<< I seem to loose a lot of torque with the open filter and gain no top end

Could my problem be putting headers on with the stock exhaust is a very bad
combination?
I am waiting for a catback system I ordered but the dealer installed the
headers when I bought the truck. Am I expecting too much from a 318? My 89
Shelby Dak ran better than this truck does.
That truck would smoke the tires 50 feet but had no high rpm performance. Of
course I know it was only 175 hp but was a little lighter than the 98. I
still believe the 98 should have more hp per pound. where am I going wrong.
Can I put a K&N
filter in the stock box and help myself. The underhood temp is just too hot
in Texas summer for underhood air input.
BTW I am running 87 octain gas, no ping at all and it cost 90.9. 93 octain
is 100.9 here.

Jim, I bet thats the problem, youre getting way to much backpressure trying to
suck that much air and then trying to blow that much exhaust into stock pipes!
Change your exhaust and try again! Those headers will work awesome then.
