x2 what Broncobowsher said. I'm doing a 89 (non-roller) from a full size bronco right now. It is pretty cool to have the newer 5.0 upgrades such as the dip stick in the block, newer casting technology, aftermarket parts availible, option to go roller if you choose.
I'm staying flat tappet and sticking on my eddie intake and eddie 500cfm.
