sb400 or 383

[SamMargritz00]

Well after seeing my old toy (my 82 chevy) drive by a week ago I realized I miss rodding around in the water, snow, etc. Since my Dodge cummins is only 2wd and my other blazer is a "show" rig that only sees sand or paveent, Im wanting another 4x4 to play with. ive had 350's which are easily found for sale and have 383 stroker in the 1 ton, but what about the sb400? My dad said he had one when he was in highschool and stated that its the best engine hes ever had. So my question is should I try to find a blaze/jimmy with the 400 or would it be wasted time and just one with a 350 or 383.
