Yup! the guys are on the right track, if you ask me. Your headers sound too big, your stall is way too low you will need a min of 3000, and your 400 trans is slightly dogier (although it's tough to feel the difference in the gearing) then the 350 so your 3.73 are min. If I'm not mistaking I think Lunati likes to use quite tight lobe angles giving lots of overlap so I would think 4.10 or even 4.56 would be better matched to your cam. As far as your headers go, they are sized correct for that huge cam as that cam will want to buzz at a high rpm. BUT, you can't have your cake and eat it bla bla bla. In order to allow the cam to do it's thing you have to allow that motor to breath - heads (AFR 200) with big exhaust but both these kill your low end torque. Your intake is okay but again not the best choice in my opinon, I think for your cam again I would go on the rev side of the scale and go with single plane (again kills your low end torque). So boils down to the big question do you want low end torque or top end horsepower. Torque, you will need to consider a different cam, and possibly 170 heads like Edelbrock, and smaller headers. Horsepower, you will need to get big heads min of 195 but better with 200's. Sorry for the epic novel but you need some changes before you will be happy, and we all want you to be happy. One final thought do you have room for a X-over in your exhaust? If you do get some white paint or heat crayons and mark your exhaust and run the engine up to temp and install a x-over in where your exhaust is still hot, this should help out on the bottem end torque a bit as well. Keep us posted on your changes/fixes.
