97 Tahoe with spun rod, what to do?
My friend has a nice rust free 97 Tahoe that I found him couple years ago for $3,200. Truck now has 114k miles and is used to run from Denver up to the mountains for ski/fishing trips. Has been well maintained. Upon return from the mountains yesterday the truck has a rod knock. I'm thinking it was probably over-revved. It was full of oil (just changed it not long ago). It still has good oil pressure but certainly has a rod knock. I was pretty shocked considering the mileage...
Options are: Sell truck for next to nothing Rebuild existing engine Find a crate/reman engine Install Pontiac 455 What is the best option for replacement and a ballpark for cost? If we are going to put the $ into another motor I'd like to get something with more power. The stock 5.7 is a PIG. I see there are reman motors out there in the $2k range but those are not getting me too excited..

Verify it’s not the flywheel. I have replaced a few cracked ones in mid 90s Chevy trucks. Not sure if a common issue but sounds similar to a rod knocking.

Hard to tell from your video but if you YouTube cracked flexplates you will notice it has a similar tap as well more rapid similar to yours.
Good luck. |

What about rebuilding the engine using a stroker crank and a little more cam?

Repair the existing engine, not rebuild.
