Here's my situation.. I have a 2008 4.8 with 799 casting heads. I'd like to install a new 5.3 crankshaft and scat or eagle h beam rods, and forged (wiseco most likely ) pistons. And would have this rotating assembly balanced. Is this feasible? The reason I'd like to swap into the 4.8 is its a clean gen IV motor that I have $130 bucks into. The motor will also have head studs and ls9 gaskets, and most likely s480 turbo for what its worth ..

Any guidance on this crank swap /rod/piston combination would be greatly appreciated. Thanks

Should work fine unless the block has different clearances then the 5.3? The 5.3 to the ls3 have the same crank the 4.3 has a smaller stroke! As for head studs alper motorsports has there brand for $65 and there nice I use it on my ls3! If you go with arp expect to pay $200+ for them.
