Ford Racing 427 Alum block specs

Has anyone seen the actual specs on these crate engines? I've seen differing comp ratios (10.5:1 vs. 11:1) on different sites. There is plenty of info on the Iron block versions; however, the real data for the Alum blocks is hard to find. I have seen anywhere from 570 to 600 HP and 527 to 553 Ft Lbs???

Does anyone know someone with this set up? Thanks.

Gary,
The reason you are seeing differences is that Ford Racing announced the engine one way and built a number of them (mostly prototypes like the one in your car) and then recently they changed some suppliers and reworked the specs. and numbers. It had something to do with the head manufacturer they were using originally went under, I don't know who it was that's as much info as I was given.

Thx-I drove the car this week in Fla. Seemed like it ran well...scary fast but I've only driven one of these so hard to have an opinion. Def a whole different feel than my other hotrods in the past. I will see if BDR can get me the specs for the engine in my car, I would think they would have them from Ford?

Thx again for the input.
