LS vs BB advice needed

[badazz81z28]

This has to be a joke right? You had a BBC that was capable of 9s and your disappointed a 6.0 LS production engine isn't comparable to that? Well duh! IMHO a 1/4 mile comparison is a pointless comparison unless the cars intent is to be a 1/4 mile bruiser. An LS swap is to take your old car and put modern power, drivability, handling, benefits of fuel injection etc. all in one. If you want nothing more than drag strip car, I agree the LS investment isn't needed. If you want a daily driver that runs good like a modern car and still puts out 500hp while getting 20mpg, the LS is the ticket. I think you had unrealistic expectations....However put a turbo or two on that engine and it will run that fast or faster in the right set-up. If your car isn't fun, your combination isn't right. A stock 6.0 has no issues making 500 crank HP.

The only N/A LS engine I have seen run 9s is a LS7 with MAST heads and even in that configuration much more all around better engine than the comparable 454.
