Can anyone advise of the cam timing on a STANDARD cam for a 500. I have been given two different figures.
Thanks

Seems you're not alone! From what I can see it might be a 885 or a 214/234 or a 435!! http://pistonheads.co.uk/xforums/topic.asp?h=0&...A call to Dom @TVR power might be best. Regardless of what you have - when timing in the cam the figures you need are the crank degrees advance from TCD @ .050" cam lift Don't use the LCA method to set it as this assumes that you have symmetric lobes which is not always the case.

Thanks for the reply. I will have to take the value given by TVR Power @ 111.25 BTC. The other option was 116.

Thanks chaps. Not fitting a new cam, but having to re-time the one that is in the engine. All due to a broken crank pulley bolt.

I would like to see the changes to the torque curve if you retarded the cam timing by say 3 degrees... A before-and-after overlaid plot would be interesting.
