a guy I met at a car show advised me that an odyssey battery would be a good upgrade for my roadster, there are several types available on line and I'm not sure what size I would need for my 350 chevy eng.
I'm running and Odyssey PC680 in my '31 with a blown 406. Starts it right up even when hot. It doesn't have much reserve, but if your car is setup, tuned right and, you don't want the stereo on when parked it's a great small battery. I too was skeptical prior to buying but, it worked out for me. I'm very pleased with the performance for such a small battery. Also, I keep a tender on it when not being used regularly.
Why??
OK since you asked first, yeah, they are good but not so sure that it's really an upgrade if you already have a perfectly functional battery system.
Do you need the weight reduction? Do you need the space reduction? If so, then when you need a new battery go for it - but be advised that the CCA don't match a conventional or Optima battery -
Oh and yes, I do have an Odyssey battery in my '31 roadster
Optima vs Odyssey:
Where it's mounted with the radio on top:
Before the change:
That wire hanging out of the trunk is for a Battery Tender just to make sure there is no parasitic loss over a period of time when not driving the car
Irelands child, not to hijack the thread but, are you happy with the PC680? Now that all the starting bugs are worked out, I'm really happy with the battery and it's small size. These Model A's have no space...
I've got the PC925 in my '32, cranked the 331" sbc just fine but I was wondering how it would do with the new 507" Cadillac ...... well it worked just fine also. They are small but pretty heavy for the size, totally sold on the Odyssey.
Mine is very small (comparison photo above), starts the car easily as long as the Edelbrock carb is reasonably full of gas and carries whatever load when needed (alternator not turning) plus freed up a bunch of trunk room.
Would I prefer a nice big conventional battery? You bet, but since I neglected a installing frame mounted drop out battery box when building the car - am 'living with' the Odyssey trunk mounted version.
Appreciate those nice words. It took a looooooong time to get it the way I wanted it to look
