Hot Cams

G'day everyone...

Id just like to ask the question, What cam should i use??? i realise of course it greatly depends on what i'm planning to do... i'm looking at a new Crow Cam to suit my 202. and with this list i have, i'm relay confused on how hot i should go. i'm re-building this engine compleatly and plan to put it in my HZ tonner which ill be driving every day almost. id just like a cam that has a bit of a "lumpy" idle and gives it more grunt at hi revs (one that could hit about 6 thou). its mainly for show more than anything. to make me feel tough! lol. and at the same time to be good along the hiway! (economical). i have the crow cam book with descriptions of each cam, but id only be guessing as to which one to use. could anyone share some advice please???

Cheers, Big Mal

P.S i'm hopeing to end up with a pritty fast ute. one that will show up a ED XR6!! Thats right, my best mate owns a F#*D!!!

Hi Big Mal. Your cam question is an interesting one. I understand your driving this car daily, and would like a hot sound, more power in the mid to top end rpm's. What I'm not sure about is if your car is manual or auto, whether it has aircon or not, what carby, and what diff ratio you have. These factors in combination with your driving needs, and enjoyment needs, will determine the camshaft for you. In short though if you have an auto with a standard convertor then your sensible options are reduced. If you have manual gearbox then yes you can have a lumpier idle. Sorry to add more confusion to the mix.

Cheers
LMH

Ok guys... Well first i will be sticking to a manual. 4 or 5 speed, im not sure. I currently have a worn out aussie 4 on the floor, which id also like to ask if a stock 4 speed would be ok to use with my slighty hot engine? And it dosn't have an air con (thats one good thing about the XR6!!) and ive recently put in a 3.08 ratio 10 bolt sals (non LSD). which is good along the hiway with the 4 speed. And im not sure what ill do about the carby situation?? id like to go twin strombergs. i was hopeing for some flexibility there lol. certainly not thirsty ones!!!

Thanks for the replies LMH and snowdownunder.

PS. when you say "30/70" is that for the inlet or out let valves?

To juggle cam specifications you need to dig a bit deeper and have a look at all the third party cause and effects that a cam can have if not properly supported. March 2007 Street Machine Magazine page 108 has an article on a red motor 202 that is producing over 300 horse power.
Dandenong Engine Reconditioners have shown what testing they have done and the lengths they went to to build a bullet proof bottom end and valve train. It's well worth reading, and there is another article I'll try and dig out for you on cam specifications.
There is a web site that I use a lot that Crow Cams has.

Well hi there to all peoples out there, I have found an old cam for the holden 6, I have a simple VK Calais 6, would any one have an idea of the specification as the only ID I can see is the 4SK stamped on the end.

Great forum to exchange knowledge,

Regards Bernie
