I'm with the other guy, you should go with an LT1, great motors, I had one in my '79 Chevy at one point in time, but decided to revert back to my original 350 and build it up for a mud truck. Catfish around here don't like worms, they're more into liver, but what I use is peanut butter and corn (They seem to love it), put that in one of those things chicks wear, and you should be good (the things they were on their legs, they look see through.)
