    Mark, did you go with a shift kit? or did you get valve-body work done?

    I installed a B&M shift kit in 1985
    No other valve body work done
    A TCI 36 element sprag/drum assy.
    Alto red clutches
    Kolene steels

    Sounds just like my new set up also, good luck with yours.
    look forward to seeing your results in the spring and hope it helps out some if not all of
    the issues you were experiencing.

    Thanks Tony, me too!
    Hopefully I've eliminated a variable:TU:

    Hey Mark, any updates on this? Very interesting thread, I'll be installing my SP3 soon and will be running a Qjet as well, at least for now - I've been eyeing the Holley Terminator kits.

    Hey Craig,
    New laptop here, took me awhile to get set up:eek2:
    Anyhow, I'm running an AED 850 (Holley based) instead of my Q-Jet on my SP3, the AED DP supplies the fuel on the secondary side IMMEDIATLY verses the Q-Jet with no squirters on the sec. side.
    The bog is gone, I can slam the throttle wide open, and it GOES:TU:
    My Q-Jet worked AWESOME on the Stage 1 intake, but it seems overwhelmed on the SP3, theres a big sink hole below the throttle plates on the SP3, and the Q-Jet just didn't seem happy when slammed wide open for the first few seconds.
    My first and only pass this year netted me a 14.1:puzzled: Pass went well, no bog, pulled hard, trans shifted great.
    My AF was 12.0 during the run with the stock 82/92 jetting and timing at 33/34 total
    I waited 2 hours to make one pass at Norwalk, then another half hour in the staging lanes, pretty typical for Friday TNT.
    I swapped in 90 jets in the rear and bumped my timing back to 36 total, haven't been back to the track yet.
    On the AED 850, a lot of non Buick people say "that's way too big" but my AF numbers say different, and the drivability is like fuel injection, VERY responsive/sensitive, absolutely no loading up, I'm happy I went 850 cfm.
    I'm determined to get my 13's back!!!!!
