Unless you swap out the intake manifold neither of those throttles will bolt on.

What are the plans for the truck?

I don't even see a need to upgrade the stock manifold unless you going to be some serious power adder.

Just swapping intake isn't a very smart or sound way to try and increase hp on a stock engine.

Start with a cam and exhaust or just jump into a turbo build.

Why is that not a good idea to upgrade the intake man and upgrade the tb 2 a 102m will that cause problems.along with the cam and dual exhaust.

you will spend $1800 on an intake and TB which will get you 30hp or so.. 5.3 and stock heads dont really respond well to intake mods..

or you can spend $300 on a used cam and get 50hp

LS engines like exhaust mods, cams, and BOOST.
