My daughter thought that only the oil change guys check the oil and since it wasnt leaking that there was no problem. Well, she now knows that it can be a problem because now she has the ROD KNOCK!. It's a 98' Tahoe with 5.7 Vortec
Question: If I pulled the motor, is it possible or even feaseable to put in new rod and bearing or is the crank toast and the motor pretty much shot? What would be a good solution. Used engine for $800 / short block $400-500. Will a 350 short block work with this motor or do I need a 5.7 Vortec short block.
If I found a say carborated or earlier EFI, would that swap over with out too much trouble? Or toss a road flare in it and walk away. GEEZ

Chances are she will need a new crank. I would recomend looking into a company like Jasper. They make decently priced rebuilt engines with a good warranty. Ask your local automotive shop about pricing on one installed. Also, the 5.7 is a 350.

Thanks for your reply. Since its a 350, will any late model 350 long block, say a 1996 thru 2000 work for transferring over the "Vortec" stuff on my bad engine over to the long block or does it need to be a Vortec block?

I would stick with the vortec family of 350s 1996 through 2000 just to be on the safe side. They are very common to find some with fairly low miles in a boneyard.
