So I take it he doesn't want much power? From a 360 to a 302?? 
Why would he do that? Yeah the 302 is a good motor but not as strong as the 360/390/351. And with a 351 you got windsor and cleveland to choose from. There are a lot more options rather than downsizing.
Or he could go 427,428, 429 or 460. There are tons of 302's out there and they will make, in m experience, more power than a 360. The windsor is an option too, but there aren't very many of them out there any more. A block is getting harder and harder to find. Just because you are dropping C.I.'s doesn't necessarily mean you are losing power. A good swap for him to do would be put a 302 Fuel Injected H.O. out of a late 80's mustang into it.
