Re: Making Progress 03 Expy (Project Make'r run and Shine)
A master rebuild kit will cost you $500 and up. And you'll probably not be happy with the $500 kit, the better one costs closer to $700.You have it out, I'd at least take off the oil pan and visually inspect everything. If you actually pull the pistons, you really should replace the rings and knock the glaze off of the cylinders. Pull the bearings, replace them, etc., etc.
Since this was an evolution built on a shoe string budget, it's a tough decision whether to do a full on rebuild or not. If you have access to a dial indicator, I'd at least check radial and thrust play of the crank. Using a brass or stainless wire brush won't touch the base metal of the block or cylinder walls, and it really won't make a difference on the tops of the pistons if they get a few minor scratches. Green or brown scrubbie pads work also work well. It's a tough call, but being it's an '03, you've probably got close to 100K on her, it's a wise move to rebuild, but I know full well that you can't spend what you ain't got.
Ever notice that there's so many high performance parts available for GM products?
Did you ever think that maybe they NEED them?
