Can a gen 5 (2014) 5.3 SHORTBLOCK be used in a 2012(4.8).? Was going to do a cam swap of course, run the 243 heads and intake, injectors. ANYONE?... I've been googling for 2 days, almost all swaps are gen 3 or gen 4 to gen 3 etc... There is a 2014 COMPLETE 5.3 close to me at a great price.

This may help. My answer is I am not sure

Edit: After doing some light reading I am going with no. I do not think that any of the gen 4 heads bolt up to the LT1 making it basically a waste of time. I believe some of the block internals may be different as well, something about oiling and oil pressure, which may cause this to not work at all.

 

Not directly

Gen 5's have the HPFP inside the motor, to supply the DI heads. I know you said cam swap head swap blah blah

But I am not certain you can actually retro back like that because the blocks are so different. I think it would actually be easier to maintain the DI and do the gen 4 to 5 conversion rather than built a gen 4.5

 

Thanks guys, we found a few other videos this am...Oh well, back to hunting!

 

THis crushes my spirit lol
