Hot Rods Battery question..... cranking amps.

I'm looking for a different battery option for my '32 5 window. The battery box in the floor needed to be eliminated to make room for exhaust. The car has a rumble seat so a conventional trunk mount isn't an option. I was looking at airplane batteries and found this dry cell battery. It looks interesting and I like the compact size. It can be mounted vertically as well. This option is 545 cranking amps. Would this suffice for a 283 with probably 9.5:1 to 10:1 compression?

A battery box is available as well for pretty reasonable.



Thanks in advance.

I have an Odyssey PC680 under the dash which is similar to the PC545 but with a few more CAs.
It's fine with a 9.5:1 compression ratio, and I only have to replace it about every 7 years with no maintenance other than fully charging it in the spring. I am running a high-torque Denso style mini-starter that draws less amps however.

As a precaution when starting the engine after it has been sitting for a week or more, I attach a jump box to the Odyssey so that it won't wear down with extensive cranking.

Thanks.
I noticed the PC-680 after I started the thread. One's on it's way north. Nice thing about it is since it's a dry cell it can be shipped via air.

 

I used the PC680 in my 23, mounted it by the rear axle. It was the only battery that would fit (7 x 7 x 3 inches thick). Before I bought it I called the company and spoke to the President, and told him I was worried it wouldn't start my 350 chevy. He said "I'm using the same battery to start my blown big block chevy !"

I had it in the car for the 5 years I owned it and it never failed to start, even after sitting without a charger on it for months at a time. When I sold the car it was still working great.

The only downside I might see is if the car has a lot of power drawing accessories. My car was minimal, as are most hot rods, so it was fine for that.

You'll be happy with an odyssey battery.
