Hi,
How to make the difference when you see one? Chassis or engine number, some visible détails?
Thanks

The rules are very simple: If you're selling one, it's an HC. If you're buying one, it isn't.

Short of stripping the engine there really is no reliable way to tell. (And given the wide variety of aftermarket cams available now even that may not give a black and white answer.)

I have an HC - it has got HC on the log book, on the VIN plate it has HC, badge on plenum says HC (I know anyone can change the badge), last characters on the engine number are HC and when i had the rocker covers off it had double valve springs.

I know all cars are different as this has been covered quite a few times... wink

looked at the power outputs the standard 4 l 240 bhp and the hc 270bhp .i think thats rubbish, ive drove both and the standard drives smoother less shunting .the good thing about the hc ,you have more cam choices when replacing due to the concave pistons .if i had my choice again i would go for a good standard 5l and leave it alone !

There both rubbish figures,but if you drive both cars back to back(healthy ones)you can feel the difference,agreed about the better low speed manners though on the non HC thumbup

Hi,
thanks for the infos!
another question: 220 bhp on a rolling road session is normal for a 400hc with sport cam,rebuilt head and low mileage?
Is it at the wheels? normally the HC has 270 bhp at the flywheel on the TVR paper confused

forget the choice between the standard 4l and hc , both are as good but i would choose a very late 450 or the daddy 5l .ive noticed the 5l even sounds different from the exhaust more beefy.

it is this one http://www.pistonheads.com/sales/743287.htm
or if you know a fine 4.5 or 5L in this condition, around this budget!

Daz, Dont forget there is considerable variation from car to car. And unless you have driven many from each model i dont believe it is possible to get a proper opinion of the differences.

yes after the 2500M even a basic 400 could be a rocket !!
seen also a 4.5 99 blue low mileage, perhaps a better choice?but the wheels and interior color!!

Comparisons of most cams against a worn one would undoubtedly be favorable. The higher, rampier cams are also obviously more prone to wear than softer ones. A cam change may well change the whole character of engine, and what work for one (engine or person) may not work for another wink When it comes to cams you can either take an educated guess/risk or throw yourself at the mercy of say RobRob and try telling him what you want plus the spec of your car. I'd do the latter every time hehe

Agreed, I drove a standard and HC and you can feel the difference but the chassis was dog pooh on the HC and great on the std, so went for std and probably spent the same ammount getting power I would have spent on the chassis biggrin
