Lnorm

Just sold most of my sbf stuff. Drove 3 hours each wsy yesterday for a low mileage lq4 to find out the oil pan blew out during the accident. No idea how long it ran without oil or if it even did. Not a chance I can afford. My question is where's the best place other than eBay to get a good deal on a dropout? And what cam/springs should I put in it for good hp with a 125 shot of nitrous?
