I hope to be high 8's once I get the converter /cam deal worked out... Right now with this stall I don't need slicks... But with that 4000 I bet I would lol ... But maybe a smaller cam I could keep the converter and run same size tires into the 8's

Cam is too big and converter is too small for that 4.8L...
