Best gears for a /6 ??
is a 7.25 really that bad....they were put in millions of vehicles and seemed ok
No, it isn't bad, but it's not the greatest if it's an open diff. & You're beatin' on it w/a stick & bootleg burnouts! My personal experience with an open 7.25 failure
was behind a cammed 318 in My '69 Dart, and I can tell You I left many huge clouds of tire smoke w/it before the diff spit the spiders out & left 'em in the
bottom of the housing. It was an auto at that time, but upon inspection it also wasn't exactly full of lube, thus encouraging the galling & heating that leads
to spider gear oblivion :rolleyes:, that part was on Me. That engine ran well enough to get My Dart just over 94MPH thru the traps when I ran it, and I can honestly
say I couldn't remember how many burnouts before it let go, but it was in the dozens..............probably over 40.
That said, since You're already converted, there are those who have switched their 8.25 to small pattern, the drums & axles need drilled, and the drum
meter/register/hub section needs turned down. Not that difficult to do for any competent machine shop.
Ratio? The 3.55's.............................
