    Looking at building a spare for my K5 where's what i have so far....

    Stock 454 block
    Stock crank & Rods
    Wolverine Cam Lift is .595/.621, duration is 320/330
    990's heads 2.25/1.88 ported
    Hurricane intake
    Looking @ either the H581CP60 or H581CP100 pistons which are a 30cc dome

    So i was thinking w/
    .060 pistons i'd do .010 deck clearance w/ a .039 gasket which would get 10.5:1
    .100 pistons id do .010 deck and a .039 gasket and get 10.6:1

    Or should I look @ more compression...
    Setup is a TH350/NP205 w/ 3800 stall & 5.13 gears

    Any input to how good this combo might?
