[FFR428]

Walk away it's not a 427. Those two bolts you see are where the blocks were mounted at the factory for the machine work to be done. Sounds like he stuck a couple of bolts in there to simulate crossbolts. You would see three on each side as stated above. There will be another hang in there. It might be a 428 or 390 or who knows but not a 427 thats for sure with what you observed. G.
