Chimaera 500 camshaft fitting advice (stealth)

[4iturbobob]

Good evening all.
Have purchased a stealth cam kit from V8D for my 500..
it came with a cloyes timing chain set which looks the part.
This has fitting instructions for Ford and GM engines but not the Rover.
Do I assume that that it has to be fitted at zero degrees (tdc)
Also the cam never came with a cam card??

Would appreciate any advice from anyone that has fitted one of these..

Thanks

Rob

Hi Rob

I had the same timing chain kit (Cloyes Street Roller I think) and you're right it does have 2 sets of fitting instructions. From memory it's the GM one you want and the thing to pay attention to is the two 'o' marks on both sprockets. Make sure they face each other.

Don't worry about the cam card - you won't be able to dial much in with the Street Roller - only 2/4 degs advance or retard. Stick with standard timing and you'll be fine. Rob at V8D uses these for a reason!

See below






Hope this helps

Edited to say - I think you won't get a cam card anyway as Robs grinds are kept close to his chest!

I was going to contact you to see how you were getting in with it! Great tip about the O markings too!

[4iturbobob]

been slow chris to be honest..busy at work.
Had to change front cam bearing as well which was a pain.

ok..got both sprockets on..
do we think this is correct??



heres a shot of the chassis while I was underneath it



been giving the water tower a polish up with autosol and a scotchbrite pad..shines up nicely..

You need to dial the cam in obviously... you put a cam wheel on the end of the crank and a DTI on No1 front inlet lifter. (thats having established TDC with the other DTI) and then line up the 0 or 2A or 4A or 2R depending which way you need to go... remember 2 deg on the cam is 4 deg on the crank etc...

I tried a cloyes unit when I re-built my engine. it says you can dial in to 1 deg but I found it was actualy 2 deg after a lot of checking... problem I had was it was just past the mark one way and obviously 2 deg before the other... allowing for chain stretch you want to be a bit advanced so it will wear in over time.
they say +/- 3 deg is okay but I set mine to plus 1 with a vernier and then pinned it

I would speak to Rob regarding settings.

With my bespoke cam which should have been set at 110 degrees, the idiot who timed it set it as the standard setting which was wrong.

I used a Cloys set which was pretty much spot on with the advanced setting.

[4iturbobob]

Ill have to speak with him..the heads are still on the car but i can guess i can extend the dti to reach into number 1 plug.
As said previously no cam card...
Is the tdc mark cast on the block usually that far away from true tdc??

[phazed]

The TDC marks on Serps are supposed to be spot on, mine was.

[Chuffmeister]

Out of interest, how did you go about setting the pre-load on the followers. Did you use adjustable pushrods or shims?

so i assume that lining up the dots would be adequate??
I can do a basic check for tdc with the dti..

confused !!!!

not got that far yet mate, this will be the next headache im sure.
ive got some welding rods bent up ready for the job..
ill keep you posted.

Just want to make sure i get this cam right before i go any further

[phazed]

You really need to speak to Rob before proceeding as once fitted and wrong it's major work to rectify.

Drop him a text or call on his mobile.

[4iturbobob]

I guess ill have to call hom tomorrow..

[phazed]

I'd text him now, have you his number?

[4iturbobob]
