Which carb to use?

[HeinzK5]

I have a 350 in a early 80s Blazer automatic 4X4. The motor has headers, aftermarket dual plane intake, a comp cam (12-235-2) Duration @ .050 I210. & E218. lift I.447 & E .462 Lobe centerline 111. Flat top pistons and smog heads w/76cc
i have this carb 17084227 with electric choke but has rear pull off
I got this carb at swap meet today cheep 17080212 it has the front pull off.
so what  one would be better to use?

Both would be fine.  I like the front pull-off models better, as they are much easier to set-up than the rear only models.....Cliff
