what's your h.p opinion

hello and thanks for your replies. i am new to this forum and find it very cool, so heres my question. my 91 gm tbi 350 has been redone. i put complete edelbrock pwr pgk. heads 64 cc 9.5 comp , cam , intake , roller valve train, chipped to match , accel module , mallory ignition, and adjustable fuel pressure regulator . my timing and fuel pressure are what ive been playing with lately but it don't seem to be dialing it in . i know its not a sports car but i want more. seems lacking on power. i would love to here some ideas of what next. oh yeah stock tbi unit. :confused:

hey, spindles... this link (if it works) points to an interesting article

yes i have read that site and some similar as well, i have injector spacer stiil in but took my tbi spacer out cause i thought the edelbrock manifold would flow well without. now that i think of it maybe its my budget cold air intake not flowing at higher rpm. if i crank up fuel pressure i crank out huge bottom torque but lose power at upper rpm.
