Those Running 3.73 And a TF w/ LockUp.. What's your highway Driving Like?

I respect the replies. My 340 when built in 1996 an had had 360hp, but the torque band didn't come on till 2600rpm. It has a purple shaft that I think has 460 lift. Think back 20 years and the parts available then. It has an air gap intake and a 750 Edelbrock from back then. Mechanical advance at 2000rpn is 35 degrees. I can't go any more or it knocks. I'm stuck with what I have. By the way, the vacuum is low, 7 pounds and I have a vacuum pump to run the brakes. It probably should be pulled and rebuilt, but I'll leave that to my son after I kick the bucket.
