Everything about the last Studebakers was very reasonable.
Good IFS
Good chassis
Good ventilation
Good brakes
To the stalwart reliablity of the old 1939 six was added another 2000 rpm and more miles per gallon, and genuinely good acceleration with the extra 22hp and making 20.3 second quarter miles and 0-60's in 16 secs was far better than the unmodified 170 flattie. Prblem is, all the gear is for the flatties, they have 140 hp versions which really honk.
Your OHV options are great, though.
