Can anyone help with what the stock cam specs are for the 2L pinto sohc. I've searched everywherec and I don't seem to be able to find them.
Thanks

My files list std spec as
Inlet 24/64, duration 268
Exhaust 70/18, duration 268
Overlap 42 deg
Lift 0.399"

Thanks jimmy.
Should my cam turn out to be not suitable.
Any one recomend a good grind for an overbored 2L 10:1 compression. Forged pistons. ported. large valves, cc'd. balanced. twin 40mm dcoes. pacemakers and to be driven primarily on the street with the occasional barbegelloes run?
 
 

I have heard good things about FR22 & FR32.
 
You are better off contacting somwhere like Clive cams or Wade cams and havingha a chat as they are the dudes who make them and can recomend something that will suit.
 
Cheers,

The lobe centres are too wide on the standard cam. Plus the intake lobe c/l is too retarded for my liking especially with a milled head.

You need to know your rev range, power goals, and redline to select a cam. Upgraded cam will likely need heavier valve springs too.

 
sorry spigot, i do have stronger valve springs. and long pad followers.
I guess i would like power between 2-6 .
being a street car i want the power down low. having said that i also
don't want the waste all the work i put into porting and valves n stuff.
The cam i have has 40 ovelap and .47 lift but is a 20/60
Maybe its just timing but it spits alot.
Since i have to take the motor out next week - "dave" has me reviewing my cam choice.

so this is pretty much my cam.
hi torque low end.

Do you have your actual cam specs?

What is the cranking psi of your motor?

What is wrong with your current cam??

The lift is .47 so i'm not sure what the .29 is (lobe lift??)
not sure on psi.
well it's not that quick at the mo - but still alot of jetting to do. My main concern is the spitting out the carbs.
It's more Dave suggesting it is a very short inlet time and it's somewhat different to what he's used to seeing. he showed me a couple of cam timing sheets that he thought it should be more like.
My choice for this cam was simply that i want the power "off the mark" since on the street you just don't get to rev it out much.
I still want that - but then it would seem a shame to waste all the other work by stiffling it with the wrong cam.
i guess since the motor is coming out he's suggesting i review the choice.

If you haven't set it up properly on a dyno, how can you complain that's it not doing what you want it to?
 
Carb spitting is a lean issue I think.  At least it is on my bike carbs.
 
Good luck
