X block sonic test
I have my block back from the machine shop.
Sat over at his shop awhile, as his sonic tester didn’t come back after loaning it out. he purchased a new one, and said it’s pretty safe to bore to at least 4.100 with a little block fill maybe more.
currently it’s a fresh 4.04 as the block was ran as a .030 over 318 bore.
Thoughts on potential bore size?
Is decking some a good idea?
