Looking for Original Block

I wish he would. His whole family is telling him to do the right thing, it is in a 1978 Roadrunner of all things and offered a replacement block to help.

I had to double check my block I'm building because it sounded close. Unfortunately, it was close, 1B409470, but not correct. I hope you are able to find out if the one he has is correct and a deal worked out, or another lead comes along that leads you to your block. Good luck.
