Slant six to small block 340-360 engine won't fit.

Thanks for the help, I really appreciate it bro. And everyone else who confirmed your assessments. The mounts look like they're gonna line up ok. At least I hope so. It's a Transdapt 6 to 340-360 engine mount kit. I matched the pics to the instruction pictures, that came w/kit. But I won't really know until I can set it all the way down. Heh, heh. Now I can't find a 360 oil pan for a 1970 car. It looks like 1972 and up is what's available on-line. And that makes sense about the truck pan. That motor came out of a 1949 international SUV -type truck thing. It had all kinds of weird stuff bolted to it. If you know where i can buy a 360 car pan that fits a 1970 duster - I would be grateful. Grateful many times over! heh,heh.
You won't find a "1970 360 car oil pan" because there were no 360's in '70. Just get a car oil pan AND pick up tube, and you'll be ok.
Jegs, Summit, ebay, they all sell them new or get a used one from here or marketplace or wherever.
