Done with Magnum Swap!
Whats done to his 454? Its real easy to run low-mid 12s in a full bodied chevelle with a 454 if it has a few goodies, I'm running a very mild 469 BBC in my G bodied Cutlass & loving it.
Those 71 Swingers are light, alot lighter then most think. Car looks great, mine looked very close to yours, i'll see if i can post a pic or 2, you'll freak lol, Did you check out the video?
