is a intake off a 460 able to be put onto a 400 mod. also does a stall converter for a C6 trans able to go on a E4OD trans.

 

no for both

 

you might double check the converter question. is say that because the C6/E4OD flexplate are the same. the intake wont work.

 

the c6 has a single input shaft, the e4od has a dual shaft for od and such.
Easiest thing to do to find out for sure about the tq converter, is call a transmission shop. A little bit of their time on the phone is all it takes to know for sure.
351m and 400m intakes are the same, 377-429-460 are the same.
Its the "M" distributor that interchanges with the 460 not the intake.
