Think I spun a bearing. Got a pretty wicked knock coming from what appears to be the rear of the block. How screwed am I? I am no mechanic, so I will have to pay somebody to fix this. I talked to one shop, and they're talking like $1500, because they said the crankshaft is probably scarred up. I just had the top end rebuilt like 2000 miles ago, so I'm thinking it might just be cheaper to get a short block. What do you guys think? Spring is almost here, I have 3/4 ton axles waiting to go under, as well as sliders. I did NOT need this crap right now!
