Great progress. One thing is bothering me though. With the build date on your motor it probably came out of a 67 coronet. All the 66 nets i,ve had with 318s were poly style.Not 100 % positive but dont think la nets came out till 67
it was a typo I made at the time and realized it much later but I can't edit my original post since its so old and I never bothered correcting it as I had hoped most of you would understand where I was coming from lol.
I believe the block year was a dated as a late 66 making it a 67 (if I remember correct) but was from a 67 coronet.
