Well, pulled the pan the other day and found the 3 middle main bearings spun from oil starvation at the last track day. Would like to keep the car all original if possible. does GM still stock the LT4 short blocks? couldn't find anything in my searches. Or would it be better to rebuild the original short block. the car only has 67K miles on it and everything else in the engone seems to be OK (heads, etc) Any suggestions?
