Engine loss of power at 4K RPMs after Motor Reinstall.

[MJP]

Hello All,

I had a #3 Rod bearing go bad a few months back on my SE-R.  I pulled
the motor, replaced the Rod and Main bearings, new wrist pins on the
pistions along with rings, and a new gasket kit.

I put it all back together, it starts beautiful, idles nice and grandma
driving is good.  But if I want to jump into traffic, it looses power
at about 4000 RPM's, but if I grandma drive, I can get up to speed ok.

When I first put the car back together, the flap on the Throttle Body
was stuck closed, and I don't think that is jamming now... but that is
where I come to the infinate wisdom of this list.

Any suggestions or questions to process a diagnosis?

Side Note: When I put the car back together, I did so with stock
Intake, Exhaust, and Header. The only upgrade on the motor currently is
the Cams, JUN Ultralight Flywheel, Stillen Stage II Clutch and PP.
