Dan,
No offense taken at all. Just trying to help us all "figure it out.." My
"limited" brain capacity is just suprised that an alum block would only save
~35lbs.. I was trying to extrapolate it based off of my limited history with
the units in my garage..
All I know is I have a gorgeous 302 block painted Forb Blue, that basically
matches the body color of my B, and I am going crazy not being able to get
it installed!! :-)
If you could scan in thos epictures it would be much appreciated!!
Larry
