NJBB,
Cb is only partially correct as the paperwork you have spells out what needs to be done to pass the initial safety inspection and get a letter of determination from the DMV in regards to emissions controls on your car. Yes, you can use whatever engine you want in your car, but a vintage block will get you through the initial safety inspection far easier than a late model block. Why is this so, because with a vintage block they are not going to be looking for emissions controls, while with a late model block you are required by the current regulations to have any and all emissions controls for the year of the engine (this is to pass the initial safety inspection process). If you think the inspectors will not check the casting numbers on the block, beware that the last BB ERA I trailed to the Morristown office was looked over from stem to stern inside, outside and underneath. Through the windows we observed the inspection team with flashlights and inspection mirrors looking for and documenting the block casting number for their records. To put it into the proper perspective, this was a turn key build from ERA. Only after you have passed the initial safety inspection (you do know you need side pipe covers, right?) gotten all of your paperwork in order and sent it down to Trenton (or you can go to the special titles divisional office on State Street in Trenton) for your title to be issued, you can then use the "collectors registration" option to register your car.

Again I do hope you find these smaller clarification points useful.
