Well....finally engine in and headers on. After putting the dbl. hump v8 trans crossmember it slid forward and the engine mounts fit great. Still had some space in the elongated holes so I would say there is a difference in trans mounts (visually between the two you can see more forward room between them). Headers went in actually really nice. Alittle tight by the drivers engine mount and oil pan but I would say superb! I would definitely suggest Hooker headers to everyone. The weekend has ended on a happy note and no to tackle wiring the ecm this week. thank you all for your help.
