Default starting a 6.0 swap..should i go forged or stay stock..? shootin for 650 to the tire

ok guys i picked up a good LQ4 with 112k miles on the clock. ive heard about alot of stockers surviving lately but i really would like some reliability out of this motor.. the plan so far is sloppy stg 2 cam..pac 1218 springs.. 7875 billet turbo. decap 80s on E85. should i really spend the money on forged rods and pistons.?? is there anything else i should do..or even a better combo to make 650 tire..? any input is greatly appreciated..!!!

You probably don't NEED forged rods/pistons for that level, but it's better to be safe than sorry.

The forged rods/pistons will give you some room to grow, too.

With a good tune that lq4 should take everything that 7875 has to offer. Is it a gen3 or 4 motor?

im doing a 5.3 with a cast 7875 on e85 with 1500cc injectors. now i didnt gap the rings because i heard if you run e its less chances but then again it also depends on your tuner! but if your have the engine out might as well. my next junkyard engine i will be gapping the ring for added insurance. now again, if you gap too big you will blow white smoke

Youd have to do retarded big gaps to get what I would call excessive blow by. Like 26-28 thou and send it.

A quote that has been passed around on here alot- original author unknown at this time.

"If your ring gaps are too loose only you will know, if they are too tight everyone will know".

you need to take it apart to gap the rings but the bigger issue ive seen is it will be carboned up pretty bad. gap it to .025 and it will make good reliable power if the tune is right.

yes gapping is like added insurance imo!

but to me the biggest part is your tune, if tune is garbage then nothing can save that
