Where'd you get your engine from? I have a house not too far from Brunswick but haven't seen any engines for sale in my area. Basically I'm looking for somewhere that has parts for our trucks in the south Ga. area. Good job on the swap man; even though you say its easy I think it'd take me 100x as long to do as it did you

I found it on car-part.com locator website. I took a day off work and drove 5 hours one way to get this baby. It was all worth it. The place was called allpro in Aurburndale, fl. when I say its easy, I mean you can follow the normal instructions for replacing an engine and get these results. Its easy compared to port and polishing heads or building a forged internal motor.

Are the injectors the same in size between the 4.8, 5.3 and 6.0L engines, for someone who might get the long block less intake and injectors?
Will the fuel pump of the 4.8L truck be enough for the 6.0L engine?
Will it run with the 4.8L tune and be okay to drive until it get tuned?
