I am picking up an 89 Dodge van with a 318. It is an automatic and EFI.

I am gathering pieces for a budget daily driver type 318 for my A body. Most likely carburetor equipped.

Regarding this 318, a couple of questions:

What head castings should they be?
Compression ratio-Rated?
Roller cam yes or no?

Is the transmission is a 904 with a low-gear set and lock-up?

Basically I would like to clean it up and throw a carb, distributor and use it as is. I am primarily interested in MPG with performance being secondary to mileage although both would be good.

Thanks people.
