Hi all

I've been stripping down the engine on my 400 HC and I belive the cam is pretty worn. The two lobes I've had chance to measure are showing 6mm and 8mm lift and I'm led to believe this is not good?

What's a good replacement cam in this situation? Not looking for anything particularly stellar but whatever might be ideal with the car in pieces.

Cheers

James

Well I'm glad that's narrowed it down, thanks people biglaugh

Firstly, do those readings point to a new cam?

And besides the V8D cams, where do you actually look to get the others? Like I say, not looking for anything radical just whatever is worthwhile with the engine apart. I

I presume I'd need to change lifters, timing chain and all gaskets too?

Cheers

Stuck a Range Rover cam in my current engine......not suggesting the OP does.
I had a stealth cam with my 5 litre engine, it gave me a really good level of torque over a very wide rev range. No idea if this would help a 4 litre.

First question, what driving are you intending?
General B road etc on a Sunday,
commuting,
long distance touring,
track days?

Second question, what is your driving style/ other car(S). I found the wide torque range great because I am slightly lazy with gear changes and tend to drive larger engined, diesel automatics. But I also enjoy a track day or 20, and the stealth cam on a 5 litre engine made for a great track day car.

No real commuting. It'll be my only car but I won't cover much distance. B Road stuff definitely.

I tend to use the bottom end of the Rev range more, so a good chunk of torque there would be handy but I wouldn't want to miss out on a lively top end.

I think I'm leaning towards the Stealth Cam as I've checked and it's got double springs and pocketed pistons, so I think it would suit that setup?

Does V8D supply the shims to set the preload too? No idea how to do it but I'll find a thread

Well from what I've read I'm torn between a Typhoon and Stealth cam.

Is there much to separate them? And I presume I'd have to fit a vernier sprocket to time them right?

So Stealth, Tornado or 885?

The engine is out so should probably start on this job coffee

I'll look at the 885 cam then, seems a popular one!

Anything else worthwhile doing with the engine out? Body coming off too but that'll be another thread ;-)

Does anyone know how much lift the TVR 435 cam should be giving?

Just pulled the cam out and it's got a vernier timing set and immaculate lifters. I've got about 7.2mm on each cam lobe. Does that sound about right?

Looks very much like the cam has been changed at some point then...
