I just got a 2003 Chevy 5.3L and want to build the engine for f/i. I read that you can go to the 5.7 piston size so I plan on going that route. What is the stock stroke and what can I stroke it to safely? I plan on adding a STS kit to it also since I have some in the garage collecting dust, lol. Who makes good strokers, cranks, rods, pistons, etc.?
Here are some pics of the project truck:
BTW, I was already told about the week tranny so a Level 5 is in order too. I don't want to go 80L with this project but maybe when I go to a 6.0 stroked to a 408 then I can.
