Hey Everyone.

I just did a search, and nothing really answered my question.

Ive got a 5.3 Here that im planning on swapping into my '89 iroc.

Now, im aware of power differences, and im told an LS1 intake will best suite the 5.3 over a Fast intake or such.

ANYWAYS,

What is needed to swap the intake?

Can i re-use my injectors?
Fuel Rails?

Planning on swapping the TB to a cable one from the fly-by.

Kinda off to the side, but does anyone know the stock 5.3 injector size?

Thanks for your help!!!!

I have some flow charts, the truck intake does in fact flow better than the stock LS1... LS6 or FAST.... or better IMO... some of the FI 5.3's even run Vic Jr's
