I'd say you made out like abandit!
Just taking a stab at it, Dana - $200, 440-1 heads and rockers - $4000, 426 Hemi assuming complete non running - $8000, alum hemi heads $3500, stroker cranks $4000, dual head distributor - $500, misc parts - call it an even grand, you total on stuff is $21,200.
I'd say it was a good trade.
