opinions on dropping a 77

[shortchev]

Hello Guys ,
I am new to this forum (was a Impala ss forum junkie forever ) sold all my cars and bought 4 trucks , go figure . Anyways I have a 77 c10 that I have dropped with a rear flip kit , cut springs ( 1coil) and spindles (bell 2 inch). The wheel and tire package I have is Boyd Evolution 17x8 on front (255/40/17 tire) and 18x9.5 rear (275/40/18 tire) Thing is , I just dont think its low enough and dont like the look . I would love to bag and 4 link the truck but the budget dont allow .I was thinking maybe using shackles and hangers in the back, is this possible with already having a flip ? I have stock rear springs in (none removed )
Also on the front I was thinking of Z ing the frame .What would be the pros and cons of the Z and what would be the best amount to Z 2-3-4 inches ? thinking of just using front bags and schrader valves .

Any opinions on the wheel and tire sizes ?
A few questions , I know . Thanks In advance, Be patient I am new here , just discovered this place and I have alot of questions . Pete
