Desktop dyno help needed
I just wrote another thread asking for info on taking my valve lift from .488 to .518 relative to valve clearance via different roller rockers. But, If anyone has a desktop dyno and would run my numbers for me, I would appreciate it. I want to know just what kind of HP and TQ increase I can expect from this. Here is my engine info:
302 with 8.5:1 compression, Edelbrock aluminum heads, single plane intake, 700 CFM Holly, MSD ignition, Large tube headers, 3" open exhast. Cam info:
Now:
288 total duration
228 @50
.488 lift
Lobe displacement angle 108
Planned:
288 total duration
230 @ 50
.518 lift
Lobe displacement angle 108
So, If any of you fine people can run my before and after numbers, I would appreciate it.
thanks
Ed
