Re: 3.7 engine rebuild
Those are standard engine rebuild kits. If your bores need to be cleaned up, you'll need to get the oversized pistons, which ones depends on how much it needs to be bored to clean up the cylinder walls. Same goes for the crankshaft. If the main and/or rod journals are scored/out of round, they will have to be turned. Depending on how much will determine which oversize bearings you'll need. The only way you'll be able to tell all this is to tear it down and mic (micrometer) and inspect everything. If there is no appreciable wear, you'll be lucky and be able to use all standard size pistons and bearings. If the pistons aren't bad, you can also save money by reusing them.
