well i do have a cam that can only be fitted with the bearing towers cut in half and bolted back on to get the lobes through, nah N/A would be way to undrivable. i have a cossie bottom end so should handle a turbo/supercharger better than sierra bottom end. but even then ill need to sus a dam good port job. maybe section a spare 2L head and learn how far it can be ported and where.
