just as the subject says, i am looking to purchase this combo and dont want to get ripped? anyone buy anything similar?

I just bought another 420 today, $100.00, with a SBC cast iron bell housing. The first 2 I found where $40.00 and $50.00 dollars, but this last one has a reverse light switch that was only found in a 67, plus the bell housing, don't really feel like I got hurt on any of these. I'm not sure about the 221.
Hope this helps, Andy

the sm420 with the timken 221 tcase is awesome!.... the case only has like 2.2:1 ? or only 2 to 1 gearing, but has an option of 2 rear driveshaft outputs.... and u can use the low one on the rear and SERIOUSLY reduce your rear dshaft angle!

they used to use this combo in dumptrucks---!

they are pretty rare still found together... but i wouldnt value it anymore than a sm465 to np205 case combo
