Newbie 360 info

Machine shop messed up and used a magnum 360 block instead of the La. They bought me a set of EQ heads since the J's would no longer work. Will I have any additional power gains with it being a magnum block and the EQ heads with all the same parts listed below on the build.



I'm having a la 360 getting put together right now for my 74 dart swinger. I'm wanting to know what power level and quarter mile time you guys would guess for it here in colorado.
