I guess what I am looking for, is the least amount of modifications.

Randy Go with an O-320 as the O-290 engine is an older design which does not use hydraulic lifters, weights about the same, puts out less power and is much less desirable. You can also use a 180 hp O-360 parallel valve engine which will fit the -9A.
