Something Is Wrong With My 94 Ls Caprice

I just got my Caprice back from the body shop and now when I drive my car it's like the engine is "weak"...if that makes sense, I can't spin my tires anymore and when I drive on the loop I can't haul ass like I normally do, it's like the car is not shifting into gear I gotta 350 LT1 under the hood and everyone knows that an LT1 smashes to say the least and something is just not right...it'll get up to speed, but not the way a SS engine should can someone help me out???

Maybe the body shop guys beat the ever living crap out of it, but you seem to do a pretty good job of that yourself lol. Check for a vaccum leak. It's possible that a vacuum hose got unplugged if they had to tape off the engine area while performing the body work.
