  • 454 Blue Boats RePower

    Scott's Carrera, melted a piston about a year ago. So he looked at his options, and I think we came up with a nice solution. I assembled a little milder engine then he had been running. The last engine was an 11.5 to 1 (at least) 454, that ran really strong. In an effort to give this engine a little longer life span, We are using some different components. Base engine is a 89 4 bolt 454, that has maybe 5000 miles on a bottom end rebuild. we have a .020" overbore 454. stock crank (.010 x .010) I Beam rods with ARP Bolts. I used 3/4 groove main bearings, clevite 77 rod bearings. The rotating assembly all showed signs of recent balance work, So I had the machinist polish the crank, for just a little more oil clearance (.0029" instead of .0025") Went with a pair of 1968 closed chamber big oval port heads (063's) 101 cc. the deck height was off .004" from left side to ride side of the block, so had 1 head surfaced .004" to bring it square. We are running a Crane Cam and springs, sig erson roller rockers, ARP Main and Head Bolts, and a trick modified windage tray and oil pan combo of an offshore boat (14 qts.) Scotts old tunnel ram and 660 holley's. Heres a couple pics.











    Then I went ahead and checked the timing real quick. Sounds ready to rock!
