People have been putting chevy's into foooorrrdddsss for a while now, why not turn it around. Just get thick skin cause your gonna get some ribbin, or just build a wicked fast ford engine and shut them that way. A buddy put a 360 chrysler in a chevelle so there have been stranger things done.
Seriously that little 289 is compact enough to fit without many clearance problems, paint it orange and most people won't know the difference.LOL
