whats wrong with my setup? the car is 2000 z28 full weight
built a4 w/tci ssf3500
mti lid
233/239 595/605 112lsa cam
lt headers
true duals with x-pipe
3.73's
lca's
adjustable tq arm
panhard rod
weld pro stars 15x3.5(mt sportmans up front)15x8(26x11.5 hoosier qtp's)
the car was running 12.50@109 before the cam. after the cam i picked up .4 at the 1/8th and only .3 at the 1/4. my 60' times are 1.70-1.71's and the trap speed went up to 111mph. i know the stock ls1 intake and unported stock tb. i was really hoping to get the car into the 11's on motor. i now have an ls6 intake, 28lb injectors and getting a better fuel pump going in the car. do you think these changes will help any?

i always turn the key and wait for the fuel pump to stop cycling before i turn the engine over and i used to be able to hear the pump very easy. now i can barely hear the pump at all so maybe the stock fuel pump is quitting. i just ordered a walbro 255 though so i should know pretty soon if that is my problem.
