Another very mild 440 build.....
Along the same lines as the 7.5:1 build Jim LaRoy tested several years ago...... but this one steps up the CR a bit, and gets ootb Stealth heads instead of the factory pieces.
It’s a .030 440 with cast pistons down the hole .110”.
Small Summit cam(214/224-112), stock rockers and pushrods.
Stealth heads that have had the guides checked and the seats bumped with a stone. Zero porting.
Using all the hardware that came on the heads.
Stock 440 intake(casting number 3512501), 1” open carb spacer and an old 3310(750vs)carb, Hooker 1-7/8” headers.
Mopar ignition kit, timing 10* at idle/38* total.
CR works out to 8.7:1.
I’d say it would easily make solidly over 400hp with a little more cam and an intake manifold upgrade.
Although....... none of that will be happening on this motor.
In the car, it won’t have the headers either.
