A-body small block to big block K-frame ?

[Burpin Chunks]

putting 440 in 71 dart, do i need to switch out the k frame or can it be the same, just switch out mounts?

Appears a conversion motor mount kit is required

We used Schumacher mounts to put a 440 on a 1976 slant-6 k-member in a 1970 Dart and everything lined up perfectly.  I would expect the same with LA-to-RB mounts.  Just make sure to follow their directions on how to install.

the later Abody 74-75 K frame with spool monts can also be used but why change the K if the mounts are available ?

We liked the design of the newer k-member, and since we had one as a spare, we decided to use it instead of the the original.

the spool mount was a far better design
