Moparguy, how well does the T-5 work in your 3/4-ton truck?
Frank, it works Great. The frequently heard concern is a T5 isn't nearly as robust as the original SM420. And that's true, however few will work their truck as hard as GM engineered the 3600 and 3800 trucks to work. When these truck worked for a living they pulling loaded grain wagons, loads of logs, stock trailers or hauled loads that likely far exceeded their rated GVWR. I find my T5 with 4.03 1st and .72 5th to be very capable when doing the light to moderate work my truck does frequently. Hauling hay and fire wood are the most frequent work truck jobs.
Best is how it quietens the engine down by dropping revs. The T5 and 4.10s have made the old rig a comfortable 60 (plus) mph highway truck. Before in pure stock trim, 50 was the fast happy speed.
Lots of info here and on the interweb dealing with how-to info for the conversion.
