5.3 Build up question Hello, I have some questions regarding my 5.3. I heard that I can bore it out 5.7? What else can be done? Is there a larger crank, rods that can be used? I plan on putting this to use in my 1988 Blazer. I have all the mounts, hardware and carb, intake, fuel system and headers.
I have test fit everything, and looks good. Now Im stripping down, painting, rebuilding chassis and rewire everything! Since the engine is out, and Im unsure of the intertals. This would be the time for a rebuild! Alot of questions, and other facts left out I know. But I have basic engine knowlege in small blocks, and only have 0% with the Gen III's 5.3 max bore and stroke.I know the heads will limit my flow needs, Im interested in what you all might have to say on the stock heads?
Your help and insite, or bashing would be a big help! Thanks alot! Hope to hear back. I ask all these questions, so when I go to local Machine shop I know, or have a Idea of what Im talking about!

Bad ***! Thanks Jim! I see you've built a Blazer too! Might be picking you brain!
Ls1 383 stroke kit, Will the heads be a issue? Or can I port them? What kit would you go with? Thanks again!

As far as power production goes... bigger bore is always better...
