I agree with db,a set of small primary tube street headers are about the most bang for your bucks. A little more torque and HP plus a good chance of gaining a bit of fuel economy. With a non electronic carb you may have to rich up the primary jets/metering rods 1 step richer,as headers tend to lean out the mixture. If fuel injected or electronic carb,make sure the header has provisions for the oxygen sensor.without it your mpg will go way down. also if the oxygen sensor is the 1 wire type and has 50,000 or more miles,replace it. I just replaced the dead oxygen sensor on a 92-454 pickup and gained nearly an extra 100 miles per tankfull with a $20 0xygen sensor. When they die they tell the computer to go to the full rich setting.
