Will I be happy with a 6.0?

I recently purchased a new farm truck. It is an 86 military 1.25 ton pickup with 10,000 miles. For those that don't know it is a 6.2 diesel, turbo 400, 208, 4.56 gear. My old truck was a 427bbc, sm465, 205, 4.10 gear. I drive the truck daily but only a few miles. During the summer when I don't have a sanctioned pull to take my 4x4 superstock truck to I drive my driver to the local brush pulls and pull it. My plan was to take my 427 out of my old pickup and put it in the military truck(My old truck is a rusty peice of crap). In the corner of the garage sets an 02 6.0 out of a denali with so I was told 32xxx miles. My old 427 is a 9.5+.1 compression, closed chamber large ovals, 69 ss high rise cast manifold with an 800cfm q-jet, factory stainless exhaust manifolds, 2.5 exhaust, 262comp extreme 4x4 cam, and roller rockers. I think a flexplate is all I have to change to switch them which I'm sure I probably have which = cheap! In the corner of the garage sets an 02 6.0 out of a denali. If I use it I would like to mill the heads and throw a camshaft at it and obviously a tune. Most of our "stock" truckpull classes require 15" of vacuum at 850 rpm and stock manifolds intake and exhaust. I won 5 of the 6 pulls I entered with my 427 and might have won the sixth one if it weren't for a faulty fuel pump. I probably tow a heavy load twice a month and its not that far anyway. How would the 6.0 stack up against my current bbc(daily driver,occasional puller)?

Out With The Old,in With The New:)

Decisions, Decisions.... I think I'd hang with the BBC for what you're using it for. :twocents:

As far as power you will probably be stepping down. But for a daily you would be stepping up. So really it would be what more important to you....

Yes, one time to reco a BBC.

;)yea im sure yull like it!

the 6.0 is more efficiant, but it won't be the tq monster that the 427 is. if you want a better daily with good power I would swap in the 6.0 if you want a pull truck I would stick with the 427.

Im with them on the BBC. Hey, will that th400 fit on a 6.0? If so, do you want it?

Well I finally got to pick my "new" truck up this week and luckily it was all I expected it to be plus some. Drives like a new one! Fixed a fuel leak on the old 6.2 and runs like a top. I've decided to leave it in temporarily till it cracks a head, breaks a crank, or I just get bored with it(won't be long anyway). Still haven't decided on bbc or 6.0. I was a little disappointed with you guys, I thought there would be more bbc haters on here. Just kidding! How much horsepower could I expect to get out of a 10.5:1 6.0 with a mild/moderate cam and a tune through factory exhaust manifolds. I figure my 427 is making less than 400? I know my bbc will have a ton more low end torque, but low end torque is for tow trucks, it doesn't win truck pulls.

you should easily get close to 400, the bbc will have more low end, but any large cube motor will have more low end.
