I had Manley h beams when I sent my hemi out to be redone.Builder made a mistake on the replacement 4.5 stroke crank and said he would replace the rod due to me having chevy ends and the Callies crank he bought had Chrysler ends.After 5 years I had to freshen it again and found Eagle rods.Checked and they are good to 1500 HP.
Buy the best your wallet will allow!

HEMI-ITIS has no cure.
My condition is fully BLOWN!!
