010/020?
Casting question
 Just finishing cleaning the block and getting ready to paint and noticed the numbers 010 and 020 on the outside of the block as well as behind the timing chain. This was to indicate 1% nickel & 2% tin content on early 70's 350 casting's for ease of machining and add block strength? Were many of these blocks produced with a 4 bolt mains? Time to get this thing running this weekend, I hope........
