Re: 67 ranchero z code
I have two '67 Rancheros. One is a C code converted to 390 suspension and 9" powered by a 408W. The other is an H code 390 2bbl that will be getting the 289 and C4 from #1. I am leaving the 9" rear in with a 3.50 axle ratio. These trucks are SO popular ( especially in rust free California condition) that I don't think the "correct" engine makes a difference resale wise. You could certainly dump allot of money doing an NOS parts restoration but would IMHO , never recover costs involved.
