You notice all that low end torque you lost.

Yun,
It was great seeing your car looking good and running strong on Saturday and thanks for allowing me the test ride yesterday! It was a kick to drive and not have the lag of the seocndaries....WOW! It was great to get a preview of what my motor will be like in the months to come!

Looks great, glad you are happy. The extra 30 cubes will be fun.

Honestly NO! No change in drivability, no change in fuel consumption(nothing perceptible), runs really strong. Really clean under the plenum too.
Mind you, I am chasing a few things like light stumble as I tip into throttle after coasting in 5th around 1800 to 2000, seems to run rich at idle, rpm drop while idling (think I fixed that today by adjusting idle set screw, low oil pressure at idle, etc... Expecting the motor to run perfect after a major surgery is unrealistic. Imagine it will take awhile to get everything set up just right. All said and done, really happy with the result.
I developed a lot of respect for outfits like Lingenfelter, Marc, Pete and others to modify and deliver sorted out cars.

Thanks. You are going to trump me with exhaust cams.

Pete,

What loss? If there were any loss, sure made it up with extra cube.

He was joking Yun, alot of people discuss the possibility of torque loss, but obviously Petes car runs 11.1 @129 without them.....so no real loss there

I know he was being sarcastic. I followed those discussions.
Did I mention how awesome it sounds with extra cube, higher compression and cams?

Some of these issues won't be addressed mechanically.

Like a drag run would show any sort of torque loss that may or may not occur under 3000rpm, or at part throttle at low rpm.
