if it is “just” a Morgan engine I’m pretty pleased with that.
