Aluminum 5.2L Magnum Block - CL

Dont know if these are the same engines or not but in the mid-90s Chrysler made a handfull, four sounds about right, of magnum engines by pouring aluminum in the production molds at the urging of Bob Lutz. There was no addititional engineering work was done other than to make sure the heads had decent flow with valve seat inserts. As the Magnum development engineer I ran these on a performance dyno and they made exactly the same output - this is NOT what my bosses wanted to hear. There were no problems what so ever which just means that the production cast iron version was way way over- designed. The bottom line was the only reason to do this was weight saving and as someone said it was just too expensive.

I would have LOVED to get one of these but you know... That wouldn't have been right and these prototypes should have been melted down.

A bit more realistic was the "Max" 5.9 with a little bit higher compression, 2.02"'intake valves and a normal intake ( a $55 cost saving too) which actually had the same or better output than the 5.7 Hemi but that's another story.
