Which Clutch should i go with

its not that the hipo used a special bell or clutch,,, all 273 2bbl or 4bbl used the 9 1/2 inch clutch,,

you can upgrade to a 10 1/2 inch clutch,and then havea wider choice of clutches to choose from by using a later model bell housing or a scatter shield,,

all small block bell housing will bolt up to your 273 and your 66 tranny will bolt to any mopar smal block bell housing or after market scatter shield,,

im sure you can find a bell housing on this site if you loook around
