Intake manifold options for a Magnum 5.9/360

I have a stroked version of y our motor and use an M1. These things have great torque, also when not stroked, and if you’re running a 4.10 gear maybe you’d want to consider the m1 also? Add a little cam so you don’t run out up top like you have been and you’ll have a great overall package. M2’s are available used from time to time too.

The cam I use us a 108cl 501/513 lift with 230/234. It’s fairly stout but kinda peaks around the 5500 mark anyway and I notice no performance loss using the single plane.

Good luck on this endeavour and your final choices.
