Hey guys, I have a 93 bronco with 351w that leaks like a mofo. It runs great, only 165k miles. I want to go through it and reseal it if its good, hopefully just resurfacing heads, nothing major. I have alot going on and may not get to that for quite some time. I have a line on a 1991 E-250 with a good running 351w. What, if any, differences are there between these engines? Im thinking I can just swap engines to enjoy my bronco until I get time to go through the original engine. Will I run into any issues/differences? Any information is appreciated.
