ok heres what i am planing. A long block 454 kit from NAPA, rebuilt t-400, np-205, shafts, 6 inch lift, tires, rims, d44 front, 14b ff rear. the whole nine. and it's going into what currently has a 305, shot 700-r4, 208, and 10 bolts. 1) any specific years i should look for or look out for when ordering the block and tranny? 2) does anyone have any idea the internal mods i need to have done to the 400 for some bullet proof performance behind the BBC? 3) what do i need for the t-400 to 205 switch? there will be more questions along the way so thanks in advance.
