4.7 Finally Dead. Future upgrade plans

[TheEnder]

Hello everyone.

Welp, my 4.7 finally kicked the bucket recently. Started with what sounded like piston slap, pulled the head, found some decent wear in cyl 7 along with the piston itself being easy to move and slapping along the bore causing the noise.

I’m moving to TX in a few months because cali has gone to crap. We all know why that is, and im not going to talk about it more from there.

Goal right now, since the truck has absolutely NO rust anywhere, and is in very good shape aside from the engine is:

- Pull the bad piston/rod from the engine
- Hone out the bore wear, get a new piston/rod combo, just to make it the drive to TX
- Drive it around for a bit in cali, to break it all in, and then make it to TX
- Once in TX, pull the 4.7 and the trans, and swap in a SRT 6.4L/8HP turn-key crate engine. Then turbo/cam both later on.

Given truck prices now, and the fact i will never be able to part with this truck, i think this will be for the best.

I'd look closer at the truck 6.4 if you're going to boost a 6.4. It'll take more boost on it's stock pistons then the higher compression car/jeep 6.4 will take on stock pistons,plus the truck 6.4 has better heads. With a valve spring and valve swap,you basically have hellcat heads,with a naturally aspirated intake manifold bolt pattern.
Good article here on the truck 6.4.

Our 392 BGE Hemi build-up journey starts with buying a mysterious junkyard Ram Truck 392 Hemi core. We crack it open and find the mother lode!

Thank you, you just gave me even better ideas! Lol.

Truck 6.4s are a bit cheaper too. Would be sick!
