MAST SINGLE PLANE
The Mast intake was an impressive unit, with twopiece construction that allowed full CNC porting. The porting looked so nice that we hated to run it, but run it we did. Like the previous intakes, the Mast was run with the same Holley 950 Ultra XP carburetor. The carburetor was jetted to provide the optimal air/fuel ratio to maximize power production, and we employed timing sweeps to do likewise. Though we ran it in carbureted from, the Mast intake was also configured for EFI use. We simply plugged the holes with injectors and fed the combination with the Holley carburetor. Run on the 415 stroker, the Mast intake produced peak numbers of 650 hp at 6,700 rpm and 555 lb-ft of torque at 5,000 rpm.
