[QUOTE="AustinSN, post: 15967819, member: 159453"] Kinda stupid. First, we don't know if the heads are going to be reworked on this engine. The 240hp bump from the roush kit is on an engine with a smaller displacement, maybe smaller heads, different cams and it likely doesn't meet Ford's reliability requirements. The CR is a big change too, general rule of thumb is 4% per point of CR. So if the aluminator now is 12:1 and the new engine is 10:1, it's 8% low. Also, the aluminator has no emissions it needs to meet. Also, I really, really doubt this engine will turn 8k RPM like the aluminator. Way too many variables. Not to mention that video was too long to say "well the 5.0 picked up 240hp, so the non-street legal CPC 5.2 should pick up the same." [/QUOTE]
