Well so far what I know is I have a 1976 high nickel and tin block made in Canada it is 4 bolt main it was stamped on April 17, 75 or 76 and could have a problematic valve train, but mine has been replaced. Any way and most important to me is that it is a Chevy!!

I could really care less if it was 4 or 2 I am not racing just my daily driver was in my 1985

for the last 6 year! Now at home deep in my
1967 C-10
Not sure why everyone got caught up on that I wanted to know just a little history, so when I am at the gas station or a car show and some one ask I don’t stand there catching flies with that dumb look on my face!!! lol
Man you guys are very helpful Thank You!
Now my next question where do I find the extension for brake peddle Rod and how long is the right length?
