Difference between 500HC and 500?

[Azzurri]

I know HC means high compression but is there any other difference such as bhp or 0-60 times, also would the HC engine be more reliable? another thing that suprised me is the size of the engine for a 5 litre, it isn't as big as I thought it would be, has it been compressed in any way by Rover? thanks...Gav

No difference. As far as I know all 500s were HC.

Yeh... from memory there is none. I'm sure Steve Heath will correct me, but I believe the last few years of the 500 were dropped from 340bhp to 320bhp to make them easier to drive in town. Obviously these figures were... well... and estimate anyway so I wouldn't worry.

Cheers Dan

OK, but do all 500's have high lift cams or just the HC? but also I was told by a TVR engineer at Proactive that HC stood for high compression, nevermind.

The difference between a 500 and a 500 HC?

1. Holed exhaust as the extra noise is due to the power.
2. A different badge on the plenum available from Leven tech and TVR.

Basically all the 500 cars are the HC spec despite some initial docs that referred to seperate varients. There are a lot of variation in the techie specs that TVR have released over the years including a 500 engine that was under a 300 bhp that appeared in a Wedge or two and so on.

The HC as in the HC on the 400 and 400HC Chimaera/Chimp/Chim-puppy/Karmara (for those down sarf) and is a hotter cam. The compression ratio has basically stayed the same.
