    hi guys,
    I'm new in this forum
    I will start my project soon on my caprice 86 (street-strip) +1100 (((on the wheel))))
    in the beginning, I'm really confused between going with (twin-turbo 540 big Block) or single LS 6.0
    I want to go with big Block but most of the people always against me and they told me (big Block is too heavy for your car ... you will not get what you want ), etc..........
    so I do a lot of research about that
    And to be honest, I saw both of the engines (boosted).. and they were great
    but with big Block always have perfect Torque and really good numbers even with low boost
    after a couple of months, I sew A lot of Projects with LS so I Change my mind
    because I think is not easy to find all the custom part for Bbc like headers and etc..  
    after that, I decided to go with LS
    so I chose these parts

    LS 6.0 forged bottom end
    225 AFR cylinder head
    Holley sniper intake
    single-precision turbo 88
    +1100 on the wheel

    But before a couple of days, I so Richard Holdener test a new engine from Blueprint Engines
    540 bbc Compression ratio

    exactly what I'm looking for
    Long block and ready for the boost
    8.5 Compression ratio
    Richard Holdener test this engine with twin S475 on 15.8 PSI
    1300 HP on dyno ( i think it will be around 1000 one the wheel )
    and I know I can boost this engine more ... easily because the low compression
    After I saw this test on the engine I decided to go with a big block ((right now))
    I know it's not easy to find the part for Bbc but I think it's worth

    so, guys, I need your opinion if you were me, what would your choice and why?

    and I hope it will be a nice discussion

    thanks so many guys
