I am getting ready to re-build a 67 430 with big port heads, but before I do, I wanted to send a last request for a correct 67 date coded NR 400 engine, short or long block. I have a 67 gs400 vert that is missing the 400 and would love to put the correct engine in. I am willing to either pay or swap the 430. Let me know what you got. I also have a complete 67 Riv that the 430 is coming out of that I am parting as well as a 340 currently in the gs. I can swap any of these parts. Let me know what you have and what you want.
