I wasn't sure if there was a trend on a certain block that was superior than the other because of casting or roller or __________ (fill in the blank). Thanks all.
I haven't heard of a bad casting..
Some like the roller lifters of the magnum and some like the shaft rockers of the LA .. I believe the 89-91 transition block has both. The running consensus is any of them do well but the HP limit for any stock block is around 600... After that most would be looking for a after market block...
