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........

I think they were produced in large numbers but they are getting real hard to find in useable shape. All the racers have used them up over the last 20 years.

Re: 010/020?
the 10 20 block is a desirable piece, and IMO, more desirable than 4 boltmains... you have them both, so that's cool.
The high nickle wears a LOT longer than the non 10 20 engines... very desirable in my eyes. Like I said in the thread linked above, I've seen 100,000 miles, and still see cross hatch from the hone... that's impressive. |
