I found a custom compcams grind cam@

• Duration (Intake/Exhaust): 226°/236° @ .050"
• Valve Lift (w/1.5 Rocker): .463"/.474"
• Lobe Sep. Angle: 112°

Im running and edelbrock 3790 cam now( http://www.summitracing.com/parts/ED...5&autoview=sku ). Would the custom be too much for a untuned ecm? I'm running a 3.4 with 3.4l injectors, 1.6 rockers and a AFPR. I want more torque and midrange power.

 

My motor idles like crap below 800rpm and that one has more duration than I'm running. But mine's on a 115 lsa so that one will be alot more manageable. 1.5 rockers would probably give you better low to mid torq.

 

Would my stock ECM work okay with it?

 

Most likely.

 

With a cam of these specs:
Intake Duration at 050 inch Lift 204
Exhaust Duration at 050 inch Lift 214

Lobe Separation (degrees) 112

and 1.6 ratio rockers, will the valves kiss stock pistons?

 

I need specifics on what you're building, but I really doubt it.

 

I'm just looking for more n/a non-hybrid hp. I've come to the realization i will be losing low end torque so I'm just looking for a larger cam then the one I have. I also already have 1.6 ratio rockers.

 

the closer u can get .500 or above lift the better the iron head flow jumps up considerably after 400 lift. while its mid lift numbers that m,atter the most going to a cam with .515 lift will give u a decent gain over a similar cam with only .430 lift

 

Do you have any high lift cams in mind?
