I want to know is the combination of a '78 Chevy 350 engine mated to Chevy 400 transmission a good combination for drivability, gas mileage, etc.? It is going into a '50 Dodge Wayfarer.

It will work just fine. A BETTER combo would be a 700R4 behind your 350. If you are buying a trans this is what I would do even though it costs a bit more... Both mileage AND performance will be better, especially if you have some steep gears out back.

The 700R is more readily available than the th350 or th400 trans would be for near the same $cost$. Just MAKE sure you get a good trans to Begin with. Always better to get one you know came out of a Donner so you can CK out the trans before you install it..Don't buy a pig in a poke so to speak??

Like said, the 700R is probably your best bet.

About the Turbo400, it takes more horsepower from your engine to spin one of these than a Turbo350 or a 700R.............thus worse mileage.

As a Moderator here , I would like to
WELCOME YOU here ...

A Turbo 400 does take a small amount more of horsepower to turn ... thus it is considered less fuel efficient. But it is way more durable. I suggest finding a 2004R or a 700R4 ... for the Overdrive feature.

Again ... WELCOME ...

the 400 is virtually bullitt proof but the 700r4 has overdrive with gas the way it is go for the 700r4
