Engine Quest Dodge Magnum Heads New Zealand castings.

My plan is 10.5-1 compression and the Comp Cams big Mutha Thumpr hyd roller cam. Duration intake 243@50, Exhaust 257@50, lift intake .533, exhaust .519. LSA 107. with 1.6 roller rockers = intake .568 and exhaust .553. KB flat top pistons, a tunnel ram manifold and either 2 x 450cfm - 2 x 600cfm carbs.

Run from the 450 carbs. I's think at least two 650 DP's would be the best. You can go to 750's if you are willing to use annular boosters.
