302 Ford not working...

[roffroadracing]

I have 302 sbc ford installed with these parts.

- TrickFlow Hyd roller cams 221/225 @050" .499"/.510"

- TrickFlow sylinder heads http://www.summitracing.com/parts/TFS-51400010-C01/

- Weiand maniflod http://www.summitracing.com/parts/WND-8124/

- Msd 6AL and Msd distibutor

On the dyno from engine I have 4800 rpm 502 Nm and 377hp at 5900 rpm.

I have seriuos problems at 1800 - 3000 rpm... Engine is really strugling and it sounds like its not running with all sylinders. I have tried everything... (power valve, pump squirt, a/f ratios)

What problems are you experiencing?

Is the Atomic controlling timing?

What is the timing curve?
