Default Pistons and rods for boosted lm7

Im wanting to leave my stock bore on my 5.3 but since im going turbo i want to get better pistons anf rods. What would yall suggest? I dont really know much about it just want suggestions. I have 799 heads milled .030, a btr stage 1 turbo cam, nnbs intake nothing installed yet. Ive been reading many forums but havent seen much for my build. Im thinking of callies rods and maybe wiseco pistons but dont know what cc's.

just leave the motor alone. it doesnt need aftermarket rods and pistons until youre beyond 1000hp or your tune sucks.

I did a built LM7 long while ago. Stock crank, Eagle rods and Mahle pistons.

It's not wise to just say "leave it stock till you are over 1000 hp". Can it be done, yes.....do they last......no.

I would not run early gen 3 rods to 1000hp, they'll just snap in half and make a sweet window in the block.

GEN 4 piston and rods is a good investment or aftermarket rods.

the guy never said he wanted 1000hp. he is probably just a dreamer anyway and its going to be way more productive spending money on cam, fuel injectors or turbo kit instead of short block parts he will probably never actually install

I was actually shooting for 1000hp. Lol. But ill be happy with 800 for now. Ive had this truck for maybe 6 months. Already have 799 heads, nnbs intake, 4l80e swap since the 4l60e blew, truetrac, 4.10 gears, yukon axles. Cam i got is a btr turbo cam and a bg s475 turbo. This is my first chevy, ive always owned a ford. Blew my 14 5.0 motor so im thinking itll be cheaper to build my truck. Lol

I think im going with callies compstar h beam rods. Will these pistons do good with my 799 heads milled .030? Ive been reading that the stock crank is strong enough for the power i want. I hope so. Lol

WISECO 3.780" BORE, 1.300" COMP HT, 3.622" STROKE, 6.125" ROD, -3.2cc FLAT TOP PISTONS AW-07333
