Just acquired a 2001 Baja Outlaw with a 502ci engine,, I’m looking at the worst of the worst situation. Engine replacement. The 502 is having major engine issues, What engines would be a “cheaper” alternative to replace the 502?? Any big block like a 454 or 496? Can I get a shortblock 454 and swap entire top end heads, cam, intake from the 502 and put on the 454?? Just weighing my options. Thanks.
