Not Ranked
Rick, the 3550 is in since 2003 sitting behind a very good modified 351C. A lot of times with high speed use on the autobahn up to 260 Km/h(161mph) in 4th, never in 5th !!
The 5th was and is just used to lower engine rpm after i reached 80 mph, never at lower speed and never to speed up quickly in 5th.
No issues at all but not the low end torque i will have with the FE.
Very close to tested dyno reality this is what i have right now with the cleveland. I'm allways above 2500 rpm with 7000 set as limit by the ignition box.
I hit the limiter a lot of times 
The most destructive situation for the tranny will be the higher torque at low rpm.
You are absolutely right.
I used the 3550 times as a normal 4 speed because of its 1:1 4th gear, 5th was just selected on autobahn.
