That sort of defeats the purpose. The MPFI intake is part of the Vortec package.

I've decided I will leave the engine stock for now and just drop it in the truck. I'll use the Headman Elite headers I already have, then get an aftermarket air intake setup and a custom tune flashed in the PCM. That should put me real close to 350HP with gobs of torque from off-idle to 4500rpm or so. The 4l80e trans with stock locking torque converter and a 3.42 posi rear end should let me get pretty decent fuel mileage and still have a lot of fun.
