5.2 Magnum Build

Change the heads, for 2 reasons...195k so the guides n exhaust are toast and 2 they don't flow all that well on today's terms.

Carb and headers. Done. The cams are decent in the 318 ,like .432 or so on the intake and .441 exhaust, the rt cam is a .436/.444 lobe. I have one and measured it to know the diff. A lot of the power is in being able to tune it ,cut out the computer in other words... bit if you really want 4oo hp then something in the .490-.513 lift and [email protected] and pick your lsa & cl for the range and idle quality
