For a novice, it would be difficult. I've been turning wrenches for 30yrs +. It took me 6hrs to install a set of LT's on mine & same for a friends.
You have to remove the motor mounts, starter & original manifolds, jack up the engine. Some brands also require unbolting the steering shaft.
I'd do some reading on the subject & see if it's something you feel you could handle before commiting yourself.
I agree completely. Its not a job for a novice to try. L/T is the way to go depending on which brand you get will give you ground clearence problems AR, Kooks and I beleive Stainless Works don't have clearence problems. I have American Racing with catted H and have no problems.
