1471 blown pump gas 548...

Yes, it's a marine build but blower motors are always entertaining...

548ci, 4.53 bore x 4.25 stroke
Dart Sportsman Gen6 block
Scat standard weight crank, Scat 6.385 rods
JE dished blower pistons, 8.5:1 cr
Romac blower balancer
Canfield 355 heads (the last pair ever made) with CNC chamber and ported with Ferrea Competition intakes and SuperAlloy exhaust, Isky RAD Tool Room springs and Ti retainers.
T&D shaft rockers, rockers shot peened with spring oilers for endurance.
Straub custom solid roller, GS ultra Pro lifters and Smith Brothers 7/16 x .120 wall single taper pushrods.
Intake is from the Blower Shop and is ported to match the heads and a Superchiller that got o-ring'd on both sides.
Littlefield 1471 blower for pump gas and a pair of 1150 Holleys prepped by AED with their Teflon coating for the marine environment.
Pan is a big Stef's full sump, full kick out with a detailed Melling HV pump. Block also was set up with piston oilers from BLP.
Crank trigger is from Aerospace Eng. because they were the only ones I could find with a flying magnet wheel with the 6 bolt blower pattern.
Blower is 9% overdriven and showed 10.5# of boost and we ran 32* timing.
Best power today was 1147 @ 7000 still climbing and 989 lbs/ft @ 5000 on 93 oct BP premium pump gas.
