[V8] 5 spd conversion: 3.6 vs 4.2

[Ed Kellock]

Some time ago, it was believed that the '91 cars with automatic tranny got the 3.89 fd ratio, but more recently I think Keith has shared that every '91 auto he's seen has had the 4.11.  The 5spds all have the 4.11.  If the '92 and up had the 3.89 that wouldn't help us, but I think they all had 4.11's.

hhhhmmm....


thought I remebered that a 90 V8 had a higher final drive ratio
than a 91 auto ?  so the 90 was supposed to be quicker, while the
91 got better gas mileage....
