    Software Says.....16.4psi @ 5800 rpm. You really need a 70mm T.B. the program says to reach 503 rwhp @ 75 degrees 80% humidty total timing at 19 WOT.

    with race gase and some timing you'll only need ~ 13!

    My old S-trim on buddies 302 and sytemax II and 13 psi made about 530rwhp on 110 w/ somewhat conservative street tune
    351 "stockshort block": -Vortech T-trim (21 psi), Trick Flow Heads, Lunati Cam, Weldon fuel system, Lentech AOD., 3.55 gears, 27" Hoosier QTP's, 3500# with me

    -545 rwhp
    -10.02 @ 135mph---Is 9.99 to much to ask?:freaks:
    -1.42-- 60'

    Thanks for the reply guys. So it looks like a 3.12 or 2.95 pulley and 70mm t body. Any thing else?
