Putting a newer engine or newer transmission in the older truck will require fabricating, since the 292 was not around in 1960. The easiest thing to do is rebuild a good 235 and add a period correct transmission. The original truck 4 speed SM 420 will bolt right up to your bellhousing. Only mod would be a longer driveshaft. The simplist automatic conversion would be to a 1962 and older powerglide which bolts right up to the 235.I would go to a 3.55 ring and pinion change (available in aftermarket)to the original rear axle. Newer 3.08 axle change would be alot of work and too high for a small 235.
