[RICK LAKE]

madmaxx There are getting to be alot more aluminium motors broken because, there are alot more guys racing them. The old stock blocks are drying up and getting harder to find a 427SO with stock bore and NO SLEEVES in the block. No matter how good the motor builder is, there is a guy out there that can break that motor in 20 minutes. We went from SB/BB to a material and stress question. A windowed aluminium block can be repaired alot easier than iron one. They have come out with an iron spray for repairs that is better than any welding rod repair. I don't have alot of info on this. After I assembly my motor, I have had no need to go back and retorque, bolts,nuts, and screws. The rockers are the only thing I check after the 2 breakin periods. Motors are living breathing things, just let them eat. Rick L Ps I do limit the max rpm's for my strokers.
