Bostick built!
Pump gas friendly 489 for a 21' family cruiser. The requirements were: It had to run on pump gas (even the crap they have at the dock), had to work with wet exhaust system, needed to make all it's beans by 6k rpm, and needed to be driver friendly to pull skiers and tubes behind a very heavy 21' open bow. No problem...here's what we put together... Gm production 4 bolt block completely machined and worked by BRE, 10:1 SRP +.030 pistons, Edelbrock small Victor 300 heads reworked by BRE with a "little" port detailing, machined down to 115cc's, guides honed for marine application, and a nice 3 angle valve job, 6.385 H beam rods w/ ARP2000 bolts, Scat 4.250 steel crankshaft, Schneider custom hydraulic roller (low 230's intake, low 240's exhaust and .615 lift), Isky hydraulic roller lifters, Comp 1.7 stainless rockers. Built for a family cruiser that should get up and move when needed. Made a best of 648hp@6000 and 632tq@4700... with a power band flat as a pancake... hitting just over 600hp@5000 rpm. Will idle at 800-850ish, which is very nice for I/O applications... but still making decent power for a jet boat friendly application.
Totally awesome guy to deal with! Best experience when my hard earned cash was on the line. Defiantly would recommend and will be going back for my pump work!
