So are the pistons that fit in the holes...
It should be a little heavier like rumblefish said, but not that much where the suspension would ride that much lower...
Maybe it's the carb.... Two barrel to four barrel... Lol...
Crank up the torsion bars with the torsion bar adjustment bolts like rumblefish said until you like the ride height. Bounce the car front end after adjusting and take for a ride to let the adjustment "settle" after adjusting the bars.
