Best solution, spun bearing

[redtransam]

hello all, I used to be NMredLS1 on here.

Here is my delima, I spun a bearing...I'm fearing it may be the main bearing in my car. I had pulled the engine and taken it to a shop, thinking I had some money available to fix it with a stroker, heads, injectors, exhaust and lots of goodies. Well some stuff came up, and that didn't go through and now I'm looking for the best route to fix my car, I have about $3,500 saved up to spend on this project.

TIA,

Joel

Without tearing the engine apart, it is hard to say without knowing if the crankshaft is ruined. I've seen the blocks damaged beyond repair as well. Bob

Well im an LT1 guy and i have an iron block i started to spin a main on my motor it didnt flatten the tabs all the way im getting the line bore checked anyway and my machinist said if they had to hone it $125 being that your block is aluminum cant see why if it did chew the block up that bad why someone cant tig weld the main bore up if you were to have to take out alot of metal to make it round agan.

went and talked to a friend at a local shop today, he seemed to think that tenatively the best solution is get a 383 stroker from eagle and do that for now, that'll replace everything, unless the block is screwed up. He's going to tear into the engine this week and let me know if he sees any other problems

While I don't know for sure, it seems roughneck has the right idea. Until you tear it down, there is no way of knowing how extensive the damage could be. Aluminium is much easier to repair than cast iron, so even if the crank needs to be replaced, you should be able to get it welded to replace any damaged metal, then line bored back to the correct size. See what an estimate for all the parts, labor, welding and machine work will come to, then decide if you want to go that route, or consider something like this:

you could get a short or long block on ebay for less than it would cost you to repair your block. granted sometime there are unscrupulous sellers but if you pay through paypal and the item is not as advertised, paypal will usually get your money back.

I just finished tearing mine down after spinning a rod bearing. It looks like all I'll have to do is replace the bearings and have the crankshaft journal cleaned up. This was the best case scenario. Worst case is you have to replace the entire block, crank, rods, etc etc. You just won't know until you get it apart.
