I was wondering if anyone could tell me what size jets I should use with my current setup. I have a 400 steel block modified engine with high 600's cam lift. Brodix 11x aluminum heads with 2.05, 1.60 valves. Torquer 2 intake with a holly 4412 two barrel. What size jets would be recommended?

im in the south at sea level, 76 on super, 78 on 110, what my engine builder says anyway
There is really no way anyone can give you an answer for this. It depends on carb modifications, cam specs, head work, etc. You need to pick a starting point that you think will be a tad rich and get started reading plugs to tune it in.
