Burnouts and 4l80e's

[Scott2]

My truck is a '51 with a nice stiff TCI chassis, 9" rear with 4 link, a 2006 Silverado 2500 stock LQ4 6.0 and a rebuilt early 4L80e. I'm running 305/30R20 rear tires so there's a lot of tire on the ground. Only mods to the motor are the Hooker cast headers and K&N type air filter setup. I just had the computer all setup with the truck.

It runs great, starts off hard and accelerates really good, but no burnouts or hardly any real spinning at all. I'm more curious than anything as I see other guys on here with pretty comparable builds smoking the tires.

My tuner tells me most are probably running 4L60e transmissions and that the '80 sucks up a lot of power off the line. Of course, he's happy to port the heads, add a cam and bigger injectors, maybe add a looser converter and retune it and guarantees big smokey burnouts!

Again, wondering what others' experiences are?
