Ive searched internet and have read its possible to bore 4.8 and use rotating assembley from a ls1 to make a 5.7. Is there a thread on here anywhere on everything that needs to be done and what parts are needed to make this? I have searched and didnt find anything.

its rather simple. A 5.3 and 4.8 share the same block. Take the 4.8 block and bore it to stock ls1 bore and assemble with stock ls1 rotating assembly.
