I would leave the stock cam in it until you convert it to mass-air. That's JMO
The speed density computer can not adjust for the air difference needed for an aftermarket cam Last edited by 89five0Gt; 04-10-2009 at 06:50 AM. |

+1. You CAN throw some 1.7 roller rockers on it though. This will bump up your lift & duration on the stock cam. Somebody used to make a SD friendly cam a few years ago,but I forgot who. It's pretty easy to convert yours over to mass air.

If it's mild enough, you can compensate with some fuel-pressure... but I wouldn't recommend anything over about 212ยบ duration.

Negative,they do affect the duration,although it's a small amount compared to the affected lift.

B303 will work on a SD car.
I ran one for near 2 years with no issues at all

duration is the time the valve opens, the rocker just effects how far the valve opens

This is true,however the increased ratio on 1.7's also causes the valves to open earlier,and close later. Ed Curtis explained it on the corral. I'll see if I can find the thread.
