Re: Help.
Look for the casting # that ends with 062. There are 906's too but there are some out there that actually hurt performance, nothing a good valve job won't fix though. Vortects also have a .480 lift limit stock so you either need to get beehive springs or have them machined to take higher lift, search for more specific info.

Re: Help.
Maybe even show some real intelligence, do a little searching, then ask for some input based upon what you've determined on your own.

Re: Help.
When we talk about a Vortec engine we are talking about 96-2000 350 truck engines. Others may be labeled Vortec by GM but do not have the Vortec heads and the roller cams etc. The 5.3 truck says Vortec but is actually an LS based engine.
The question is what you are trying to do and what your goals and expectations are.
With this in mind Z28ricer isn't that far off.

yes but you are a little more diplomatic about it, Z28ricer needs to remember he too was ignorant once upon a time, we all need patience when we are among the unknowing and unlearned. I was an

Re: Help.
I'd be more than happy to help him 100%, but its going to require a little bit of information to get him pointed in the right direction, though the reality is, unless you are looking to waste a lot of time and money, going at minimum LT1, or 5.3 is the best choice.
Things needed for accurate and useful help:
Year the vehicle is, what drivetrain is in it
Planned drivetrain (auto ? manual ? CVT ? Caged unicorns ? )
Budget
Existing mods
Emissions requirements
Planned driving, or target for best performance (drag, drift, just street, autox)

Re: Help.
An LR4 will certainly get it down the road better than any stock thirdgen powerplant, and while it would be towards the lower end of the list for my first picks of what to swap in, it would certainly be above anything Gen1.
Keep in mind to install it you'll need the usual LSx swap fitment stuff, a car intake manifold, and preferribly front accessorys or modification of the truck stuff to clear the intake manifold.
One of the all aluminum 5.3's can generally be found for around $600, has a good bit more power, a set of 243 casting heads, and weighs less.

Z28ricer is correct we do need more information, before we can give SOLID info and ideas, what are your capabilities as a mechanic, are you willing to learn more...... ect
