    I supply a mini-starter to solve that clearance issue. Then when your looking for MORE POWER without a cam change my "Adjustable Roller Tip Rocker Arms". On stock applications they are worth about 40-50HP+or-. You can read about others comments & results with them on V8buick.com Go to "search" & type in "toms roller rockers". I'm on my 2nd. run of 50 sets now & should be seeing them in a few weeks.

    Yes, a 401 is definitely overkill in a 29 sports coupe.










    And that's exactly why you should do it.

    There is no such thing as overkill when you build a hotrod...

    This thread seems to be place where all nailhead-equipped-hotrod -builders gather together... so I'll have to enroll also!
    I'll be using this ST-400 trans which started it's life in '65 Buick.
    Engine is 364 ('57), so it is easy to bolt behind it, but how about flexplate, what kind of work I'll have with that? I mean; dynaflow and this more new st-400 propably have different kind of flexplates? Or do they?
    Help? Anyone? Zman?

    Yep! Exactly right. If I was doin' that '29, I'd simply set it on a pair of Deuce rails. (3" longer, no firewall butchery, you get to keep your legs...)

    Thet there Buick is longer than a story...

    Go for it!! A oversize engine is like a big dick!! Use what ya need!!If the ladies complain don't put it in all the way!Simple solution.Use the gas peddle as much as it takes to beat the other car
    Guns the same way" better to have a gun & not need it then to need a gun & not have one"

    if you go with a stick. i'm interested in the flywheel. (909)562-0515 perk_d@hotmail.com
     
  8. I'm guessing the bigger Nailheads pull very much like the later BBB's
    (430 & up) considering that both versions are quite torquey on the low end.

    To that end, imo, you don't need a switch-pitch in a light car with such a torquey engine.
    Nor do you need a very high stall converter.

    My 32 roadster as a 2400 rpm stall B&M converter and it's been pretty good for all round use.
    Thinking too of going down to 2200 rpm for the 31 on 32 rails roadster.

    Build the engine accordingly, keep the CR down.
    The BBB in the 32 is 9/1 CR and I run 87 octane summer and winter.
    Timing is the usually recommended for BBB"s 32 degree's all-in.

    The 32 with 400 HP or so is easy to drive.
    Be calm, roll the throttle on, shift when it starts pulling hard and if it spins a bit in 2nd, shift again.

    Pic's.

    Still hazing the tires at 85.

    If you want a five speed, look at the Tremec TKO 500 or 600.
