ATK 5.9 Magnum crate motor horse power

Johnny - OK, great. Thanks for the clarification on the damper. Yes, that is a plus in the value equation (which should be in the picture as you mentioned). And perhaps "pricey" was the wrong word. I think it's an unbelievable value and well worth the money, I only meant that in absolute terms $7,800 is a decent chunk out of the bank account (pricey in total cost, not relative value). But for what you get it looks impossible to duplicate anywhere else. Amazing overall package.

As for the OE iron Magnum heads, it's not that they are cracked when you build them or that they crack on the dyno or any time in your possession. I know you guys would never build or ship anything in that condition. But over time they have a very high propensity to crack (and maybe after the warranty period). If I'm spending crate engine money, I don't want to take a chance on such a head.

Neither here nor there, the 4085CTC is the clear winner in my book. Just need to save up for an extra year or raid the kids college fund...
