74 to 65 Drivetrain Swap!

Valkman said
I've been doing searches on this forum and there's too much to information! And my brain is only so big! So I need some help!

I have 65 Barracuda 273 auto. It has a 318 with later model (linkage) 904 trans and a 7¼ rear end with a large bolt pattern. I don’t have much history about this car so I don’t know what all this came out of.

I also have a donor car. It is 74 v8 Duster column shift. I want swap out the good running 340 attached to a 904 trans along with an 8¼ Sure Grip rear end that’s in it.

Can some of you that have done a swap like this tell of anything special I’ll need?

Also how hard is to pull the engine and trans together?

And please no post about needing a stronger drivetrain, I’m on a budget and this going to street driven car so I’m OK with what it is for now

I did this swap in '72. Engine, bell-housing, tranny, driveshaft and 8.75" rear from a '71 Demon donor car into a '64 Valiant 2-door sedan.

The left fromt motor mount was different, but I made the early mount work; can't remember how.

I used EVERYTHING (it was a 4-speed car and my '64 V8 Valiant was 3-speed manual.)

I could NOT get the engine to drop into place with the 340 manifolds on the engine; they hit the inner fender panels on both sides. I put on a set of cheap fenderwell (Hedman) headers.

The driveshaft worked without cutting.

The rear end bolted into place with no modifications (8.75")

The bottom radiator hose conection was on the wrong side of the radiator, so I just ran a long hose and some 90-degree bends over to the other side.

The speedometer cable had to be spliced (it worked!) and the oil pressure gauge had the wrong kind of sender.

Hope this helps!!!
FUN CAR!!! :)
