Hank! I get what you're saying now. I drove her uncorked to the muffler shop yesterday. (about 2 miles) I just took it real easy on her. I went back and picked her up today! She sounds Good! The idle is real nice. The low end power is so-so but when she hits about 2500 RPM's the engine changes pitch and she really moves! I was cruising along and I dropped her down into first and wound her up and went through the gears and I got a great big grin on my face!
I'm impressed with how well the Holley 390 is doing straight out of the box. There's room for improvement but I'm pretty happy with her so far. Now I'm thinking about a new torque converter (considering this one is most likely the original) I'll keep you posted. Here's some pictures of the exhaust. 2-1/4" with a summit X-pipe and Thrush Turbo mufflers.





Thanks again to everybody for your tips, comments and compliments!
