Re-read my post I was still thinking and editing.
$424? then work on it? and parts? and put it back together? That's maybe $1500-2500 or more. There is at least one running motor on the 6066 site. $200 in Texas. Those guys are honest to buy from. I was going to put in a Chevy in my 1960 GMC but I found the 305E I mentioned, right in my town, and decided dropping it in was much easier. Why don't you hang loose for a few weeks unless you are in a hurry or are rich. If he bores it you will have to find oversized pistons or rings and all that, gets hairy. If you are not a purest, go Chevy! You can buy a GM waranteed crate motor pretty reasonable now-a-days. It does take some fab work for that frame.
