since v8's don't use 1st, and second is not interchangeable.
what is the latest thinking on the best gears for 3,4,5 ?? stock is ok - but @ 3000-3500 rpms at @ 65 mph - really sucks the gas : (( jim |

Jeez! $400 for a GA set? I wish I could get that much for them, I have had a few.
There are a few options, all depend on money. 1) Put an H in 5th and call it a day. Easy, fairly inexpensive (compared to other options). 2) 904 main shaft and any 2nd gear set you want to dick with (min $1800 for the shaft alone. Chris Foley may make you one for less, but then you still need to buy the gears for about $400 a set). 3) Find the correct sporto tranz and use the r/p out of it as it is a shorter one that will drop RPM in all gears. I have an incorrect one (wont work as a direct fit in a 901), and I think I know how I can make it work using a 912 intermediate plate to bring the pinon into the diff a little more (PM me if you want to be a guinea pig). The rest is a colossal waste of time. You will not do better than a flipped H in 5th in a stock transmission. The gears that Mark was talking about are probably a Z gear which is a stock 5th in a /6 box. The $400 GA set is a stock 2nd in a /6 box and not that rare, IMHO. |
