Engine Upgrade 2017 ppv

[Ebutler2200]

I bought a retire squad, only has about 50k on the body but 16k hours on the motor. So some parts are now failing. Question is what is the largest engine I can drop into it that will fit to the trans/transfer for 4wheel. Probly gonna upgrade trans to the 10 speed if It maintains 4w. Most likely looking to get a short block from the chevy performance site or something of similar. Also would like to be able to make it pass emissions if possible. Its a project truck so looking to build something somewhat rediculous. If it cant pass emission I can register it in a non emo county. thnx

No externally physical difference between a 4.8L, 5.3L, 5.7L, 6.0L, 6.2L, 6.6L, or 7.0L. All the same size on the OUTside, all cast identical shadows.

It's a project truck so looking to build something somewhat ridiculous.

You'll get more bang for your buck from slapping a supercharger onto a 6.0L or 6.2L; both of those are easy enough to find.

Forgot the guys handle on here but he did a 6.6L with the 6L90.

@L8T BURB is the guy. He has good insights abiut his project. His thread was full of good info.

Personally I would just do a 6.6L HD motor and call it a day. I'm currently contemplating that for my 2017 Denali with a 6.2L that bent a pushrod on #4. It's back running again with a new pushrod and oil change. So, depending on what I decide to do with the vehicle, a 6.6L swap may be on my future list as well.
