Need Help on Magnum 360/380 hp Crate Motor Tech Info

The reason I asked was because I'm currently talking to a guy with heads, cam, and 3000 stall from his build they wasn't fast enough for him and at a great price fer me.
Thanks




I thought that was a flat tappet cam issue not a roller cam issue???
They can be... I "inherited" a freebie 360 Mag, it had three flat cam lobes, It was using Delo 15-40 , with an oil additive... It does happen....
