W2 Heads on 1996 Magnum 360 Block

A Long snout is a must have with a mechanical fuel pump.
If your going to use an intank fuel pump, no worries.
Hughesengines makes an adapter part for short snout cams to use a fuel pump eccentric.
IIRC, some places said long snout cams do not fit under some (later year) Magnum from covers.
