ok i just bought a 1981 2 door chevy impala with a 454 and a turbo 350. The 454 is gutless it seems to me and not that reliable so i was thinking of getting a ls1 or ls6 or somrthing along those lines. Could i bolt the ls motor to my turbo 350 ? Or should i just buy a 4l60e ?

here are some pics of my project as you can see there is plenty of room in the engine bay lol






Any help would be GREATLY GREATLY APPRECIATED
