1000+ HP Holden 308

After a long slow build we ran this engine up on the dyno recently. It’s 318ci after the factory crank was stroked to better suit the Chev pistons & rod configuration.

The 76mm s400 turbo is blowing thru a water to air intercooler, custom Holley carb and Harrop manifold. Other specs are: Forged pistons, H beam rods, custom flat tappet cam, ICE ignition. Block and heads are factory cast iron. End result was 1020 HP and 1070 ft lb with a concervative tune and 25 psi boost.

It’s new home will be Tony’s HQ featured in an earlier post.
