power

lets start with my combo. 87 gt. 3.73s, gt40y turboswirl heads, explorer intakes, e-303 cam, 255 fuel pump, shorty 1 5/8 headers, pro-chamber pipe (with exhaust leak), cold air intake, mass air conversion 73mm mass air, 70mm throttle body and spacer.

questions are
what do you think power would be
what am i missing to get complete power out of my combo, (dynotune, adj. fp. reg)

any help would be appreciated, im feel im at a standstill but i know i need suspension

well at least someone has an idea.
