Will a 700r4 from a 350 bolt upto a 4.3?

Just wondering if a 700r4 tranny from a 350 will be able to bolt up to a 4.3 motor? Is there a difference in vortec and non-vortec 4.3s? (as far as bolting up trannys goes)

a 4.3 is a 350 with 2 cyliders cut off the bolt patterns should be the same. cause they are both 90 degree block. So it should work.

Are you sure the 700 from the "Vortech" isn't a 4L60E Electronic shifted one?
The 96up Vortech(4.3,5.0,5.7, and 7.4L) use a Central fuel injection unit instead of the previous TBI injection. The 4.3 uses 1 injector and 6 poppet valves, the v-8's use 2 injectors and 8 poppet valves. Thats the difference, along with revised cylinder heads to match the intakes.

i SURE it will bolt ,the difference that you speak of are differences in the intake and the heads, the block is the same on the 4.3 and the 350. the only thing thats different is the amount of holes that are bored into it.
