Been a little sporadic in my work on the runner and my progress posts but I had some time last night and figured I’d focus a little on the engine. Since I’m getting ready to send a block out to have machined ( I had 2 440 blocks, 72 and a 77) I wanted to inspect them and choose the one to go out. 77 is a bare block that purchased with another engine which I know nothing about. The 72 is the one I pulled from the car and was already down to a short block. 72 is a forged crank, .030 flat top slugs. After popping the pistons out I found I had 6 busted top rings!!!! Might have had a detonation issue ya think?! Good news is the cyl walls are good and can probably be just honed and done. But to end this long story, I’m going to used the 77 because it’s a std bore to start and for reasons found in a write up on 440 source. Unless someone here has other info they wouldn’t mind sharing. Thanks for listening,,,,,,,,, er, reading
