This 426ci Hemi V8 engine was acquired a decade ago and reportedly rebuilt by Arizonan drag racer John Aleman “SheepHerder”. The block retains its standard bore size, factory valvetrain, connecting rods, pistons, and a 10. 25:1 compression ratio, complemented by an ISKY Racing Cams roller tappet camshaft and dual carburetors with Edelbrock decals.
