The slant or the 318

The swap mounts for the Duster that will still use the /6 K-frame are about $40 dollars or so from Trans Dapt.

The /6 trans will not bolt up to a small block. You'll need a small block trans. Then converter, shortened driveshaft if you change trannys from a 904 to a 727, shifter, linkage, the list goes on.

I have a couple of questions here on this:
1. Where is that that you can get the V8 swap mounts for 40bucks? (can you just google Trans Dapt?) cause I did and didn't find anything there except S10 engine swap

2. Why can't you just buy a bell housing clutch, pressure plate, and throwout bearing, and use the same trans?

Why I ask is I did this very thing to a 74 Duster back in early 80's and had know problem with it and was quite a bit of fun. No I am not arguing just asking because you probably know way much more than I do about this sort of thing.
