most cranking amps in the smallest size which will fit your application, i like the sealed gel cell batteries myself as they can be mounted on thier side and even upside down.
For the 57 after running a old one from the scrap yard for 5 years I took a tape and measured the old one and bought one the same size. the one in my ranger is from a buddy that was scrapping out his Hyundai fit with zipcut. for three seasons and a tuned car with a proper charging system just about anything should be good enough . crap the free hyundai fired my truck at -30 last week

seriously any of the name brands should fit the bill. if your charging system is proper and i like to take them out for the winter if the car/truck is stored un-heated. in the spring put a battery tender on it and give it a cleaning you are good to go. anything 750cca should be lots.
i had up till about 2 years ago a canadian tire eliminator battery that i bought for my tow truck, it was in the truck for 7 years, i then replaced it and put it in my van and ran it for almost 2 more years, so i almost got 9 years out of a battery and it only really died cause i left my interior light on one night and killed it.
A little FYI on car batteries;
The GM battery plant in Oshawa (RIP) obviously built the batteries that went into the cars they built there, but few know that they also built the batteries for Sears, some Canadian Tire and Toyota or Honda (forgot which) as well as a few other unknown brands. They were all built on the same line, using the same process and the same cases. The only thing that was different between the brands was number and thickness of plates.It was one of the best battery manufacturing plants, but politics killed it unfortunately.
