I don't know about that one, the image shows your battery is only at 19% runaway

Actually, those are what I use on most of my stuff and the 120 IS deeper than the 90 amp. Hook 'em up to the old school solid-state Chrysler regulators. I think anything pre-Magnum (~1992) will have V-groove pulley on it. Smaller diameter is much better if you plan to spin your engine fast. The old American designs were never intended to be on an engine running 7000 rpm.
