Frank’s immaculate Mustang concourse car had the Dandy Engines treatment performed to its Boss 302 heads. We port filled the intake runners to get them down to 190cc. Running a factory duel plane intake manifold the engine makes a healthy 370 HP and 340 ft lb. Considering the cam has only 218 @ .050 it’s a real stump puller.
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.
