    I think we should start a thread on all of the Boosted Buicks. There are not a lot of us yet but we are seeing more all the time. A central location with what we have done could be helpful to all.

    Listed so far
    turbo 455-2
    supercharged 455-7 (2 race only, the others street driven)
    turbo 350-2
    671 nitro blown nailhead! -1 so way cool I can't stand it.
    supercharged 370-1
    supercharged 340 -1
    supercharged 215-1
    turbo 401-1 single turbo rear mount
    Added a table in word to keep track. Let me know what changes are needed.

    Dougs BBB procharged Skylark

    Guess I should be first since I started the thread.

    70 Skylark
    455 forged pistons, Cometic gaskets with ARP studs
    9.5:1 compression
    TA 413 Cam
    SP-1 intake, ported stage 1 irons
    QuickFuel 650 BAN
    Postons girdled oil pan

    Procharger D-1 home made brackets
    6 inch crank pulley 4 inch blower pulley 5PSI@5000 rpm

    SX fuel pump -8AN feed -10 AN return RobbMC regulator

    32 degrees total timing with -1.5 degrees per pound of boost.

    I do not think the TA 413 is the best cam for blower. Will be working on that. What else do we want to know?

    ok I will do these one at a time.

    first one
    535 cu. 8.00 to 1 compression
    mopar crank custom fit
    r&r aluminum rods
    wiscoe custom pistons
    stage three heads done by FLM
    sp2 intake
    cam is a FLM custom blower cam flat tappet from compition components
    ta front cover
    rollmaster timing chain
    quick fuel e-85 carb 850cfm
    f1-r pro-charger

    we have run this combo on 93 octane as well as the e-85. the e-85 combo is still being snuck up on since we never dynoed with it on the motor.
    this combo is in a tube chassis regal with the drive on board and half a fuel tank worth of fuel it scaled 2650lbs.
    we have run 8.24 @ 164 on 93 octane with 12lbs of boost and so far we have run 8.30 @ 163 with a really safe and soft tune up in it we had hoped to turn it up in Osceola but broke the tranny when we started turning up the power. We should be ready to let it rip in BG

    Ok number two.

    this is a 464 cu. stock block 8.5 to 1
    stock crank widen for Chevy rods
    R&R aluminum rods
    wiscoe pro tru dished pistons
    custom blower FLM solid flat tappet cam from compition components
    Pro_-form front cover
    rollmaster timing
    oiling lifters
    stage 4 heads with very little work done to them
    Indy mopar intake
    csu gas carb 850cfm
    custom air to air intercooler
    scavenger oiling system
    f-2 pro-charger with 16 lbs of boost

    the car is a stock suspension 25.5 certed 72 stage one car it weighs in at 3740LBS with the driver. This car has run 8.80 @154.50 still working on getting the sixty foots settled down. I run mt drag radials on this car I think with a little work we can maybe get some 8.70 out of it at BG. this short block has all the stuff done to it but is all used parts except the cam and lifters. Not real sure how long it will last but with out a good block I hate to spend very much building anything right now.

    post the small block combo later

    can you guys describe what you did to adapt your supercharger? Like info on your brackets, oil feed line, crank pulley, relocated ps, etc. I am planning to go boosted eventually (just have to get other things in line first like the drive train) but I already have a Novi 2000 that I plan to use. I'd like to make some of these parts myself for fun.

    Ps..if this doesn't go here let me know and I'll start another thread.

    What else are you running with that? carb, amount of boost, etc

    How does yours work with the 413?
  18. Staged 1

    Staged 1 Buick 455 under pressure

    Doug, It is a holly 850 blow through from what I have been told. I bought the car with all the parts installed. Runs good. May be a bit too big of a carb from what I have read. Not 100% on the 413. Idles awesome(racecar like) and seems to run good on the street. Not sure about full boost yet. Have not truely run it hard yet. 4"pulley. Maybe 10lbs? Still learning:TU:
