    Outside of the lack of power are there any known problems with the 6.2. I found a beautifull 91 Crew Cab Dually for a good price and I might not pass it up even though it is 2wd. I figure I could always upgrade with a Banks Turbo or even a engine swap in the future for the extra power but that will be at least 2 years from now.

    Check the harmonic balancer...when they go bad the crank breaks which kinda sucks. /forums/images/graemlins/grin.gif

    Starter nose supports usually are missing, then the ear of the block where the starter mounts up is prone to breaking.

    Mostly 6.2's are looked at with suspicion due to a lack of knowledge or understanding. If everything is up to snuff they are great motors. I really like mine.

    As for power, it's not too bad if you have decent gearing. Mine is pretty close to the same as my 350 was...and pulls much harder in a different way. Off idle there isn't a comparison, higher rpm's the 350 pulled harder.

    With a turbo like the Banks kit it'll pull quite decently, just keep in mind it'll never be a Cummin's.

    You'll really like the fuel economy...in a 91 2WD with an OD tranny it'll most likely get 18-20 mpg. Running 40's, 4.56's and the SM465 my truck gets a consistant 16-16.5 mpg. That kind of mileage is pretty easy to live with...
