I run an 800 AVS on a Modman on a G3 6.1 Hemi.

Ive had significant issues with launches...just couldnt tune the lean bog out...even with drilling
the pump shooter.

Air door tension made no difference - it would stall no matter what.

So I trialled an 850 Holley dumble pumper on Sat....bog disappeared completely.

Since then other guys have told me that the Modman combined with big head port runners needs BIG fuel at launch .

Otherwise Ive found the Modman to be very responsive off rolling starts.

I thin Tex is right...its probably ideally suited to a stroker or dual carbs.

LOL I thought you'd never run a holley carb??



Im not....used for diagnostic purposes only...

Ill be going dual 500 Carters as soon as I have the coin.....

Care to donate to the "keep Mal's car a Holley free zone" fund?
